一种带有断开恢复功能的Socket通信方法

A Socket Communication Method with Disconnection Restoration

Socket是UNIX平台上网络编程的基础,SocketAPI提供了进程之间的通信功能,但如果通信的一方发生故障重新启动,通信连接就会断开,应用层必须显式地重新建立连接才可以继续通信。对传统Socket通信机制进行了综合分析,在保证效率的前提下,提出了一种新型的Socket通信方法。采用这种方法,可以为分布在网络上不同主机上的进程间通信提供具有故障恢复能力的可靠通信。

Socket is the base of UNIX platform network programming, it provides the interprocess communication function, but, if one of the communication parts restores from malfunction, the socket connection will be disconnected and the upper application layer must reconnect explicitly to set up the socket connection again. In this paper, the disconnection exceptions of socket communication are analysed, furthermore a novel mechanism of socket communication is proposed. This method provides the disconnection tolerance for interprocess communication.
