Abstract

In the invention, the master control board comprises: a control unit of master control board, which is used for sending the management message to PCIe switching unit and receiving the feedback information from the controlled board; a PCIe switching unit used for relaying the management message to the controlled board and relaying the feedback message of the controlled board to the control unit of master control board. Said controlled board comprises: PCIe isolation unit used for receiving the management message from the master control board, relaying it to the controlled board and sending the feedback message to the master control board; and a control unit of the controlled board, which is used for receiving the management message, and sending the feedback message to the PCIe isolation unit. By the invention, the management message can be transmitted through DMA in CPU.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and a system for implementing internal management channels of network equipment. Background technique [0002] At present, most high-end network devices are composed of main control boards, switching fabric boards, line card boards, backplanes and power supplies. High-end network devices include: high-end routers and Ethernet switches. The main control board is responsible for initialization, dynamic configuration, and routing management of the switching network board and line card board; the switching network board is responsible for forwarding the service data flow of each line card board; Processing, and then forwarded to the switching network board, such as ATM (Asynchronous Transfer Mode, asynchronous transfer mode), POS (Packet Over SONET / SDH, based on SONET (Synchronous Optical Networking, synchronous optical network) / SDH (SynchronosDigitalHierarchy, synchro...
