Abstract:
1. A computing system for processing network traffic, comprising: a plurality of network ports of a network device configured to receive network traffic; a plurality of processing blades of the network device, not directly coupled with the plurality of network ports, configured to process the network traffic, each of the plurality of processing blades belonging to one or more session pairs of processing blades; a switch of the network device coupled with the plurality of processing blades and configured to support inter-blade communications among the plurality of processing blades; a router of the network device disposed between, and coupled with, the switch and the plurality of network ports, the router configured to forward the network traffic from the switch to one or more of the plurality of processing blades based on forwarding rules without communicating with other switches; and a system controller of the network device disposed between, and coupled to, the router and the plurality of processing blades, the system controller configured to detect a fault of one of the plurality of processing blades and further configured to update the forwarding rules of the router, upon detecting the fault, to divert the network traffic from the faulted processing blade to at least one different processing blade.
