System and Method for Integrating Line-Rate Application Recognition in a Switch ASIC |
摘要 |
A system and method for integrating line-rate application recognition in a switch ASIC. Switching platforms can be built using this feature with a conventional control plane processor rather than a more expensive specialized processor. A deep packet inspection system can be embodied in a switch ASIC using a flow tracker and a signature matching engine. The flow tracker can be positioned in an ingress portion of the switch ASIC at a location where packets in a bi-direction flow can be observed and recorded. The flow tracker generates a signature match request that is forwarded to a signature matching engine in an auxiliary pipeline. The signature matching engine analyzes packets using signature matching state machine and reports the signature matching results to the flow tracker using a response packet that is sent to the ingress pipeline.
