Ethernet bridge apparatus and MAC address learning method and data message transmission method

Abstract

The invention relates to Ethernet bridge device, MAC address learning method and data report transmission method, wherein said Ethernet bridge device comprises: a forbid MAC address learning information storage module and a MAC address learning module, while the first stores the information that forbids or allows MAC address learning based on VLAN and the second module confirms if forbids the MAC address learning based on the stored information. The invention can reduce the demand of access network for the storage space of MAC address list, to access more users to the access network; at the same time, the invention can avoid accessing MAC address list when transferring data, to reduce the cost.

Description

Technical field [0001] The invention relates to the technical field of telecommunications, in particular to an Ethernet bridge device, a MAC address learning method and a data message transmission method. Background technique [0002] The network model of broadband access network is attached figure 1 Shown. [0003] in figure 1 Among them, the broadband access network system mainly includes: user access equipment, network convergence equipment, BRAS (Broadband Access Server), AAA (Authentication and Accounting Server), etc. Among them, user access equipment such as DSLAM (digital subscriber line access multiplexer), LAN Switch (local area network switch) and so on. Network aggregation equipment such as ATM switches, Ethernet bridge equipment, etc. [0004] The user access equipment is used to implement the user line tandem function. The network aggregation equipment connects the user access equipment to the broadband access server, and the broadband access server terminates the...

Problems solved by technology

[0012] When building an access convergence ring network, if a high-end Ethernet bridge device with the advantages of large MAC address table space is used, the networking cost will be too high; if a medium-low In the networking of end Ethernet bridge devices, there may be a phenomenon that the MAC addresses of some users cannot be learned. In this way, the packets sent to these users can only be broadcast, which wastes network bandwidth and increases network instability. , and, when a large number of users need to be connected, multiple rings need to be formed, which ultimately increases the networking cost
