ABSTRACT:
An improved group-based routing update technique allows limited per neighbor customization of routing update messages generated by an interdomain router for its neighboring peer routers within autonomous systems of a computer network. The technique may be employed when the neighboring peer routers share identical routing policies, but the routing update messages differ only in certain attributes with known locations and lengths. Appropriate values of the location and length attributes for each neighboring router are calculated and stored during a replication stage of the improved technique. Before each message is transmitted, the proper location and length attributes of the message are updated with the stored values for the respective neighbor.
