Problems solved by technology

[0014] Although the method adopts IPC asynchronous sending and the application layer synchronous control of the sender to solve the problem of deadlock between tasks in the multitasking system due to synchronous waiting and the problem of message order preservation, but because the application layer synchronously controls the sending of messages, The waiting process still exists, and the problem of low sending efficiency still exists. Therefore, this method is not suitable for communication between devices with a large number of messages, frequent message interactions between devices, and high communication efficiency requirements.

Embodiment Construction

[0066] Distributed network equipment refers to network equipment in distributed systems such as distributed routers (or switches), and some order-preserving messages need to be transmitted between the distributed network equipment. In order to improve communication efficiency and realize message order preservation, the present invention Mainly adopt the following methods:

[0067] First, the transmission layer between distributed network devices uses IPC asynchronous method to send messages. Since the message sending is asynchronous, this method can solve the problem of deadlock between tasks that are prone to occur due to synchronous waiting in a multi-tasking system;

[0068] Second, the application layer of the sender's network device adopts a selective synchronization control mode, and the selective synchronization control in the present invention refers to:

[0069] Synchronize the control messages between certain distributed network devices that affect the whole world, t...

Abstract

This invention discloses a message transfer method including: determining the necessary transferred sequence-keeping information in distributed network devices, determining the synchronous controlled sequence-keeping information necessary for the applied layer to control and transfer synchronously in the information, at the applied layer, said sequence-keeping information is transmitted to the transmission layer of said network device orderly to be further sent out in terms of the asynchronous sending mode on the transmission layer, among which, the sending of said information is synchronously controlled at the applied layer. Besides, this invention also discloses a related information transfer device.

Description

technical field [0001] The present invention relates to the technical field of data communication, and more specifically, to a message transmission method and device in a distributed system. Background technique [0002] Large-scale communication equipment usually adopts a distributed system processing structure, and a distributed system is generally composed of a main control board and multiple interface boards. Among them, the main control board is responsible for the centralized control and management of the equipment, and centrally processes the common characteristics of each interface board that realizes different services, and then distributes them to each interface board. [0003] The traditional inter-process communication (IPC, Internal Process Communication) generally only realizes the communication between different processes in the same system, and the means used are usually shared memory and messages, so it cannot be applied to distributed systems. However, thr...
