A method and an apparatus for advertising border connection information of autonomous system are disclosed. Moreover, the method includes: establishing and maintaining, by a border node of the autonomous system, the border connection information of the autonomous system; flooding the border connection information within the autonomous system; and receiving, by nodes of the autonomous system, the border connection information. The method and the apparatus for advertising border connection information of autonomous system of embodiments of the present invention may adapt to dynamic change of network topology, and dynamically advertise the border connection information of the autonomous system within the system in time, so as to optimize networks and improve quality of service of the networks.

A method for route updating includes: a. determining more than one route in accordance with a predetermined preset mechanism and sending the determined more than one route to a client and/or a non-client, by a reflector in a route advertisement, and saving more than one route reaching the same destination address by the client and/or the non-client; and b. sending to the client and/or the non-client a message carrying information on the next hop of the route to be withdrawn, by the reflector in a withdrawal of a route and withdrawing the corresponding route for route updating in accordance with the information on the next hop carried in the message, by the client/the non-client. A system for route updating and a router reflector is also provided.

A method for implementing path computation in a domain includes: storing, in each of path computation elements of a domain, global path computation information for path computation in the domain; and performing path computation by the path computation element in accordance with the global path computation information if a path is to be established as requested. A device for implementing path computation in a domain includes: a storage unit for storing global path computation information used for path computation in a domain; and a computation unit for performing path computation in accordance with the global path computation information stored in the storage unit if a path is to be established as requested.

Method and apparatus for computing a path in a network domain

A method for processing distributed path computation requests includes: storing all path computation requests in an autonomous system, in each of Path Computation Elements (PCEs); and performing a path computation by a PCE in accordance with a path computation request obtained from the all path computation requests.
