[c-nsp] Real performance of 3DES traffic through 2821?

[Peter Olsson]

Hello!

By looking at Ciscos performance numbers for 2821, both
for unencrypted traffic and for encrypted traffic, we got
the impression that 2821 with AIM-VPN would be usable for
at least 60-70 Mbps of encrypted traffic. Then we had a
meeting with a company (not Cisco) that had actually tried
this in their lab. They said that 2821 with AIM-VPN/SSL-2 is
fine for encrypted traffic in the 20-30 Mbps range, not much
higher. I'm interested in other performance numbers for an
upcoming design decision.

Equipment recommendations for this scenario would be very much
appreciated:
Two central offices with 1 Gbps Ethernet between them.
Each central office has 100 Mbps Ethernet lines to 10-15 branch offices.
All traffic is encrypted.
We have been considering 2821 or 2851 at the branch offices,
and 7600 at the central offices.

Thanks!
