Communication equipment and method for achieving out-of-band monitoring and management, and master-slave switching method

Abstract

The invention discloses communication equipment for achieving out-of-band monitoring and management, which comprises a micro processing unit and a managed board card consisting of at least one switch fuse unit and at least one line processing unit, wherein the micro processing unit comprises an FPGA (Field Programmable Gate Array); each managed board card comprises a singlechip; the FPGA of the micro processing unit is connected with a CPU (Central Processing Unit) of the micro processing unit by an expanded local bus, connected with the singlechip of each managed board card by simulating UART (Universal Asynchronous Receiver / Transmitter) buses with the corresponding quantity, and used for receiving a management command from the CPU of the micro processing unit through the local bus, forwarding the management command to the singlechips of the corresponding managed board cards through the UART buses, receiving management response commands from the singlechips of the managed board cards through the UART buses, and sending the management response commands to the CPU of the micro processing unit; and the singlechips of the managed board cards are used for receiving the management commands from the FPGA of the micro processing unit through UART interfaces, and sending the management response commands to the FPGA of the micro processing unit through the UART interfaces. The invention further discloses a method for achieving the out-of-band monitoring and management and a master-slave switching method. The communication equipment, the method and the master-slave switching method can effectively improve the data forwarding efficiency.

Description

technical field [0001] The invention relates to the technical field of monitoring and management of communication equipment, in particular to communication equipment, a method and a master-slave switching method for realizing out-of-band monitoring and management. Background technique [0002] With the increasing popularity of the network, the amount of network data is increasing, and the network communication equipment is becoming more and more complex. At present, the communication equipment in the provincial, municipal and even national data centers basically adopts rack-mounted communication equipment to improve Data forwarding capability and system reliability. Rack-mounted communication devices, such as routers and switches, generally have a main control card (MPU), a switch card (SFU) and multiple line cards (LPU) working together. The line card is responsible for the data forwarding of the interface within the line card, the switch card is responsible for the data f...

Problems solved by technology

[0003] Existing methods for transferring management data are: Image 6 As shown, the central processing unit CPU of the main control card, line card, and switch card is led to the same bus, and hung on a bus through the backplane, which is specially used to transmit management data, because the connection signals between boards are scarce resources. Therefore, such a bus generally uses a bus with a small number of lines, such as a two-wire serial bus I2C. However, this transmission method is not conducive to the parallel processing and real-time interaction of data between the main control card and each managed board.
