Description

A remote management method and system for bridge equipment

technical field

The present invention relates to the communication field, in particular to a remote management method and system for bridging equipment.

Background technique

At present, the industry widely uses XDSL (a general term for various digital subscriber lines (Digital Subscriber Line, DSL), including HDSL, SDSL, VDSL, ADSL and RADSL, etc.) technology to provide users with broadband access. For example, China Telecom already has thousands of million XDSL access users. Every user has an XDSL modem in his hand, how to effectively manage such a huge number of XDSL modems has always been a concern of telecom operators.

In the past XDSL modems, in order to reduce costs, stabilize performance, and limit the number of devices that users can access through XDSL modems to a certain extent, most XDSL modems are factory-configured as bridging mode, or some modems are only for The user provides a bridging access method. These XDSL modems with bridging function only play the role of bridging, and the device itself does not have a public network IP address. This makes the maintenance and asset management of XDSL modem devices quite difficult under the currently widely used IP network. difficulty.

For the remote management scheme of XDSL modem, the industry has also proposed some methods, such as the remote management method based on the permanent virtual circuit (Permanence Virtual Circuit, PVC), the remote management method based on the embedded operation channel (Embedded Operational Channel, EOC), etc.

Based on the PVC remote management method, a PVC channel specially used to transmit management information is established between the Digital Subscriber Line Access Multiplexer (Digital Subscriber Liner Access Multiplexer, DSLAM) and the XDSL modem, and the management function of the modem is realized by using the PVC channel ( Telnet, HTTP, etc.). This remote management method needs to rectify the existing network and add a PVC dedicated to management. At the same time, the modem itself will occupy an IP address in order to realize the management function. For today's increasingly tense IP addresses, this seems a bit wasteful.

In the remote management mode based on the EOC channel, the EOC channel complies with the relevant requirements on EOC in ITU-TG.997.1, and is a channel specially used to carry user terminal management information. This method requires ADSL central office equipment and ADSL user terminal equipment to support High Level Data Link Control (HDLC) to encapsulate management data packets and clear EOC messages.

Since the EOC channel only supports 4kbps traffic, the bandwidth is small; at the same time, it is necessary to perform special processing on the bearer messages on the EOC management channel, such as: the simple network management protocol (Simple Network Management Protocol, SNMP) of the bearer needs to identify the SNMP message and protocol It is directly mapped to the HDLC frame, and then carried to the EOC channel.
