Abstract
Each domain of a multi-domain network collects intra-domain routing information relating to that domain and makes a reduced view of that information available to other domains of the network, and in which each domain of the network uses its own intra-domain routing information together with the reduced-view routing information from the other domains to form a logical view of the network so as to enable that domain to make an end-to-end route selection decision.
Claims36
A method for use in a multi-domain network environment, comprising:
- each domain of the multi-domain network collecting intra-domain routing information relating to that domain;
- providing a reduced view of that information to other domains of the network, and
- each domain of the network using its own intra-domain routing information together with the reduced-view routing information from the other domains to form a logical view of the network so as to enable that domain to make an end-to-end route selection decision.
A multi-domain network in which each domain of the network is arranged to
- collect intra-domain routing information relating to that domain and to make a reduced view of that information available to other domains of the network, and
- use its own intra-domain routing information together with the reduced-view routing information from the other domains to form a logical view of the network so as to enable that domain to make an end-to-end route selection decision.
Apparatus for use in a domain of a multi-domain network, the apparatus being provided by one or more nodes of that domain and comprising
- collection means for collecting intra-domain routing information relating to that domain,
- view reduction means for making a reduced view of that information available to other domains of the network, and
- aggregation means for forming a logical view of the network using the collected intra-domain routing information together with reduced-view routing information from the other domains so as to enable an end-to-end route selection decision to be made based on the logical view.
