RP1 is much slower then RP2. RP2 is AFAIK a 64bit Celleron-based platform, and RP1 some sort of RISC-based 32bit. Both ESP and SIP throughput is only 'used' one way, so ESP20 can take up to 20G of input traffic and process it fine. NAT throughput for the ESPs looks roughly like this: ESP10: 6Mpps Nat sessions max: 1M session setup rate: 100kcps Nat throughput: 10Gbs ESP20: 8Mpps Nat sessions max: 2M session setup rate: 200kcps Nat throughput: 20Gbs ESP40: 9Mpps Nat sessions max: 2M session setup rate: 200kcps Nat throughput: 40Gbs with SIP cards you have to count both traffic entering from the interfaces and the backplane. If the numbers above are not big enought you might have to look at doing something with ASR9k and the ISM cards (http://www.cisco.com/en/US/prod/collateral/routers/ps9853/data_sheet_c78-663164.html). kind regards Pshem _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
