Ethernet bridge equipment, MAC address learning method and data packet transmission method

Abstract

The invention provides an Ethernet bridge device, an MAC address learning method and a data message transmission method. The Ethernet bridge device comprises an MAC address learning prohibition information storage module and an MAC address learning module, wherein the MAC address learning prohibition information storage module is used for storing information on whether or not to prohibit MAC address learning based on VLAN, and the MAC address learning module determine whether to prohibit the MAC address learning or not according to the information stored in the MAC address leaning prohibitioninformation storage module. The MAC address learning method reduces the requirements of an access convergence network on the MAC address table storage space of the Ethernet bridge device, allows the access convergence network to be accessed by more users and contributes to the expansion of networks. At the same time, the data message transmission method avoids accessing an MAC address table during transmission and contributes to the reduction of equipment cost. Therefore, the establishment cost of the access convergent network is reduced.

Description

technical field [0001] The invention relates to the technical field of telecommunication, in particular to an Ethernet bridge device and its MAC address learning method and data message transmission method. Background technique [0002] The network model of the broadband access network is attached figure 1 shown. [0003] exist figure 1 Among them, the broadband access network system mainly includes: user access equipment, network aggregation equipment, BRAS (broadband access server), AAA (authentication and accounting server), etc. Among them, the user access equipment is 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 device is used to implement the user line tandem function. The network aggregation device connects the user access device to the broadband access server. The broadband access server term...

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
