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?
You want to use the switch for what ? To connect last-mile customers ? For L3 aggregation ? You want to run the switch as an edge router with limited BGP ? What's the exact use case you are thinking about ? Eugeniu
