Intel: Arista uses our Merchant Silicon

Intel is crowing about their silicon being used in Arista’s 7124SX switch. Note that this is Intel’s switching silicon (from their purchase of Fulcrum not the FPGA.). At Network Field Day, Arista was at pains to avoid discussing their merchant silicon vendors, claiming that they choose the best chipset available at any time.

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?
