New contention control mechanisms for FDDI

Contention control strategies for high speed backbone networks are studied. Packet loss is a serious problem in a backbone scenario due to the speed mismatch of the different networks. The authors' new mechanism tries to reduce the packet loss ratio for fiber distributed data interface (FDDI) operating as a backbone. When one buffer is overloaded and packets would be lost, the new schemes try to store those packets at another station. The proposed mechanism provides significant reduction in packet loss and prevents congestion in other parts of an interconnected network.
