RE: high latency ds3 issue on unloaded line
by prue 26 Sep '08

26 Sep '08

I am wondering if the packets might be MD5 packets addressed to your router. They might be small with no valid content but your router gets busy validating the MD5 sum for each packet before the router then drops the packet. That keeps the router busy doing nothing useful. Did you check your CPU utilization during the high latency periods then check to see which process is consuming the CPU cycles if it does look high? Walt

L3 route flapping
by Justin Shore 26 Sep '08

26 Sep '08

Is anyone else seeing 72.237.248.0/22 flapping? As of about 10 minutes ago Oregon-IX reported that it had flapped 8 times in 50 minutes. We have a production phone system on that network that's going crazy. Thanks Justin

Internet Filtering Lobby ?
by Marshall Eubanks 26 Sep '08

26 Sep '08

Does anyone know what this group is really about and how it might actually impact real networks ? Regards Marshall http://www.artsandlabs.com/ http://blog.wired.com/27bstroke6/2008/09/entertainment-l.html Behind the lobby are AT&T, Cisco Systems, Microsoft, NBC Universal, Viacom and the Songwriters Guild of America. Among other things, the lobby, calledArts+Labs, says "network operators must have the flexibility to manage and expand their networks to defend against net pollution and illegal file-trafficking which threatens to congest and delay the network for all consumers."

ARIN Routing Registry vs RADB vs X
by Craig Holland 26 Sep '08

26 Sep '08

Hi, I recently ran across a situation where a large ISP only accepts IRR entries generated by RADB to build their path filters. I use the ARIN Routing Registry. Is this a common practice? Should I convert over to RADB? Thanks, Craig
