ROUTE SELECTION WITH BANDWIDTH SHARING OPTIMIZATION OVER RINGS

摘要

A method for establishing a connection through a communication network (20) that includes multiple segments (25) includes providing a sharing definition defining a sharing of bandwidth among connections in the network. Two or more candidate routes (40, 44, 52, 56) for a new connection to be established through the network are identified. For each of the two or more candidate routes, a cumulative additional bandwidth reservation to be allocated to the new connection in the segments along the candidate route is calculated responsively to the sharing definition. A preferred route having a minimum value of the cumulative additional bandwidth reservation is selected out of the two or more candidate routes. The new connection is established using the preferred route.
