ABSTRACT:
Synchronization of network traffic compression mechanisms deployed in redundant network topologies. In one implementation, the present invention features the synchronization of compression statistics on redundant network devices to facilitate failover and load sharing operations in the management of data flows traversing computer network environments. In one implementation, compression meta data is appended to synchronization packets and transmitted to one or more partner or redundant network devices. The receiving network devices use the compression meta data to synchronize one or more data flow control processes or data structures. Implementations of the present invention also feature process flows that increase the efficiency of synchronizing compression related operations.
