-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Cisco Security Advisory: Cisco IOS Internet Key Exchange Vulnerability Advisory ID: cisco-sa-20120328-ike Revision 1.0 For Public Release 2012 March 28 16:00 UTC (GMT) +-------------------------------------------------------------------- Summary ======= The Cisco IOS Software Internet Key Exchange (IKE) feature contains a denial of service (DoS) vulnerability. Cisco has released free software updates that address this vulnerability. This advisory is available at the following link: http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-… Note: The March 28, 2012, Cisco IOS Software Security Advisory bundled publication includes nine Cisco Security Advisories. Each advisory lists the Cisco IOS Software releases that correct the vulnerability or vulnerabilities detailed in the advisory as well as the Cisco IOS Software releases that correct all vulnerabilities in the March 2012 bundled publication. Individual publication links are in "Cisco Event Response: Semi-Annual Cisco IOS Software Security Advisory Bundled Publication" at the following link: http://www.cisco.com/web/about/security/intelligence/Cisco_ERP_mar12.html Affected Products ================= Vulnerable Products +------------------ Cisco devices that are running Cisco IOS Software are vulnerable when they are configured to use IKE version 1 (IKEv1). A number of features use IKEv1, including different Virtual Private Networks (VPN) such as: * LAN-to-LAN VPN * Remote access VPN (excluding SSLVPN) * Dynamic Multipoint VPN (DMVPN) * Group Domain of Interpretation (GDOI) There are two methods to determine if a device is configured for IKE: * Determine if IKE ports are open on a running device * Determine if IKE features are included in the device configuration Determine if IKE Ports are Open on a Running Device +-------------------------------------------------- The preferred method to determine if a device has been configured for IKE is to issue the "show ip sockets" or "show udp" exec command. If the device has UDP port 500, UDP port 4500, UDP port 848, or UDP port 4848 open, it is processing IKE packets. In the following example, the device is processing IKE packets in UDP port 500 and UDP port 4500, using either IPv4 or IPv6: router# show udp Proto Remote Port Local Port In Out Stat TTY OutputIF 17 --listen-- 192.168.130.21 500 0 0 1001011 0 17(v6) --listen-- UNKNOWN 500 0 0 1020011 0 17 --listen-- 192.168.130.21 4500 0 0 1001011 0 17(v6) --listen-- UNKNOWN 4500 0 0 1020011 0 !--- Output truncated router# Determine if IKE Features are included in the Device Configuration +----------------------------------------------------------------- To determine if a Cisco IOS device configuration is vulnerable, the administrator needs to establish whether there is at least one configured feature that uses IKE. This can be achieved by using the "show run | include crypto map|tunnel protection ipsec|crypto gdoi" enable mode command. If the output of this command contains either crypto map, tunnel protection ipsec, or, crypto gdoi then the device contains an IKE configuration. The following example shows a device that has been configured for IKE: router# show run | include crypto map|tunnel protection ipsec|crypto gdoi crypto map CM 100 ipsec-isakmp crypto map CM router# Determine the Cisco IOS Software Release +--------------------------------------- To determine the Cisco IOS Software release that is running on a Cisco product, administrators can log in to the device and issue the "show version" command to display the system banner. The system banner confirms that the device is running Cisco IOS Software by displaying text similar to "Cisco Internetwork Operating System Software" or "Cisco IOS Software." The image name displays in parentheses, followed by "Version" and the Cisco IOS Software release name. Other Cisco devices do not have the "show version" command or may provide different output. The following example identifies a Cisco product that is running Cisco IOS Software Release 15.0(1)M1 with an installed image name of C3900-UNIVERSALK9-M: Router> show version Cisco IOS Software, C3900 Software (C3900-UNIVERSALK9-M), Version 15.0(1)M1, RELEASE SOFTWARE (fc1) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2009 by Cisco Systems, Inc. Compiled Wed 02-Dec-09 17:17 by prod_rel_team !--- output truncated Additional information about Cisco IOS Software release naming conventions is available in "White Paper: Cisco IOS and NX-OS Software Reference Guide" at: http://www.cisco.com/web/about/security/intelligence/ios-ref.html Products Confirmed Not Vulnerable +-------------------------------- Cisco ASA 5500 Series Adaptive Security Appliance is not affected by this vulnerability. No other Cisco products are currently known to be affected by this vulnerability. Details ======= The IKE protocol is used in the Internet Protocol Security (IPsec) protocol suite to negotiate cryptographic attributes that will be used to encrypt or authenticate the communication session. These attributes include cryptographic algorithm, mode, and shared keys. The end result of IKE is a shared session secret that will be used to derive cryptographic keys. Cisco IOS Software supports IKE for IPv4 and IPv6 communications. IKE communication can use any of the following UDP ports: * UDP port 500 * UDP port 4500, NAT Traversal (NAT-T) * UDP port 848, Group Domain of Interpretation (GDOI) * UDP port 4848, GDOI NAT-T The IKEv1 feature of Cisco IOS Software contains a vulnerability that could allow an unauthenticated, remote attacker to cause a reload of an affected device. An attacker could exploit this vulnerability using either IPv4 or IPv6 on any of the listed UDP ports. Spoofing of packets that could exploit this vulnerability is limited because the attacker needs to either receive or have access to the initial response from the vulnerable device. This vulnerability is documented in Cisco bug ID CSCts38429 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2012-0381. Vulnerability Scoring Details ============================= Cisco has scored the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this security advisory is in accordance with CVSS version 2.0. CVSS is a standards-based scoring method that conveys vulnerability severity and helps organizations determine the urgency and priority of a response. Cisco has provided a base and temporal score. Customers can also compute environmental scores that help determine the impact of the vulnerability in their own networks. Cisco has provided additional information regarding CVSS at the following link: http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to compute the environmental impact for individual networks at the following link: http://intellishield.cisco.com/security/alertmanager/cvss * CSCts38429 ("Cisco IOS Software IKE DoS vulnerability") CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of the vulnerability may cause the vulnerable device to reload. Software Versions and Fixes =========================== Cisco IOS Software +----------------- Each row of the following Cisco IOS Software table corresponds to a Cisco IOS Software train. If a particular train is vulnerable, the earliest releases that contain the fix are listed in the First Fixed Release column. The First Fixed Release for All Advisories in the March 2012 Bundled Publication column lists the earliest possible releases that correct all the published vulnerabilities in the Cisco IOS Software Security Advisory bundled publication. Cisco recommends upgrading to the latest available release, where possible.

Cisco Security Advisory: Cisco IOS Software Reverse SSH Denial of Service Vulnerability
by Cisco Systems Product Security Incident Response Team 28 Mar '12

28 Mar '12

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Cisco Security Advisory: Cisco IOS Software Reverse SSH Denial of Service Vulnerability Advisory ID: cisco-sa-20120328-ssh Revision 1.0 For Public Release 2012 March 28 16:00 UTC (GMT) +--------------------------------------------------------------------- Summary ======= The Secure Shell (SSH) server implementation in Cisco IOS Software and Cisco IOS XE Software contains a denial of service (DoS) vulnerability in the SSH version 2 (SSHv2) feature. An unauthenticated, remote attacker could exploit this vulnerability by attempting a reverse SSH login with a crafted username. Successful exploitation of this vulnerability could allow an attacker to create a DoS condition by causing the device to reload. Repeated exploits could create a sustained DoS condition. The SSH server in Cisco IOS Software and Cisco IOS XE Software is an optional service, but its use is highly recommended as a security best practice for the management of Cisco IOS devices. Devices that are not configured to accept SSHv2 connections are not affected by this vulnerability. Cisco has released free software updates that address this vulnerability. This advisory is available at the following link: http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-… Note: The March 28, 2012, Cisco IOS Software Security Advisory bundled publication includes nine Cisco Security Advisories. Each advisory lists the Cisco IOS Software releases that correct the vulnerability or vulnerabilities detailed in the advisory as well as the Cisco IOS Software releases that correct all vulnerabilities in the March 2012 bundled publication. Individual publication links are in "Cisco Event Response: Semi-Annual Cisco IOS Software Security Advisory Bundled Publication" at the following link: http://www.cisco.com/web/about/security/intelligence/Cisco_ERP_mar12.html Affected Products ================= Vulnerable Products +------------------ Cisco devices that are running affected Cisco IOS Software or Cisco IOS XE Software versions are vulnerable when they have the SSH server enabled and allow SSHv2 logins. Only SSHv2 is affected. To determine if SSH is enabled, use the show ip ssh command. Router#show ip ssh SSH Enabled - version 2.0 Authentication timeout: 120 secs; Authentication retries: 3 The previous output shows that SSH is enabled on this device and that the SSH protocol major version that is being supported is 2.0. Possible values for the SSH protocol versions that are reported by Cisco IOS are: * 1.5: only SSH protocol version 1 is enabled * 1.99: SSH protocol version 2 with SSH protocol version 1 compatibility enabled * 2.0: only SSH protocol version 2 is enabled The SSH server is not available in all IOS images. If the show ip ssh command is not available, the device is not vulnerable. Devices that do not support SSHv2 are not vulnerable. To determine the Cisco IOS Software release that is running on a Cisco product, administrators can log in to the device and issue the show version command to display the system banner. The system banner confirms that the device is running Cisco IOS Software by displaying text similar to "Cisco Internetwork Operating System Software" or "Cisco IOS Software." The image name displays in parentheses, followed by "Version" and the Cisco IOS Software release name. Other Cisco devices do not have the show version command or may provide different output. The following example identifies a Cisco product that is running Cisco IOS Software Release 15.0(1)M1 with an installed image name of C3900-UNIVERSALK9-M: Router> show version Cisco IOS Software, C3900 Software (C3900-UNIVERSALK9-M), Version 15.0(1)M1, RELEASE SOFTWARE (fc1) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2009 by Cisco Systems, Inc. Compiled Wed 02-Dec-09 17:17 by prod_rel_team !--- output truncated Additional information about Cisco IOS Software release naming conventions is available in "White Paper: Cisco IOS and NX-OS Software Reference Guide" at: http://www.cisco.com/web/about/security/intelligence/ios-ref.html Products Confirmed Not Vulnerable +-------------------------------- Cisco IOS-XR is not affected by this vulnerability. No other Cisco products are currently known to be affected by this vulnerability. Details ======= Secure Shell (SSH) is a protocol which provides a secure remote access connection to network devices. The SSH server implementation in Cisco IOS Software and Cisco IOS XE Software contains a DoS vulnerability in the SSH version 2 (SSHv2) feature that could allow an unauthenticated remote attacker to cause a device to reload. An attacker could exploit this vulnerability by attempting a reverse SSH login with a crafted username. Successful exploitation of this vulnerability could allow an attacker to create a DoS condition by causing the device to reload. Repeated exploits could create a sustained DoS condition. The SSH server in Cisco IOS Software and Cisco IOS XE Software is an optional service, but its use is highly recommended as a security best practice for management of Cisco IOS devices. SSH can be configured as part of the AutoSecure feature in the initial configuration of IOS devices, AutoSecure run after initial configuration, or manually. SSH is enabled any time RSA keys are generated such as when an http secure-server or trust points for digital certificates are configured. Devices that are not configured to accept SSHv2 connections are not affected by this vulnerability. A complete TCP three-way handshake is required to exploit this vulnerability. Reverse SSH traffic uses TCP port 22 by default. This vulnerability has been documented in Cisco Bug ID CSCtr49064 and has been assigned the Common Vulnerabilities and Exposures (CVE) ID CVE-2012-0386. Vulnerability Scoring Details ============================= Cisco has scored the vulnerability in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this security advisory is in accordance with CVSS version 2.0. CVSS is a standards-based scoring method that conveys vulnerability severity and helps organizations determine the urgency and priority of a response. Cisco has provided a base and temporal score. Customers can also compute environmental scores that help determine the impact of the vulnerability in their own networks. Cisco has provided additional information regarding CVSS at the following link: http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to compute the environmental impact for individual networks at the following link: http://intellishield.cisco.com/security/alertmanager/cvss * CSCtr49064 - Cisco IOS Software Reverse SSH Denial of Service CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of this vulnerability could allow an unauthenticated, remote attacker to create a DoS condition by causing the device to reload. Repeated exploits could create a sustained DoS condition. Software Versions and Fixes =========================== When considering software upgrades, customers are advised to consult the Cisco Security Advisories and Responses archive at: http://www.cisco.com/go/psirt and review subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers. Cisco IOS Software +----------------- Each row of the following Cisco IOS Software table corresponds to a Cisco IOS Software train. If a particular train is vulnerable, the earliest releases that contain the fix are listed in the First Fixed Release column.

Cisco IOS XR Software +-------------------- Cisco IOS XR Software is not affected by any of the vulnerabilities disclosed in the March 2012 Cisco IOS Software Security Advisory Bundled Publication. Workarounds =========== If disabling the IOS SSH Server is not feasible, the following workarounds may be useful to some customers in their environments. SSH version 1 +------------ This vulnerability only affects SSHv2, so it can be temporarily mitigated by applying the ip ssh version 1 global configuration command until a software update can be completed. Customers should be aware of the limitations and vulnerabilities of SSH version 1 protocol before applying this workaround. vty Access Class +--------------- It is possible to limit the exposure of the Cisco device by applying a vty access class to allow only known, trusted hosts to connect to the device via SSH. For more information on restricting traffic to a vty, please consult: http://www.cisco.com/en/US/docs/ios/12_2/ipaddr/command/reference/1rfip1.ht… The following example permits access to the vty lines from the 192.168.1.0/24 netblock and the single IP address 172.16.1.2 while denying access from anywhere else: Router(config)# access-list 1 permit 192.168.1.0 0.0.0.255 Router(config)# access-list 1 permit host 172.16.1.2 Router(config)# line vty 0 4 Router(config-line)# access-class 1 in Different Cisco platforms support a different amount of terminal lines. Check your device's configuration to determine the correct number of terminal lines for your platform. Infrastructure Access Control Lists +---------------------------------- Although it is often difficult to block traffic transiting your network, it is possible to identify traffic that should never be allowed to target your infrastructure devices and block that traffic at the border of your network. Infrastructure access control lists (iACLs) are considered a network security best practice and should be considered as a long-term addition to good network security as well as a workaround for this specific vulnerability. The ACL example shown below should be included as part of the deployed infrastructure access-list, which will protect all devices with IP addresses in the infrastructure IP address range. A sample access list for devices running Cisco IOS is below: !--- Permit SSH services from trusted hosts destined !--- to infrastructure addresses. access-list 150 permit tcp TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK eq 22 !--- Deny SSH packets from all other sources destined to infrastructure addresses. access-list 150 deny tcp any INFRASTRUCTURE_ADDRESSES MASK eq 22 !--- Permit all other traffic to transit the device. access-list 150 permit IP any any interface serial 2/0 ip access-group 150 in The white paper titled "Protecting Your Core: Infrastructure Protection Access Control Lists" presents guidelines and recommended deployment techniques for infrastructure protection access lists. This white paper is located at: http://www.cisco.com/en/US/tech/tk648/tk361/technologies_white_paper09186a0… Control Plane Policing +--------------------- The Control Plane Policing (CoPP) feature may be used to mitigate these vulnerabilities. In the following example, only SSH traffic from trusted hosts with receive destination IP addresses is permitted to reach the route processor (RP). Note: Dropping traffic from unknown or untrusted IP addresses may affect hosts with dynamically assigned IP addresses from connecting to the Cisco IOS device. access-list 152 deny tcp TRUSTED_ADDRESSES MASK any eq 22 access-list 152 permit tcp any any eq 22 ! class-map match-all COPP-KNOWN-UNDESIRABLE match access-group 152 ! ! policy-map COPP-INPUT-POLICY class COPP-KNOWN-UNDESIRABLE drop ! control-plane service-policy input COPP-INPUT-POLICY In the above CoPP example, the ACL entries that match the exploit packets with the permit action result in these packets being discarded by the policy-map drop function, while packets that match the deny action are not affected by the policy-map drop function. Additional information on the configuration and use of the CoPP feature can be found at the following URL: http://www.cisco.com/en/US/prod/collateral/iosswrel/ps6537/ps6586/ps6642/pr… Obtaining Fixed Software ======================== Cisco has released free software updates that address the vulnerability described in this advisory.

The vulnerability is triggered when an affected device processes a malformed Smart Install message on TCP port 4786. Cisco has released free software updates that address this vulnerability. There are no workarounds to mitigate this vulnerability. This advisory is available at the following link: http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-… Note: The March 28, 2012, Cisco IOS Software Security Advisory bundled publication includes nine Cisco Security Advisories. Each advisory lists the Cisco IOS Software releases that correct the vulnerability or vulnerabilities detailed in the advisory as well as the Cisco IOS Software releases that correct all vulnerabilities in the March 2012 bundled publication. Individual publication links are in "Cisco Event Response: Semi-Annual Cisco IOS Software Security Advisory Bundled Publication" at the following link: http://www.cisco.com/web/about/security/intelligence/Cisco_ERP_mar12.html Affected Products ================= Vulnerable Products +------------------ Devices configured as a Smart Install client or director are affected by this vulnerability. To display Smart Install information, use the show vstack config privileged EXEC command on the Smart Install director or client. The outputs of show commands are different when entered on the director or on the client. The following is the output of show vstack config in a Cisco Catalyst Switch configured as a Smart Install client: switch#show vstack config Role: Client Vstack Director IP address: 10.1.1.163 The following is the output of show vstack config in a Cisco Catalyst Switch configured as a Smart Install director: Director# show vstack config Role: Director Vstack Director IP address: 10.1.1.163 Vstack Mode: Basic Vstack default management vlan: 1 Vstack management Vlans: none Vstack Config file: tftp://10.1.1.100/default-config.txt Vstack Image file: tftp://10.1.1.100/c3750e-universalk9-tar.122- Join Window Details: Window: Open (default) Operation Mode: auto (default) Vstack Backup Details: Mode: On (default) Repository: flash:/vstack (default) The Smart Install Feature is enabled by default. To determine the Cisco IOS Software release that is running on a Cisco product, administrators can log in to the device and issue the show version command to display the system banner. The system banner confirms that the device is running Cisco IOS Software by displaying text similar to "Cisco Internetwork Operating System Software" or "Cisco IOS Software." The image name displays in parentheses, followed by "Version" and the Cisco IOS Software release name. Other Cisco devices do not have the show version command or may provide different output.

however, this product reached the End of Software Maintenance milestone. Cisco 3550 Series SMI Switches that are running Layer 2 images do not support IKE and are not vulnerable. No other Cisco devices that run 12.2SE-based software are vulnerable. Cisco IOS XE Software +-------------------- Cisco IOS XE Software is not affected by the vulnerability disclosed in this advisory. Cisco IOS XR Software +-------------------- Cisco IOS XR Software is not affected by any of the vulnerabilities disclosed in the March 2012 Cisco IOS Software Security Advisory Bundled Publication. Workarounds =========== There are no workarounds available to mitigate this vulnerability other than disabling the Smart Install feature. To disable the Smart Install feature use the global configuration command no vstack. Additional mitigations that can be deployed on Cisco devices within the network are available in the Cisco Applied Mitigation Bulletin companion document for this advisory, which is available at the following link: http://tools.cisco.com/security/center/content/CiscoAppliedMitigationBullet… Obtaining Fixed Software ======================== Cisco has released free software updates that address the vulnerability described in this advisory. Prior to deploying software, customers are advised to consult their maintenance providers or check the software for feature set compatibility and known issues that are specific to their environments. Customers may only install and expect support for feature sets they have purchased. By installing, downloading, accessing, or otherwise using such software upgrades, customers agree to follow the terms of the Cisco software license at: http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html or as set forth at http://www.cisco.com/public/sw-center/sw-usingswc.shtml Do not contact psirt(a)cisco.com or security-alert(a)cisco.com for software upgrades. Customers with Service Contracts +------------------------------- Customers with contracts should obtain upgraded software through their regular update channels. For most customers, upgrades should be obtained through the Software Center on Cisco.com at: http://www.cisco.com Customers Using Third-Party Support Organizations +------------------------------------------------ Customers with Cisco products that are provided or maintained through prior or existing agreements with third-party support organizations, such as Cisco Partners, authorized resellers, or service providers, should contact that organization for assistance with the appropriate course of action. The effectiveness of any workaround or fix depends on specific customer situations, such as product mix, network topology, traffic behavior, and organizational mission. Because of the variety of affected products and releases, customers should consult their service providers or support organizations to ensure that any applied workaround or fix is the most appropriate in the intended network before it is deployed. Customers Without Service Contracts +---------------------------------- Customers who purchase directly from Cisco but do not hold a Cisco service contract and customers who make purchases through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should obtain upgrades by contacting the Cisco Technical Assistance Center (TAC): * +1 800 553 2447 (toll free from within North America) * +1 408 526 7209 (toll call from anywhere in the world) * e-mail: tac(a)cisco.com Customers should have the product serial number available and be prepared to provide the URL of this advisory as evidence of entitlement to a free upgrade. Customers without service contracts should request free upgrades through the TAC.

RPKI support from router verndors
by Carlos Martinez-Cagnazzo 28 Mar '12

28 Mar '12

Hello all, I was wondering when can we actually expect RPKI / origin validation support from router vendors. I know where Cisco and Juniper stand, in fact, I have been testing both implementations. So, I would like to know if some one has heard anything from: - Huawei - Alcatel - Others ? regards Carlos

I have three plants in China and China Telecom loves batting down our VPN tunnels. They've left the current solution alone for a few months now. It appears they try to do DPI on SSL/IPSec to see if it's a VPN tunnel. I placed our SSL OpenVPN tunnel inside of a GRE tunnel. For some reason, they don't seem to be doing DPI on it and mostly leave it alone now. I'm sure it'll change at some point soon, though. -- Thomas York -----Original Message----- From: TR Shaw [mailto:tshaw@oitc.com] Sent: Tuesday, March 27, 2012 10:45 AM To: Jim Gonzalez Cc: nanog(a)nanog.org Subject: Re: OWA blocked by China On Mar 27, 2012, at 10:16 AM, Jim Gonzalez wrote: > Hello, > > One of my customers has workers in China.

The ILEC lobbyists are very influential and want to maintain the status quo at all costs. A lot of the examples you listed are pilot projects that providers do mostly for PR purposes so they can say "we provide FTTH" with a "* in select areas" footnote. They rarely see any large scale adoption and are usually operated at a loss. I think the key problem is that building out fiber doesn't make business sense if each provider in an area has to build out identical infrastructure and doesn't have the safety of a monopoly. As mentioned, providers are also concerned with the time it will take to realize ROI. The result is that we need to subsidize this infrastructure if we want it, but we end up with no competition and poor service if the service provider is the one getting those subsidies. Aside from very urban areas where the density can support the investment, the only solution becomes to create an open access public utility to maintain the fiber plant, cans, huts, etc. and prohibit them from offering any lit services over that fiber. As for rural areas not needing broadband; I think it's a matter of national interest that everyone has access to broadband. Just like power. When we make an effort to lift everyone up, we all do better. The Internet, like the Interstate highway system, is a time machine. It shortens distances between people and makes us more productive. Even better, it allows businesses to locate anywhere.

Maybe, but, if what is happening now is allowed to continue, it will: 1. Not encourage competition anywhere. 2. Allow existing monopolies to preserve and extend those monopolies. 3. Cost even more than it already has. 4. Continue to lag behind the rest of the world. 5. Result in an inferior solution. What is needed is for regulators to step up with a bold vision for the public good. We need to encourage (or even require) local authorities to deploy (themselves or by contract) independent L1 infrastructure (yes, I like the 4-8 strands per residence star topology idea) to every structure within their jurisdiction and make it available to L2+ service providers on an equal-cost-per-subscriber basis in each jurisdiction. Yes, this means that the cost per subscriber will be lower in denser jurisdictions than it will be in less dense jurisdictions. However, users in those jurisdictions should expect to pay more for services and the ability to attract L2+ service providers can be achieved in a variety of ways. The important thing is to make sure that if public money is being used to build infrastructure, it becomes infrastructure that is useful to said public and not just a subsidy to some corporation for extending its monopoly in a manner that is often contrary to the public good. Unfortunately, that is exactly where the money is going today.

$1.5 billion: The cost of cutting London-Tokyo latency by 60ms
by Eugen Leitl 26 Mar '12

http://www.extremetech.com/extreme/122989-1-5-billion-the-cost-of-cutting-l… $1.5 billion: The cost of cutting London-Tokyo latency by 60ms By Sebastian Anthony on March 20, 2012 at 1:04 pm Arctic Link submarine cable Starting this summer, a convoy of ice breakers and specially-adapted polar ice-rated cable laying ships will begin to lay the first ever trans-Arctic Ocean submarine fiber optic cables. Two of these cables, called Artic Fibre and Arctic Link, will cross the Northwest Passage which runs through the Canadian Arctic Archipelago. A third cable, the Russian Optical Trans-Arctic Submarine Cable System (ROTACS), will skirt the north coast of Scandinavia and Russia. All three cables will connect the United Kingdom to Japan, with a smattering of branches that will provide high-speed internet access to a handful of Arctic Circle communities. The completed cables are estimated to cost between $600 million and $1.5 billion each. All three cables are being laid for the same reasons: Redundancy and speed. As it stands, it takes roughly 230 milliseconds for a packet to go from London to Tokyo; the new cables will reduce this by 30% to 170ms. This speed-up will be gained by virtue of a much shorter run: Currently, packets from the UK to Japan either have to traverse Europe, the Middle East, and the Indian Ocean, or the Atlantic, US, and Pacific, both routes racking up around 15,000 miles in the process. It’s only 10,000 miles (16,000km) across the Arctic Ocean, and you don’t have to mess around with any land crossings, either. Russian Optical Trans-Arctic Submarine Cable System (ROTACS) between UK and JapanThe massive drop in latency is expected to supercharge algorithmic stock market trading, where a difference of a few milliseconds can gain (or lose) millions of dollars. It is for this reason that a new cable is currently being laid between the UK and US — it will cost $300 million and shave “just” six milliseconds off the fastest link currently available. The lower latency will also be a boon to other technologies that hinge heavily on the internet, such as telemedicine (and teleconferencing) and education. Telephone calls and live news coverage would also enjoy the significantly lower latency. Each of the fiber optic cables will have a capacity in the terabits-per-second range, which will probably come in handy too. Beyond the stock markets, though, the main advantage of the three new cables is added redundancy. Currently, almost every cable that lands in Asia goes through a choke point in the Middle East or the Luzon Strait between the Philippine and South China seas. If a ship were to drag an anchor across the wrong patch of seabed, billions of people could wake up to find themselves either completely disconnected from the internet or surfing with dial-up-like speeds. The three new cables will all come down from the north of Japan, through the relatively-empty Bering Sea — and the Arctic Ocean, where each of the cables will run for more than 5,000 miles, is one of the least-trafficked parts of the world. That said, the cables will still have to be laid hundreds of meters below the surface to avoid the tails of roving icebergs. The ROTACS cable path Each cable will be laid by a pair of ships: an ice breaker that leads the way, and a cable ship. Until now it has been impossible to lay cables in the Arctic Ocean, but the retreat of the Arctic sea ice means that the Northwest Passage is now generally ice-free from August to October; a big enough window that cable can be laid fairly safely. Existing cable ships (and there aren’t many of them) are all outfitted for balmier climes, so all three cables will require the use of a polar ice-rated ship that has been retrofitted to carry cable-laying gear.
