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 solves the shortcomings of weak AAA function and decentralized user management in PPPoE and DHCP, it still has the defect of not being able to intelligently configure CMs to different LANs, and the implementation is not flexible enough.

Embodiment Construction

[0044] The solution of the present invention is mainly based on configuring different VLAN domains of the CM, 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 user messages can be uniformly authenticated through the B-RAS, that is, a relatively complete user management can be realized through the B-RAS.

[0045] Specifically, the solution of the present invention first needs to set each VLAN domain and corresponding ID, and then allocate the CM in the network to each VLAN domain. Wherein, allocating the CM in the network to each VLAN domain can be achieved by saving the correspondence 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; it can also sav...

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 field of network transmission technology, and more specifically to a method for realizing message forwarding. Background technique [0002] At present, the coaxial optical fiber hybrid network (HFC) network access technology is currently a more popular access method, which is mainly through the operation of the cable-based data service interface specification (DOCSIS) / European DOCSIS standard (EuroDOCSIS) on the HFC network. ) Protocol to provide users with broadband access services. [0003] When realizing access through the HFC network, a cable modem terminal system (CMTS) located between the HFC network and the IP network is required to provide an access method. There are three main ways of CMTS access: Ethernet-based Point-to-Point Protocol (PPPoE), Dynamic Host Configuration Protocol (DHCP), and Layer 2 transparent transmission. [0004] Among them, both the PPPoE and DHCP methods will terminate the access on the CM...
