METHOD, DEVICE AND SYSTEM FOR PUBLISHING INTER-DOMAIN LINK INFORMATION

摘要

The present invention provides a method, device and system for publishing inter-domain link information. The method comprises: a first path calculating unit obtaining inter-domain link information between each administered autonomous system domain and a neighbor autonomous system domain; the first path calculating unit publishing the inter-domain link information to a second path calculating unit through a self-contained inter-domain route example, both the first path calculating unit and the second path calculating unit comprising the inter-domain route examples, and the inter-domain route example contained in the first path calculating unit and the inter-domain route example contained in the second path calculating unit belonging to the same inner gateway protocol domain. Embodiments of the invention can implement publishing of the inter-domain link information among different path calculating units.
