Embodiment 1

[0052] Here only discuss the use of logic programming devices to achieve the mentioned functions, the device example model block diagram such as figure 2 As shown, it is assumed here that there is only one main control board and three business boards, but there can actually be more boards.

[0053] The network port bus can be any bus compliant with the IEEE802.3 protocol that can support network transmission.

[0054] When the MAC address is constructed in a bit mask, the MAC address assigned by design is shown in the following table:

[0055] Board name MAC address Main control board 00:00:00:00:00:01 Business board a 00:00:00:00:00:02 Business board b-net port 0 40:00:00:00:00:04 Business board b-net port 1 80:00:00:00:00:04 Business board c 00:00:00:00:00:08

[0056] The logic programming device only needs to detect the bit[3:0] and bit[40] of the destination MAC address, and does not need to maintain the port and MAC address mapping table. This relationship can be direc...

Abstract

The invention relates to an inter-board communication device and method in distributed equipment. The device includes a main control board and a plurality of service boards, the main control board includes a connected CPU processor and a logic programming device, the service board includes a CPU processor and a network port connected to the main control board; the CPU processor , used to send a message to the logic programming device; the logic programming device is used to receive the message, and analyze the two-layer MAC address of the message, and obtain the MAC address according to the MAC address composition rule of the network port of the service board The corresponding relationship between the address and the service board, and sending the message to the network port of the corresponding service board. The invention is used to solve the problem of complex logic programming in the prior art, simplify the realization of the layer-2 switching function in the logic programming device, take into account the transmission of standard Ethernet, and realize the isolation of messages between service boards Function.

Description

Technical field [0001] The invention relates to the field of network information transmission, in particular to an inter-board communication device and method in distributed equipment. Background technique [0002] In a distributed device, there are multiple boards inside the device, that is, a frame-type device. This device generally consists of a main control board and a business board. [0003] The main control board is mainly responsible for the management and control of the entire equipment, and there is a large amount of inter-board information interaction between it and the business board. In general, the data communicated between the boards does not need to communicate with the external network, and a small local area network is formed between the board and the board. [0004] In order to realize the communication between the main control board and the business board, a device similar to a switching chip will be added to the main control board in the hardware design to under...
