Sprint has probably the lowest latency in the industry; I use them for a Los Angeles - London IPSec VPN. Typical latency is around 140-150 ms rt (70-75 ms one-way) 40 ms RT is not possible in this reality, unless the speed of light is increased or one transimits through subspace (see Star Trek) -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Neal R Sent: Thursday, June 28, 2007 4:21 PM To: [email protected] Subject: trans-Atlantic latency? I have a customer with IP transport from Sprint and McLeod and fiber connectivity to Sprint in the Chicago area. The person making the decisions is not a routing guy but is very sharp overall. He is currently examining the latency on trans-Atlantic links and has fixed on the idea that he needs 40ms or less to London through whatever carrier he picks. He has spoken to someone at Cogent about a point to point link. What is a reasonable latency to see on a link of that distance? I get the impression he is shopping for something that involves dilithium crystal powered negative latency inducers, wormhole technology, or an ethernet to tachyon bridge, but its been a long time (9/14/2001, to be exact) since I've had a trans-Atlantic circuit under my care and things were different back then. Anyone care to enlighten me on what these guys can reasonably expect on such a link? My best guess is he'd like service from Colt based on the type of customer he is trying to reach, but its a big muddle and I don't get to talk to all of the players ... -- This mail was scanned by BitDefender For more informations please visit http://www.bitdefender.com -- This mail was scanned by BitDefender For more informations please visit http://www.bitdefender.com
