A METHOD, SYSTEM AND NETWORK DEVICE FOR PERFORMING PATH COMPUTATION BETWEEN AUTONOMOUS SYSTEMS

摘要

A method, system and network device for performing path computation between autonomous systems is provided. Wherein, the method comprises: obtaining the inter-domain connection information of each ASBR itself advertised by every autonomous system border router ASBR within the local autonomous system; establishing the autonomous system border connection information based on the obtained inter-domain connection information and performing the path computation based on the autonomous system border connection information. By the ASBR advertising the inter-domain connection information within the local autonomous system and establishing the autonomous system border connection information based on the inter-domain connection information, the question about the autonomous system border connection information can not be obtained is solved and the path computation between autonomous systems is achieved.
