Method, system and distributed apparatus of communication between processes

Abstract

The invention provides an interprocess communication method, an interprocess communication system and interprocess communication distributed devices, wherein the method comprises the following steps: first role CPUs of various distributed devices are completely connected with each other to form a first layer of broadcast domains; the first role CPUs and various second role CPUs in each distributed device are completely connected with each other to form a second layer of broadcast domains of the various distributed devices; the various CPUs broadcast topology discovery messages in the broadcast domains where the CPUs are positioned and establish the topological connection relationships between the CPUs and adjacent CPUs by utilization of the topology discovery messages received; and the various CPUs perform interprocess communication by utilization of the topological connection relationships of the CPUs. The method reduces the number of occupied ports of the various CPUs, greatly reduces the topological connection information required for storage, and is suitable for topological management of interprocess communication of the distributed devices.

Description

technical field [0001] The invention relates to network communication technology, in particular to a method, system and distributed equipment for inter-process communication. Background technique [0002] Inter-Process Communication (IPC, Inter-Process Communication) technology initially refers to the communication between processes within the same CPU, but with the continuous development of network technology, inter-process communication is gradually developed and applied to distributed devices, distributed A traditional device usually includes a control board and multiple service boards, and each control board and service board has an independent CPU. At this time, inter-process communication refers to the communication between processes in different CPUs in a distributed device. communication, but interprocess communication is still limited to individual peer processes.

Problems solved by technology

Using this topology can achieve inter-process communication within a distributed device. However, with the continuous development of network technology, the number of distributed devices that exist simultaneously in the network is gradually increasing, and inter-process communication across distributed devices is increasingly required. However, At present, there is no way to implement inter-process communication that is suitable for inter-process communication across distributed devices. If the full connection method of each CPU is directly used, when there are many distributed devices in the network, the control board and business of each distributed device The board does not have enough ports to realize the full connection of all CPUs in multiple distributed devices, and each CPU must store the topological connection information of all CPUs in each distributed device, which obviously brings great difficulties to the topology management of inter-process communication. great inconvenience
