System and method for implementing communication between distributed system boards

Abstract

This invention discloses a system and a method for realizing inter-plate communications in a distribution system, in which, an inter-plate communication switch chip initial module configures all combinations of mono-plates and sends them to the chip based on the port connection relation between the inter-plate communication chip and the mono-plate and an adaptive module of R-T packets of the inter-plate communication operates on the plate to compute packing the Ether net frame to be sent, a realize module of the T-R packet operates on the plate too to write the Ether net frame to be packed into the switch chip then to be sent to a destination mono-plate.

Description

technical field [0001] The invention relates to a system for realizing inter-board communication of a distributed system, in particular to various routers, switches and other equipment. The present invention also relates to a method for realizing inter-board communication in a distributed system by using a combination of unicast, multicast, and broadcast technologies to complete the inter-board communication at one time, especially related to the communication between boards of various distributed systems. message processing. Background technique [0002] The distributed system consists of a main control board (generally a protocol processing board and a switching fabric board integrated board, divided into active main control board and standby main control board) and various service line cards. A large amount of information interaction is required between various boards in the system, including the synchronization information from the main control board to the line card, s...

Problems solved by technology

[0008] The above method, that is, the point-to-point communication method, has obvious defects when it is applied to the in-band communication mode or the out-of-band communication mode: the active main control board often needs to synchronize a large amount of information to multiple line cards and the standby main control board at the same time, and most of these messages It is public. If you use point-to-point transmission, you need to copy multiple copies or send it serially, which wastes a lot of inter-board communication bandwidth, and at the same time repeatedly occupies the resources and efficiency of the processor of the main main control board.

In an environment with a large amount of real-time information, messages cannot reach each line card in time, resulting in slow system response and performance degradation of the entire distributed system

It can be seen from the above introduction that the unicast point-to-point communication between boards cannot cope with the application of one board sending messages to other boards, which not only wastes resources, but also reduces efficiency. Congestion of the communication channel
