Abstract:
1. A method for dynamically allocating link bandwidth on a Resilient Packet Ring having a plurality of nodes, which is based on fairness bandwidth calculation per advertisement interval, comprising the following steps in one advertisement interval: measuring an add rate which is a byte count for local packets added onto the ring by at least one of the nodes for fairness eligible packets, a total_add_rate which is a total byte count for local packets added onto the ring by at least one of the nodes, an fw_rate which is a byte count for transit packets on the ring for the fairness eligible packets, and a total_fw_rate which is a total byte count for transit packets on the ring; the counts being related to data packets on each node of the Resilient Packet Ring; calculating a local fair rate of each node on the Resilient Packet Ring using the measured counts; determining an advertising rate of each node on the Resilient Packet Ring based on the local fair rate and an advertising rate provided by a downstream node; and each node on the Resilient Packet Ring transmitting data packets with the determined advertising rate; wherein the step of calculating a local fair rate of each node on the Resilient Packet Ring using the measured counts comprises:
