RB1100AH or 1100AHx2 vs Cisco NPE-G1

Mon May 21, 2012 1:25 am

Its time to update some of our Internet edges. Right now, its the small packets (SIP/RTP) that are killing our existing Cisco 7200VXR routers with the NPE-400. While I could take the easy way out and spend mucho dollars and get the NPE-G1 engine for them ... but the RB1100AHx2 looks sexy as all get out. How it match up against the Cisco NPE-G1?

The router would need to handle 2 filtered BGP feeds (about 150K routes total), with those feeds are doing about 40- 50Mb (on this particular edge). Some QoS mangling, but no other fire walling or NAT.

Thoughts? Specs of the X2 look great - just looking for some real-world results.

Why do you talk about small packets killing the router and then you present a figure in Mb?

What is the pps figure, because as you've said, that is the killer?

At 40Mbit, having 160bytes RTP payload with ethernet/ip/udp overhead that is 25kpps. Is that correct?
Bi-directional that means 50kpps total.

Worst case scenario for AHx2 is 243000pps.

I successfully replace 7200VXR-NPE-G1 by 1100AHx2 at 1333MHz...with several bgp feed with 400K routes...on Gigabit connection...load 30% cpu at 300Mbits
