AI Technical Summary

Problems solved by technology

It has the same disadvantages as pure broadband equipment: complex management, each box needs a management IP address
[0016] To sum up, in the existing technical solutions, the management of the cascaded network based on the Ethernet bus is complex, and the maintenance and management costs are relatively high.

Embodiment Construction

[0034] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] FIG. 1 shows the structure of an Ethernet bus-based access device provided by Embodiment 1 of the present invention.

[0036] The main frame service board 11 is directly connected to the main frame main control board 12 through the backplane Ethernet bus (not shown), wherein the main frame main control board 12 is integrated with a local area network switching chip (such as an Ethernet switch LanSwitch, LSW) , the LAN switching chip provides an Ethernet interface to the outside. When the service board 11 of the main frame is connected to the main control board 12 of the main frame, the physical interface may be FE / GE or other Ethernet interfaces.

[0037] The interface unit 13 is arranged on the main frame main control board 12 in an integrated manner, and is connected with the main frame main control board 12 through the backplane Ethernet bus ...

Abstract

A master-slave frame communicating method of access device based on Ethernet bus includes configuring media access control MAC address of slave frame master control board by master frame master control board, configuring MAC address of its own service board separately by master frame master control board and slave frame master control board, carrying out communication between various master boards of master / slave frame as well as between master frame master control board and various service boards by utilizing configured MAC address. The access device based on Ethernet bus is also disclosed.

Description

technical field [0001] The invention relates to the communication field, in particular to an access device based on an Ethernet bus and a master-slave frame communication method thereof. Background technique [0002] Generally, it is logically considered simply that an integrated access device (Multi-Service Access Node, MSAN) is composed of a narrowband service frame and a broadband service frame. [0003] At present, in the pure narrowband field, there is an implementation scheme for the slave frame, which is basically based on the Time Division Multiplex (TDM) networking. The master frame and the slave frame are connected physically through E1, and logically through the internal private protocol. interconnection. [0004] However, in the field of broadband digital subscriber line access multiplexer (Digital Subscriber Line Access Multiplexer, DSLAM), it is basically a single-frame solution and does not support slave frames. In this way, with the expansion of users, ther...
