3DES VPN encryption speeds

Does anybody know if there is any Cisco documentation that maps out what the maximum 3des encryption speeds are per router.

I am looking specifically for the Cisco2621 router without the AIM card.

Thanks

Hi Patrick,

The peroformance numbers without the AIM Cards are hard to get as the Processor is running other operations at the same time and would not be a hard number just for the VPN performance/throughput. The numbers with the AIM Card can be seen at: http://www.cisco.com/en/US/products/hw/routers/ps259/products_data_sheet09186a0080088750.html

Additionally, you should contact your local Cisco SE or the Account team to get any performance numbers, they should be able to provide you with those.

Thanks,

Patrick,

An estimate from the following document, vpn_srnd.pdf, says 520 Kbps for the 2621 without the AIM. This is based on 65% CPU utilization, mixed packet sizes with 2 IPSEC/GRE tunnels. I would post the hyperlink, but I cannot remember the URL. If you like, reply to this post and I can email you the copy that I have.
