Embodiment

[0018] In this embodiment, a distributed rack system is used. The main control card (MPU card) in the system is the source board, and four line cards (LPU cards) are used as the destination board. The following describes its one-to-many remote procedure call process. (The source board here is an MPU card as an example, but the present invention is not limited to the source board being an MPU card).

[0019] figure 1 Shown is an interaction diagram of one-to-many remote procedure call request messages sent from the MPU card to the four LPU cards. At time t1 on the MPU card, the request1 message (request message 1) of the remote procedure call is broadcasted to the four LPU cards, and each LPU card is processed in parallel. After completion, each LPU card encapsulates a message with the execution result and output parameter (this output parameter is optional), the response message is sent back to the MPU card in unicast mode. The MPU receives reply1 (response message 1, simil...

Abstract

The invention relates to a remote procedure call (RPC) communication mode. The invention aims at the shortcoming of the prior art that the remote procedure call execution time is too long and discloses a distributed system remote procedure call communication method. The technical scheme of the invention is that a source board card and a target board card are included and the distributed system remote procedure call communication method comprises the steps of: a) sending a remote procedure call request message to each target board card in a broadcasting mode through the source board card, b) simultaneously receiving the request messages by the target board card and processing, c) packaging a processing result into a response message through the target board card and sending to the source board card in the single cast mode, and d) receiving the response message sent by the board card through the source board card and feeding a processed result to a caller. The calling time of the invention is linearly uncorrelated to the quantity of the target board card, and can greatly promote the communication property and take full advantage of the remote procedure call in a distributed rack system.

Description

technical field [0001] The invention relates to the communication field of distributed systems, in particular to the communication mode of remote procedure call (RPC). Background technique [0002] The distributed rack system is a communication device with high processing capacity, high forwarding capacity and high access capacity. It is a complete and consistent system externally. Internally, it is necessary to coordinate the coordination of various boards and cards to ensure the consistency of each board. , thus involving inter-card communication among numerous modules and subsystems. The configuration information, status information, and synchronization information between each board need to be completed through inter-card communication, so the requirements for communication performance are extremely high. [0003] In a distributed rack system, if it is necessary to communicate between the main control card and the line card, and it is required to perform some processing...
