New IPv4 blocks allocated to RIPE NCC
by Alex Le Heux 29 Mar '07

29 Mar '07

[Apologies for duplicate mails] Dear Colleagues, The RIPE NCC received the IPv4 address ranges 92/8 and 93/8 from the IANA in March 2007. We will begin allocating from these ranges in the near future. The minimum allocation size for these two /8s has been set at /21. You may wish to adjust any filters you have in place accordingly. More information on the IP space administered by the RIPE NCC can be found on our web site at: <https://www.ripe.net/ripe/docs/ripe-ncc-managed-address-space.html> Additionally, please note that two "pilot" prefixes will be announced from each /8. The prefixes are: 92.192.0.0/16 93.192.0.0/16 92.255.248.0/21 93.255.248.0/21 They all originate in AS12654. More information on this "pilot" activity is available in the draft document "De-Bogonising New Address Blocks" which can be found at: <http://www.ripe.net/ripe/draft-documents/deboganising-draft.html> Best regards, Alex Le Heux RIPE NCC IP Resource Analyst

Re: TCP and WAN issue
by Robert Boyle 29 Mar '07

29 Mar '07

A lot of different theoretical things have been discussed, but basically, if you are running Windows XP, 2000, or 2003 over a WAN with anything more than 10-20ms of latency, make the following change to the registry and you will find a world of difference. Ideally, you would make the change to both sides, but as long as one side has this, it will auto-negotiate with the other side to adjust the Start, Run, regedt32 Go to: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters Edit, New -> DWORD Value Then name it "Tcp1323Opts" (without the quotes) and change the value to 3 That will give you far better performance by enabling automatic TCP window size scaling as per RFC 1323 over your WAN links (hence the key name), but only to other computers which support RFC1323. XP and 2003 default to allowing scalable windows if the far side intiates the negotiation, but that will never happen unless one side has this key set. Values are: 0 (disable RFC 1323 options) - default before creating the key 1 (window scale enabled only) 2 (timestamps enabled only) 3 (both options enabled) Try this and let us know what you see. -Robert Tellurian Networks - Global Hosting Solutions Since 1995 http://www.tellurian.com | 888-TELLURIAN | 973-300-9211 "Well done is better than well said." - Benjamin Franklin

ICMP unreachables, code 9,10,13
by Christos Papadopoulos 28 Mar '07

28 Mar '07

First, let me thank everyone who responded to my previous question about routers prioritizing control traffic, your comments were much appreciated. My next question is about responses to ICMP pings (echo request), when they return ICMP UNREACHABLE with codes 9,10 or 13. These codes are defined as follows: unreachable 9 Communication with Destination Network is Administratively Prohibited unreachable 10 Communication with Destination Host is Administratively Prohibited unreachable 13 Communication Administratively Prohibited - generated if a router cannot forward a packet due to administrative filtering Responses with these codes seem to imply the presence of a firewall. Is this assumption correct or are these codes meaningless? If this a configurable parameter, how to you typically decide what to set it to? Thanks! Christos Papadopoulos Colorado State University

Re: TCP and WAN issue
by Philip Lavine 27 Mar '07

27 Mar '07

This is the exact issue. I can only get between 5-7 Mbps. So the question is really what incremental performance gain do WAN accelerators/optimizers offer? Can registry/OS tweaks really make a significant difference because so far with all the "speed enhancements" I have deployed to the registry based on the some of the aforementioned sites I have seen no improvement. I guess I am looking for a product that as a wrapper can multiplex a single socket connection.

You will have problems obtaining anything more than 5-7Mbit/s based on 1500 byte Ethernet packets and a RTT latency of 70-90ms. You can increase your window size or use Jumbo Ethernet frames. Almost all GigE gear supports jumbo frames. I'm not sure of your application, but without OS tweaks, each stream is limited to 5-7Mbit/s. You can open multiple streams between the same two hosts or you can use multiple hosts to transfer your data. You can utilize the entire DS3, but not without OS TCP stack tweaks or a move to jumbo frames. You can also use UDP or another connectionless packet method to move the data between sites. Good luck. -Robert Tellurian Networks - Global Hosting Solutions Since 1995 http://www.tellurian.com | 888-TELLURIAN | 973-300-9211 "Well done is better than well said." - Benjamin Franklin ____________________________________________________________________________________ Finding fabulous fares is fun.
