[c-nsp] new Cisco routers 1800/2800/3800

[Church, Chuck]

It must be a hell of a CPU then.  That Miercom report listed 550Mb full duplex for the 3845, with NAT and I assume CBAC in use.   Granted it's huge packets, but still, that's almost 95,000 pps at almost full size.  I don't think the 3745 can touch that.  That's NPE-400 territory, isn't it?  I imagine that NPE-G2 coming out soon ought to be a beast!

No, CPU is still doing routing etc. Only the buses changed from simple
PCI ones to dedicated-ASIC based. The firewall (ACLs/statefull firewall)
is also software-based not hardware based. However, it's true there's
internal simple VPN ASIC on-board, that usually can serve up to 500-700
tunnels (but the AIM slot is ready for dedicated AIM module, which
if installed, enhances throughput and maximum number of the VPN
tunnels). Also, there's internal TDM functionality on-board, so You can
start mixing DS0 channels from various interface cards without any
special considerations and specific module cards.

Most of this information is already available on the cisco.com/go/isr
site, with presentations and technical specs.
