Abstract
A network processing system is described that is able to bind all the network traffic related to a bi-directional communication. Unidirectional processing engines take the data from line interfaces, and associate each data packet with an identifier, which identifies the flow of which the data packet is a part. The flows examined to determine if they are part of a bi-directional communication. If the flow is part of a bi-directional communication information related to the return flow or flows is extracted and passed to the unidirectional processing engine handling the flows in the opposite direction. This processing engine then pre-allocates resources in anticipation of the return flows. The pre-allocation of resources includes creating an entry in a session memory that contains state information on the flows passing through the network processing system.
