SDN White Paper Nuage Networks VSP – Delivers SDN in a Big Way

PPP-Logo-White-Papers-300x300.png

I wrote a white paper for Nuage Networks that is the first Packet Pushers White Paper. Nuage Networks have announced their version of SDN and I think it’s solid vision of what Software Defined Networking will become over the next couple of years – tunnel fabrics, software network agents in the server with load balancing and routing capabilities and controller/application software that can manage multiple data centres and their WAN networks.

Routing Protocols and Computation in Silicon

I got this question and I guess it may not be obvious to everyone so I’ll have a shot at answering it.

Technology advances in ASIC hardware have resulted in substantial improvements in switching performances of routers and switches. However, the routing processes are still dependent on CPU speeds. What are the existing limitations in router/switch models which prevent route computations from being performed in hardware?
