Abstract
A transport control server, a network system, and an aggregated path setting method for avoiding congestion on the bypass destination route when an aggregated path consisting of a group of paths was bypassed (diverted) to a bypass destination route. Edge nodes measure the traffic information flowing along each path and notify the transport control server. The transport control server calculates the available capacity of bypass destination routes for each aggregated path based on this traffic information. After receiving a path add request, the transport control server assigns additional paths to the aggregated path so that the aggregated path traffic band that was assigned additional paths, does not exceed the available capacity on the bypass path. The transport control server sends an aggregated path set message to the edge nodes. The edge node complies with the aggregated path set message received from the transport control server and sets the aggregated path.
