Problems solved by technology

[0014] 1. All data sending and receiving needs to be packaged and unpacked, and corresponding commands need to be sent for handshake negotiation, such as request and response; the processing flow is more complicated, it takes up more system resources, and the transmission efficiency is low, such as figure 2 shown
[0015] 2. The data transmission process requires the joint participation of the sending and receiving hosts. The information is transmitted in data packets. The transmission process of a packet cannot be terminated. At this time, it cannot respond to higher priority data transmission requests, which affects the processing capacity and management quality of the management card host.
[0016] 3. The embedded management data channel is unified by the management unit. When the system is upgraded, the management unit card needs to increase the hardware interface circuit and the board type, which is not conducive to production and maintenance

specific Embodiment 1

[0043] like image 3 As shown, a method for realizing the management of multiple boards and multiple data channels in a communication device, the specific method includes realizing the management of multiple boards and multiple data channels in a communication device based on PCI, board management information and embedded management channel information Both are transmitted by the PCI bus, the PCI controller completes the data transmission physical layer signal processing, and the management unit PCI controller is responsible for bus arbitration. When the number of board cards and the number of embedded management channels change, there is no need to change the backplane connection and the hardware interface of the management unit card.

[0044] All management information is transmitted through the PCI bus, and both the board and the management unit disk have only one physical interface, which simplifies the physical interface type and facilitates design. The bus supports mult...

specific Embodiment 2

[0045] On the basis of specific embodiment 1, the method also includes that the management information storage is stored in a self-defined format, such as address, information type, information length, information content, etc., and is not stored in the form of a package, so that the management unit card can directly Directly read or write management information from board memory without packing and unpacking.

[0046] The PCI bus supports register access, and the management unit can directly read and write to the memory unit of the board card. When the management information needs to be interacted with, it only needs to complete the negotiation through a simple command, and the management unit can directly access the management information, saving the need for data packet encapsulation and unpacking. Packet process, improve communication efficiency.

specific Embodiment 3

[0047] On the basis of specific embodiment 1 or 2, described method also comprises: data transmission process, board card CPU does not participate in data transmission process, directly stores data into corresponding storage unit, just notifies board card CPU to have data update by command or received.

[0048] In addition to the participation of the hosts of both communication parties during the command negotiation period, the data interaction process only needs to be completed by the management unit host, and the board host can perform other tasks, reducing the workload of the board host.

Abstract

The invention provides a method and system for realizing multi-board card and multi-data channel management in communication equipment. The specific method comprises realizing the multi-board card andmulti-data channel management in the communication equipment based on PCI, wherein the board card management information and the embedded management channel information are transmitted through a PCIbus, a PCI controller finishes the data transmission physical layer signal processing, and the management unit PCI controller is responsible for the bus arbitration. All management information is transmitted through the PCI bus, the board card and the management unit disk only have one physical interface, the physical interface type is simplified, and the design is convenient. The bus supports multi-host communication and plug and play, and is convenient for the system capacity enlargement and upgrade and update. The processing on the embedded management data channel physical layer and the data link layer is finished by the board card, the management unit design is unnecessary to change when the board card type is increased or the port capacity is changed, and the production and the systemmaintenance are convenient.

Description

technical field [0001] The invention relates to a method and system for realizing management of multiple boards and multiple data channels, in particular to a method and system for realizing management of multiple boards and multiple data channels applicable to the field of data communication. Background technique [0002] At present, large-capacity communication equipment such as SDH, OTN, and PTN basically adopts a rack structure. A subrack includes multiple boards. In order to facilitate management and maintenance, local and remote management functions need to be provided. The management unit is responsible for collecting and processing local management information and uploading it to the management center. At the same time, the management unit is also responsible for receiving and processing management commands issued by the network management center, and assigning them to corresponding boards for execution. Due to the increasingly complex network structure and the short...
