METHOD, DEVICE AND SYSTEM FOR ADVERTISING INTER-DOMAIN LINK INFORMATION AND COMPUTING INTER-DOMAIN ROUTE

摘要

The present invention discloses a method for advertising the inter-domain link information. The two ends of the inter-domain link are respectively the first end node and the second end node, and the first end node and the second end node belong to a same autonomous system. The method includes: the first end node generates the first inter-domain link information; the first inter-domain link information includes the address information of the first end node, the address information of the second end node, the domain address information of the domain in which the first end node locates, and the domain address information of the domain in which the second node locates; the first end node sends the first inter-domain link information. The present invention discloses a device for advertising inter-domain link information as well, and a method, device and system for computing inter-domain link route. By applying the technical solution of the embodiments of the present invention, the advertisement of inter-domain link information is implemented, the static routing allocation is not necessary, the partition of initial domain is not changed, and the problem that the static routing allocation results in making mistake easily and slow allocation rate can be avoided.
