Communication proxy method, apparatus and system

Abstract

Disclosed is a method, a device and a system of communication proxy for processing the conversion of the physical port and the logical port towards the received physical port information or the logical port information according to the acquired preset mapping information between the physical port and the logical port after the message interacted between the operator device and the access device is received so that the physical port between the operator device and the access device is separated; thereby, not only the changing of the physical port is ensured to have no influence on the process of operation development of the operator device, but also the safety of each physical port of the access device is ensured.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an implementation scheme for communication between multi-operator equipment and access equipment Background technique [0002] In the access network, in order to effectively support new services, it is necessary to add corresponding control functions to the equipment of the access network, so that the operation support equipment can control the corresponding equipment of the access network and realize the control of new services. support. [0003] The access network may often contain a large number of devices that need to be controlled by the operation support device, such as a large number of ANs (access nodes). Therefore, in order to reduce the control burden of the operation support device L2CP (Layer 2 Control Protocol) is adopted in the network, and devices such as AN in the access network are controlled through BRAS (Broadband Access Server). [0004] Take ...

Problems solved by technology

[0007] (1) Poor scalability

[0008] When the DSLAM is upgraded or other maintenance is performed, it is necessary to ensure that the physical ports do not change, otherwise, the ISP will not be able to control the corresponding physical ports. To ensure that the physical ports are controlled, the ISP must be reconfigured, thus increasing the Difficulty in expanding DSLAM; at the same time, coordinating between network operators and ISPs brings considerable operational impact and costs;

[0009] (2) There are potential safety hazards

[0010] The ISP directly controls the DSL physical port of the network operator's DSLAM equipment through L2CP, and the network operator will have to directly disclose its network deployment to competitors, and there are hidden dangers in security;

[0011] (3) Physical port maintenance is inconvenient

[0012] ISP may lease lin
