Method and Network Element for Rerouting Traffic, While Maintaining the Quality of Service, in Networks with Slow Route Convergence

摘要

A route for routing traffic is established by the emission of a route announcing message to a network element of a network. The network element is then triggered in such a way as to route the traffic according to the route announced in a time-delayed manner by means of an event e.g. the emission of another message. A resource reservation for routing traffic along the announced route is carried out between the route announced and the event. In this way, it is ensured that the required resources are provided for the deviation of traffic onto the new route, and a route modification for traffic can be carried out without affecting the quality of service.
