摘要：A method and apparatus for communicating congestion control information between dissimilar protocols operating in heterogeneous internetworks at different layers of the International Standards Organization (ISO) Open Systems Interconnection (OSI) 7 layer conceptual model for data networking. The method and apparatus provides direct end-to-end congestion control at the Transport layer across a TCP/IP and ATM internetwork utilizing ATM ABR and TCP sliding window flow control mechanisms. A network device that interconnects TCP/IP and ATM data networks for communication of data communicates network congestion detected by a protocol operating in the ATM data network to a heterogeneous protocol operating in the TCP/IP data network. The network device receives TCP data packets and stores them in a queue. A TCP packet is discarded if the queue is full or network congestion is detected by the protocol operating in the ATM network, to communicate network congestion in the ATM network to the heterogeneous protocol operating in the TCP/IP network.
