Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] Fig. 1 shows the schematic composition diagram of an embodiment of the inter-board communication system in the present invention, including two boards with inter-board communication: single board A and single board B, and the needs of one board from the board-to-board communication The message forwarded between the boards is forwarded to the external switching device of the other board of the inter-board communication, and the external switching device is connected to the single board A and the single board B through the external link I and the external link II respectively. The reason why it is called an external link is to distinguish it from the internal channel between board A and board B in the system. Of course, there may be more than one external link between the external switching device and board A or board B. The corresponding port of the ex...

Abstract

The invention discloses an inter-board communication method which comprises: connecting a single board of both parties for the inter-board communication with an external switching apparatus via an external link, transferring a message to be transmitted among the boards to the external switching apparatus via the external link, and transferring the message to the single board of the other party by the external switching apparatus using the external link. The invention also discloses an inter-board communication system. With the invention, the retransmission of the message among the single boards is completed by the external link and the external switching apparatus, without occupying the bandwidth of the intra-system channel and changing the structure of a system hardware platform. The invention can increase the bandwidth of th inter-board communication channel and solve the problem of insufficient bandwidth of the inter-board communication channel inside the system.

Description

technical field [0001] The present invention relates to the communication field, in particular to an inter-board communication method, system and device. Background technique [0002] In many hardware platform architectures, in order to realize inter-board communication, a hub is integrated inside the system or a compact peripheral component interconnect bus (Compact Peripheral Component Interconnect, CPCI) is used as an internal channel. The bandwidth of the internal channel is very limited. If a large amount of inter-board data needs to be transmitted in the system, the bandwidth will be insufficient. Especially when control messages and data messages share an internal channel, if there is a burst of inter-board data messages within a certain period of time, it is likely to block the internal channel, affecting the inter-board transmission of control messages, and causing the system to fail run. [0003] In order to solve the problem of insufficient channel bandwidth in ...
