Michael, A few questions:
1. I see you mention 225Mbps, but what is the packet-per-second rate? This is actually a more important factor, as router performance is usually PPS-rate based 2. Is 225M the total hub rate, or is it per spoke? In general, I would suggest getting the HW encryption option (VAM in the 7200 case) as it would provide a more deterministic latency as encryption would be done in dedicated HW.

The WAN in question is Cogent's ethernet service - built as a mesh of point-to-point VLANs. There are 3 sites, at every site I have a single port over which I receive 2 VLANs in a dot1q trunk. Aggregate bandwidth on the port is 200Mbps. Putting in encryption seems fairly straightforward - 3 static IPSEC tunnels. I am trying to figure out what kind of hardware can handle IPSEC at this bandwidth. So far I am looking at: -ASA5520. Specs say 225Mb of IPSEC - can the box actually handle that, or should I be looking at 5540? -7201 (or 7206) with NPEG2. Do I need to add a VAM, or will the NPE handle the load? Any real-world experiences will be most appreciated. Also, if there are better suggestions (including non-Cisco), please share.
