Method, device and system for communication agent

Abstract

A method, device and system for communication proxy are provided. After receiving an interactive message between a provider device and an access device, performing a converting process between a physical port and a logical port on the physical port information or logical port information in the received message, according to the obtained predetermined mapping information between the physical port and the logical port, thereby the physical port between the provider device and the access device is isolated.

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 lines from multiple network operators, and each network operator has its own identification method for physical lines, it is difficult for ISP to manage lines leased from different network operators in a unified way;

[0013] (4) It is difficult to find the physical port

[0014] Because there is no fixed rule for the arrangement of physical ports, it is difficult to organize physical port identification into a continuous arrangement, making it difficult to search for physical ports; if an advanced search algorithm is used, a large amount of storage space must be consumed, and the real effective data only takes up Sporadic small part of the storage space; at the same time, in order to improve storage efficiency, only valid data must be stored. At this time, the physical port search must be compared one by one, resulting in a decrease in search efficiency
