Specs are only as good as the entity providing the data. I can tell you a few stories about specs and some MAJOR fails by a major network equipment manufacturer failing to meet advertised specs. When you engage the engineering folks to assist in a build, they should know the true specs of their gear better than anyone else. If they say for a certain distance that A+B will work, then that is exactly what I expect. That is pretty basic.

[OT]call for backers: open source hardware for networking innovation (ONetSwitch)
by huc＠ieee 07 Apr '15

07 Apr '15

Sorry for a little bit off topic. This email is to inform you a new open source hardware for networking innovation called ONetSwitch. It is an all-programmable networking platform combining ARM and FPGA in a 17cm*13cm area (notebook size) for testing and verifying research idea related to networking. Different from previous FPGA develop board like NetFPGA/Xilinx PCIe board, host PC is not required any more for ONetSwitch, and it is smaller, cheaper, and more power efficient. and more flexible. We have launched the ONetSwitch project on Kickstarter.com weeks ago. You can get an abstract from the short video, which will not take you long to get our idea :-) https://www.kickstarter.com/projects/onetswitch/onetswitch-open-source-hard… We had a paper at ONS 2014 presenting the preliminary design of ONetSwitch (https://www.usenix.org/system/files/conference/ons2014/ons2014-paper-hu_che…) and a demo at SIGCOMM'14 setting a data center testbed on only desktop using ONetSwitch (http://nskeylab.xjtu.edu.cn/people/huc/Pub/DesktopDC_2014.pdf) In the new version now at kickstarter, we add further physical support on 802.11 AC, mSATA, which suits for more scenarios. Also, we have open source ref. design and supporting wiki available at github (https://github.com/MeshSr/wiki/wiki/REF-OpenFlowSwitch-HWFT) The processing logic can be modified in both software (ARM) and hardware (FPGA) to fit your own needs. Although it is currently highlighted mainly on SDN and DCN, we aim to provide the research community a way to set their testbeds for any networking innovations easily. I send the info. about ONetSwitch to this mail list since I think it may be useful to guys in this community. Please do us a favor and back us to get your own programmable testbed. We believe ONetSwitch would give much help to your research and development work. Also, can you help distribute it to friends and colleagues who will be interested with this? Even for the guys, who do not need ONetSwitch but think it is good, we greatly appreciate you to back us with $1 for encouraging.

Usage data from Turkey
by Mehmet Akcin 06 Apr '15

06 Apr '15

Hello Today March 31 , 2015 GMT +0200 1030am-4pm Turkey has suffered a major power outage impacting nearly 70M people. I am writing a blog post about power outage vs impact to network usage. I am looking for as much as useful network usage information possible related to Turkey. If you can share network usage information, i will be making sure to buy you some drinks at next nanog ;) Cheers Mehmet

Denver
by Mike Hammett 02 Apr '15

02 Apr '15

So in Denver Comfluent\CoreSite seems to be the place to be... except as someone that predominately serves eyeball networks, I'm interested in NetFlix. NetFlix is in EdgeConneX... where no other significant peering is happening. Also, my partner who has been looking into the Denver market said that CoreSite costs more than Chicago Equinix. Any recommendations for where to go? Seems like both main options suck, but there aren't any better. This would be for eyeball networks getting peering with the big content guys and cheaper transit than the tier 4\5\6\7\8 (how small of markets get numbers?) where they're located. Any significant web hosting operations in the Denver market? Someone that's bigger than "Bob's DS3 Web Hosting", but not SoftLayer size where they can't get creative with their services. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com

How are you doing DHCPv6 ?
by Randy Carpenter 02 Apr '15

02 Apr '15

I am wondering how people out there are using DHCPv6 to handle assigning prefixes to end users. We have a requirement for it to be a redundant server that is centrally located. DHCPv6 will be relayed from each customer access segment. We have been looking at using ISC dhcpd, as that is what we use for v4. However, it currently does not support any redundancy. It also does not do very much useful logging for DHCPv6 requests. Certainly not enough to keep track of users and devices. So, my questions are: How are you doing DHCPv6 with Prefix Delegation? What software are you using? When DHCPv6 with Prefix Delegation seems to be about the only way to deploy IPv6 to end users in a generic device-agnostic fashion, I am wondering why it is so difficult to find a working solution. thanks, -Randy -- | Randy Carpenter | Vice President - IT Services | Red Hat Certified Engineer | First Network Group, Inc. | (800)578-6381, Opt. 1 ----

Broken SSL cert caused by router?
by Mike 30 Mar '15

30 Mar '15

Hi, I have a very odd problem. We've recently gotten a 'real' ssl certificate from godaddy to cover our domain (*.domain.com) and have installed it in several places where needed for email (imap/starttls and etc) and web. This works great, seems ok according to various online TLS certificate checkers, and I get the green lock when testing using my own browsers and such. I have a customer however that uses our web mail system now secured with ssl. I myself and many others use it and get the green lock. But, whenever any station at the customer tries using it, they get a broken lock and 'your connection is not private'. The actual error displayed below is 'cert_authority_invalid' and it's "Go Daddy Secure Certificate Authority - G2". And it gets worse - whenever I go to the location and use my own laptop, the very one that 'works' when at my office, I ALSO get the error. AND EVEN WORSE - when I connect to my cell phone provided hotspot, the error goes away! As weird as this all sounds, I got it nailed down to one device - they have a Cisco/Meraki MX64W as their internet gateway - and when I remove that device from the chain and go 'straight' out to the internet, suddenly, the certificate problem goes away entirely. How is this possible? Can anyone comment on these devices and tell me what might be going on here? Mike-

IRRPT has been rewritten in Python but have not had time to play with. It includes IPv6 support. You probably have to modify it to output in XR's set format.

booster to gain distance above 60km
by Rodrigo Augusto 28 Mar '15

28 Mar '15

Hi folks we have a point and have a 63km between point A to point B. We have a sigle fiber ( only one fiber) and use a fiberstore sfp+ 10GB dibi 1270/1330 module to connect these sites. All attenuation are okI don¹t have any trouble on fiber . I have received this signal on my sfp+: Receiver signal average optical power : 0.0026 mW / -25.85 dBm Does anyone know if have some possible to amplifier this scenario to get more 7db ? Is it possible to put any booster or any way to solve this? I think to use a optical PreAmlifierbut I don¹t know if is possible because my scenario have just one fiberor, use a ROPA- remote optical pumping amplifier) because I have 63km Does anyone have some idea?
