On the topic of building a software router for an ISP, has anyone tried it
using OpenFlow? The idea is to have a Linux server run BGP and a hardware
switch to move the packets. The switch would be programmed by the Linux
server using the OpenFlow protocol.
I am looking at the HP 5400 zl switches as the hardware platform and
RouteFlow https://sites.google.com/site/routeflow/ to program the BGP rules.
One issue is that the HP switch will only allow a limited amount of rules
to be processed in hardware (about 4096 rules I believe). Will this be
enough to cover most of the traffic of a FTTH ISP on the fast path?
