New Edge Brokenness?
by Jason Slagle 13 Dec '04

13 Dec '04

Has anyone else noticed an increase in layer 3 downtime in newedges network since the "big meltdown"? I'm now losing connectivity several times a day, and only layer 3. Attempts to go through the normal support channels have resulted in runarounds and layer one/two tests.

how could I find out the problem source on broadband connection?
by Thomas Graham 13 Dec '04

13 Dec '04

hey all, my connection is 10mbit VDSL line, during these two months, my upload speed to EU and US are very damn slow, average speed is around 7KBytes/sec, does anyone feel free to try to find out what's going on ? at first, I was suspect that problem might caused by GBLX, but after one of the engineer check the link, it seems not related with them, so I would like you guys to help a bit, please try to see what's going on, let me know if you found anything, I got a server for you guys for download a sample file so that you could track down the packet routing path: http://sml.dyndns.org/files/testmusic.mp3 Thans a lot all

Affects of rate-limiting at the far end of links
by Sam Stickland 13 Dec '04

13 Dec '04

Hi, Just a quicky. We've got leased line out to a remote site that's pretty much at capacity for remote to local site traffic, and from time to time it appears to lock up for periods of 30 seconds or more. Investigating it appears we outbound traffic shape, and ingress rate-limit at the 'local' end of the line, but nothing is done at the 'remote' end. The remote end is some 14ms away across a third party MPLS network. Obviously we need to shape at the remote end, but the current behaviour intrigues me. Rate-limiting, while bad compared to shaping, in my experience doesn't lock out traffic for such long periods of time. Could it be that buffers and flow-control over the 14ms third party leg are causing the rate-limiting leaky bucket to continue to overflow long after it's full? Sam

(newbie) BGP For Dummies?
by David E. Smith 12 Dec '04

12 Dec '04

"Hi, long-time listener, first-time caller..." Can anyone recommend a good forum for BGP questions? I've got my copy of the O'Reilly book handy, but having never really worked with BGP before, I find it's not really the best novice-level work. (Or, if questions about weird inter-AS routing scenarios are on-topic here, I'd be glad to bounce my problems around on NANOG.) Thanks! David Smith MVN.net
