Embodiment 1

[0052] Here we only discuss the use of logic programming devices to realize the mentioned functions. The block diagram of the device example model is shown in figure 2 As shown, it is only assumed that there is 1 main control board and 3 service boards, and there may be more boards in reality.

[0053] The network port bus may be any bus conforming to the IEEE802.3 protocol that can support network transmission.

[0054] When the MAC address is constructed in the form of a bit mask, the MAC address assigned by the 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 Service board b-network port 0 40:00:00:00:00:04 Service board b-network 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 ...

Abstract

The invention relates to an inter-board communication device and method in distributed equipment. The device comprises a master control board card and multiple service board cards, wherein the master control board card comprises a CPU processor and a logic programming apparatus in connection; each service board card comprises the CPU processor and a network port for connecting the master control board card; the CPU processor is used for sending a message to the logic programming apparatus; the logic programming apparatus is used for receiving the message and analyzing the two-layer MAC address of the message, thereby obtaining a corresponding relation of the MAC address and each service board card according to an MAC address constitutive rule of the network port of each service board, and then sending the message to the network port of the corresponding service board card. The communication device disclosed by the invention is used for solving a problem that the logic programming is complex in the prior art; the transmission of the standard Ethernet is considered when the two-layer exchange function in the logic programming apparatus is simplified, and the message isolation function between the service board cards can be realized.

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 chassis-type device, which generally consists of a main control board and a service board. [0003] The main control board is mainly responsible for the management and control of the entire device, and there is a large amount of inter-board information interaction between it and the service board. Generally, 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 boards. [0004] In order to realize the communication between the main control board and the service board, a device similar to a switching chip is added to the main control board in the hardware design, which is responsible for th...
