Problems solved by technology

Therefore, the disadvantage of this access method is: the AAA function of the system is not powerful enough, and the management is scattered, so it is impossible to perform unified access user management on the B-RAS
Although this method

Embodiment Construction

[0045] The scheme of the present invention is mainly based on CM configuring different VLAN domains, and setting the ID of the corresponding VLAN domain to which the CM belongs in the message, so that the CMTS can have a more powerful access function. In this way, after the CMTS sends various user messages to the B-RAS, the B-RAS can perform unified authentication on the user messages, that is, the B-RAS can realize relatively complete user management.

[0046] Specifically, the solution of the present invention first needs to set each VLAN domain and the corresponding ID, and then assign the CMs in the network to each VLAN domain. Wherein, assigning the CMs in the network to each VLAN domain may be realized by storing the corresponding relationship between the identification information of the CM and the VLAN ID. And saving the corresponding relationship can specifically save the corresponding relationship between the MAC address of the CM and the VLAN ID; the corresponding r...

Abstract

The method sets up each VLAN field and relevant ID in advance, assigns CM in network to each VLAN field, and configures up going output interface at network side of each VLAN field. The method further includes (1) after receiving message from user side, CMTS determines whether CM of sending the message belong s to VLAN field set in advance; if no, carrying out forwarding according to normal forwarding flow, and ending the process flow; otherwise, executing step (2); (2) CMTS determines output interface in use for forwarding the message, and adds ID of VLAN field, which the CM of sending the message belongs to, to head of the message; through the output interface, the method forwards the message. The invention also disclosed another method for forwarding message. Forwarding up going and down going messages, the invention also realizes distribution of different VLAN field based on CM, i.e. distributing VLAN ID corresponding to CM intelligently.

Description

technical field [0001] The present invention relates to the technical field of network transmission, and more precisely relates to a method for realizing message forwarding. Background technique [0002] At present, the hybrid coaxial fiber optic (HFC) network access technology is currently a popular access method, which is mainly through the operation of the cable-based data service interface specification (DOCSIS) / European DOCSIS standard (EuroDOCSIS standard) on the HFC network. ) agreement to provide users with broadband access services. [0003] When the access is implemented through the HFC network, a cable modem termination system (CMTS) located between the HFC network and the IP network is specifically required to provide an access mode. There are mainly three access modes of CMTS: Ethernet-based point-to-point protocol (PPPoE) mode, dynamic host configuration protocol (DHCP) mode and Layer 2 transparent transmission mode. [0004] Among them, both the PPPoE mode a...
