I am not sure that this answers your question, but carriers are looking for more diversity on cross border traffic. Right now virtually all Toronto/NYC runs through Buffalo and 350 Main, Buffalo. May be Montreal/NYC has more options. There have been huge network builds in the US Northeast by Unite and Firstlight, which are providing optical backhaul from cell towers. So more routing options may be available than in the past. An issue that no one discussed in the age of the fiber. The big carriers and the Web Giants do not want to 1998 manufactured fiber. And some of the Web Giants are only putting 4x 100 gig waves per fiber pair. So the incentive to create new diverse routes with new large fiber builds is growing. - R. ________________________________ From: NANOG <nanog-bounces () nanog org> on behalf of Constantine A.

Hi, We're looking to extend some services into Canada. While our lawyers dig into it, I thought that I'd ask the hive mind about border restrictions. For traffic routing, is anyone constraining cross-border routing between Canada and the US? IOW, if you are routing from Toronto to Montreal, do you have to guarantee that the path cannot go through, say, Syracuse, New York?
Guarantee to whom? Back a few years ago when I looked into it, most of the traffic within Canada went through the US, e.g., since Bell didn't want to peer with anyone in Canada, you'd go something like YYZ - ORD - YYZ, clearly visible through the traceroute. Possibly somewhat better nowadays — there's been quite a few new IX POPs that popped up — but I doubt the scenario is a thing of the past. P.S. Just for the giggles — checked http://lg.he.net/ routing from Looking Glass - Hurricane Electric (AS6939)<http://lg.he.net/> lg.he.net Hurricane Electric (AS6939) Network Looking Glass core1.tor1.he.net to www.bell.ca<http://www.bell.ca> — still goes through Chicago, to [http://upload.wikimedia.org/wikipedia/commons/thumb/9/91/Bell_logo.svg/120px-Bell_logo.svg.png]<http://www.bell.ca/> Bell Canada - Mobile phones, TV, Internet and Home phone ...<http://www.bell.ca/> www.bell.ca Bell is Canada's largest telecommunications company, providing Mobile phone, TV, high speed and wireless Internet, and residential Home phone services.

P.P.S. In other words — if someone wants guarantees, they better explicitly ask you for it.
