Abstract:
1. A method to exchange routes in a communication network, the method comprising: receiving, using a processor, first routing information describing a first route, the first routing information comprising a route identifier identifying the first route and a first plurality of route parameter values characterizing the first route; associating the first plurality of route parameter values of the first route with a first route parameter set that is to include the first plurality of route parameter values; and in response to determining that the same first route parameter set was already sent to a recipient in the communication network when a description of a second route different from the first route was previously forwarded to the recipient, forwarding a description of the first route to the recipient by sending, using the processor, a border gateway protocol update message to the recipient, the border gateway protocol update message being modified to include both the route identifier and a pointer, and to not include the first route parameter set which has the first plurality of route parameter values, wherein the pointer corresponds to the first route parameter set and is determined by processing at least one of the first plurality of route parameter values with a hash function.
