PEAK LOAD-BASED CONGESTION CONTROL METHOD IN OPTICAL BURST SWITCHING NETWORKS

摘要

A method for controlling congestion based on peak load values in optical burst switching networks is provided to maintain reasonable level in the aspect of flow rate fairness and signaling overhead. A method for controlling congestion based on peak load values in optical burst switching networks comprises the following steps of: periodically transmitting load messages from an output node to an input node(s100); processing the load messages received from an intermediate node and transmitting an NAK(Negative Acknowledge Character) message to the input node(s200); increasing/decreasing a burst transmission rate by comparing NAK messages or peak-load value with the load message(s300); and initializing the NAK messages to zero by a congestion controlling unit(s400).
