摘要

A technique for performing adaptive rate limiting of flow probes is described. The technique includes sending a plurality of flow probes from a first service engine to at least one other service engine. The flow probes are sent at a rate that does not exceed a rate limit. A flow probe of the plurality of flow probes is generated in response to the first service engine receiving a mid-flow packet for a flow that is not recognized by the first service engine. A recipient service engine of the flow probe responds with a success indicator if the recipient service engine recognizes the flow. The technique also includes determining a success rate associated with success indicators received from the at least one other service engine and comparing the success rate with a first threshold. The rate limit is adjusted in response to a comparison result.

Here, <to SE 410> represents the binding for the flow. Flow A and Flow B are now recognized by service engines 420 and 430, respectively. Consequently, asterisks for these flows are no longer present.

Now suppose mid-flow packets for a new flow, Flow H, are present in system 400. Flow H is not based on an existing connection and is not due to rerouting of an existing flow. Thus, packets from Flow H may be part of an attack. Router 402 directs packets from Flow H to service engine 410. The resulting flows are:
