Abstract
A system and method for data communication in a multi-controller environment is disclosed. The system and method utilize a sequence number protocol to filter duplicate packets, adapt to transient errors, and to reroute data packets to avoid hardware malfunctions. The system and method further employ a transaction database to track packet communication in accordance with the sequence numbers. Moreover, the system and method may be implemented in hardware or software to provide a transparent transport layer to higher level hardware layers. The system and method utilize sequence number domains and a bridging protocol to reduce requirements associated with maintaining sequence number threads.
