A data communication method, device and system

Abstract

The invention is suitable for the technical field of networks, and provides a data communication method, device and system. The method comprises the following steps: creating N port channels, and registering the N port channels to a selector, wherein N is an integer greater than or equal to 1; monitoring port events corresponding to M first port channels in the N port channels through the selector, wherein the M first port channels are port channels which are connected with M communication opposite ends respectively, and M is an integer greater than or equal to 1 and smaller than or equal to N; performing data receiving and transmitting operation according to the monitored port events; after the data receiving and transmitting operation is finished, breaking the connection between the first port channels for performing the data receiving and transmitting operation and the corresponding communication opposite ends. By adopting the data communication method, device and system, multiplexing of port channels is realized based on a JDK (Java Develop Toolkit), a high-performance data communication network framework is provided, and multi-thread high-efficiency data communication among machines can be realized based on the network framework.

Description

technical field [0001] The invention belongs to the field of network technology, and in particular relates to a data communication method, device and system. Background technique [0002] In the process of computer data communication, for the single-thread communication method, only one client can successfully establish a connection at the same time, and other clients cannot connect and communicate with the server until the client communication is completed. The communication process of the client takes a long time, which will cause the connection of other clients to time out. [0003] For the multi-threaded communication method, the server first creates multiple threads, one of which is the main thread, which is responsible for establishing the network connection between the server and the client, and the other threads are slave threads, which are responsible for communicating data with each connected client. communication. In the above-mentioned multi-thread communicatio...
