Hi guys/gals, For a certain operation, we will be ordering a STM4c circuit. The edge router (our side) is a Cisco 7507, running RSP8, with VIP4-80s. I saw that Cisco havea PA-OC12 card for the 750x series. My questions is as follows: This particular location is an Internet exchange. Traffic can be classified as general purpose, and I assume web access is the largest share of it. I heard of different limitations of the VIP4-80, as per how many pps it can do, and what my boss heard from Cisco was about 400Mbit/s worth of packets (if we take the usual packet size distribution into consideration). I wonder if this is true. AFAIK, there are PA-GE cards for 750x series too. Would they also be stuck at ~40% of their potential ? For that OC12 card, this makes it roughly 500Mb/s worth of cells (tax this for packet to cell conv. and you're at 400Mbit/s). Does any of you run STM4c circuits on 750x routers (not 12k or Junipers) ? If you do, have you ever came close to the full capacity of the link ? I need to know this before I order it (although this is more academic than anything else, since I have no choice in the matter anyway). thanks for you input, --Ariel -- Ariel Biener e-mail: ariel@post.tau.ac.il PGP(6.5.8) public key http://www.tau.ac.il/~ariel/pgp.html
