Embodiment Construction

[0027] Combine the following Figure 1 to Figure 4 An embodiment of the present invention will be described.

[0028] figure 1 It is a flowchart of a user access method in an embodiment of the present invention. The method includes:

[0029] 102. Generate a routing table according to the user routing information released by the accessed AR.

[0030] 104. Receive the message, and obtain multiple equal-cost routes to the destination user of the message according to the destination user information of the message and the routing table. The multiple equal-cost routes are multiple equal-cost routes whose next hops are different AR users. The different AR users may be AR users of different ARs, or AR users of the same AR who access with different access user identities. The destination user information includes destination IP and virtual private network (Virtual Private Network, VPN) information. Check the routing table according to the destination IP and VPN information to ob...

Abstract

The invention relates to the network communication field, in particular to a user access method, a device and a system. The method comprises the following steps: generating a route table according to user route information released by an connected access router (AR); receiving a message, and acquiring a plurality of equivalent routes reaching the destination user of the message according to destination user information of the message and the route table; selecting one available route from the equivalent routes according to a route selection algorithm; and forwarding the message from the available route according to the AR access manner. By adopting the technical scheme, the access route is selected from the equivalent routes according to the route selection algorithm, so that loads can beshared by the equivalent routes and other available routes can be selected when the route is failed, thereby solving the problem in fully utilizing the user access link on the premise of ensuring theuser access reliability.

Description

technical field [0001] The present invention relates to the field of network communication, in particular to a user access method, device and system. Background technique [0002] Currently, more and more users connect to the Internet (Internet) through an access router (Access Router, AR). The AR accesses the Broadband Access Server (Broadband Access Server) of the Internet Service Provider (Internet Service Provider, ISP) through Point-to-Point Protocol (Point to Point Protocol, PPP) dial-up or Layer 2 Tunneling Protocol (Layer 2 Tunneling Protocol, L2TP) tunnel mode. , BAS) equipment. [0003] The following solution implements user access: the AR connects to the BAS through PPP dial-up or L2TP tunneling, and the user connects to the BAS device through the AR. Through dynamic learning or static configuration, the AR advertises the Internet Protocol (Internet Protocol, IP) address of the user it accesses to the BAS device. When packets from Internet or public network use...
