Abstract:
A method for reserving spare bandwidth for a link in a communication network including a plurality of links comprising the steps of:monitoring the volume of traffic routed through each link of the communication network; simulating a single link failure for each link of the communication network; determining the volume of traffic which would be rerouted through each link for maintaining existing communication after each of the simulated single link failures; determining the volume of traffic removed from each link, if any, after each of the simulated single link failures; calculating for each link the difference between the volume of traffic which would need to be rerouted through each link and the corresponding volume of traffic removed from each link for each of the simulated single link failures; determining for each link the maximum value of the calculated differences for all simulated single link failures; and reserving for each link an amount of spare bandwidth equivalent to the determined maximum difference.
