Abstract

The invention discloses a network access method, device and system. The network access method comprises the following steps: sending an on-line authentication request of a user to an access server; receiving a response which is sent by the access server through a first interface, and then forwarding the response to the user; and forwarding a network access request of the user from a first Trunk member interface to the access server, wherein, the access server receives the on-line authentication request through the first interface, the response comprises an MAC (Media Access Control) address of a gateway, and the MAC address of the gateway is the MAC address of the first Trunk member interface corresponding to the first interface. By implementing the technical scheme of the invention, the on-line authentication path and network access path of the user are ensured to be consistent, convenience is provided for traffic policing on the access server, meanwhile user resource synchronization can be avoided among a plurality of Trunk member plates, and the problem of performance reduction of an SR (Service Router) / BRAS (Broadband Remote Access Server) is solved.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a method, device and system for accessing a network. Background technique [0002] In terms of the layered structure of the network and the reasonable allocation of broadband, Trunk is interpreted as "port aggregation", which is an important way of bandwidth expansion and link backup. Trunk bundles multiple physical ports together as a logical port, and can superimpose the bandwidth of multiple groups of ports. Trunk technology can realize the mutual backup function of multiple links inside the trunk, that is, when a link fails, it will not affect the work of other links, and traffic balance between multiple links can be achieved. [0003] figure 1 It shows the application scenario of using Trunk as user access. User A's online or authentication packets are HASHed on the switch to the forwarding path of the dotted line; user's service packets are forward...
