Embodiment Construction

[0015] According to the present invention, the method for realizing the link aggregation function based on policy routing is specifically as follows:

[0016] In the broadband access server, an uplink port connected to the backbone network is regarded as a gateway. When the system is configured with multiple uplink ports, there are multiple gateway outlets.

[0017] First, configure the mapping relationship between the gateway link of the broadband access server and the user access service through the management and maintenance console, and specify the primary and backup service egresses of the user service. In the broadband access server, users are divided into user groups according to the assigned subnets. One user group corresponds to a layer-3 IP port of the broadband access server, and a gateway corresponds to an uplink layer-3 IP port. The mapping relationship here refers to assigning all session transmissions of a user group to the same gateway link outlet to send and r...

Abstract

This invention discloses a method for implementing link aggregation based on policy-based routing. It includes following steps: the user sends the PPP calling to the wideband access server, the above sever completes the service access, transmits process and service reversing of PPF / IP, when the state of gate exit link turns on, sends the user data to the router, the down stream data is sent to the wideband access server through the router. When the gateway exit link turns off , the user data is sent to backup router, the down stream user data is sent the wide band server through the backup router. The invention can implement the configuration management for the exit of main rout reliably and high efficiently.

Description

technical field [0001] The invention relates to a method for realizing a link aggregation function in the communication field, in particular to a method for providing multiple network egress service management in a broadband access server. Background technique [0002] According to the provisions of "Network Access Server - Broadband Network Access Server" formulated by the Ministry of Information Industry of the People's Republic of China, the general broadband network structure is divided according to the access layer, aggregation layer and backbone layer. Broadband access servers are placed on the aggregation layer and the backbone layer to complete various access services for users. The broadband access server at the aggregation layer is the core node for the aggregation of various broadband access users, and is the link between the access layer and the backbone layer. Generally, the broadband access server, as the PE function node of the net...
