The TCP client is responsible for establishing a connection with the server and sending data to it. Let’s take a look at a simple TCP client implementation in Java: importjava.io.*;importjava.net.*;publicclassTCPClient{publicstaticvoidmain(String[]args)throwsIOException{StringserverAddress="127....
2、基于Netty实现RTU接口 本文Java代码,来源于modjn(https://github.com/klymenek/modjn),基于Netty 4.x实现Modbus TCP客户端和服务端(Modbus TCP client/server implementation in Java with Netty 4.x)。 package de.gandev.modjn.example; import de.gandev.modjn.ModbusClient; import de.gandev.modjn.e...

[java]view plain copy step1:重传紧接着那个部分ACK之后的报文段,拥塞窗口等于其减去partial ACK的部分。 step2:对于得到确认的新数据,cwnd++ step3:对于第一个或每一个Partial ACK,重传定时器复位。且每次都重置cwnd = 原cwnd / 2。 NewReno算法中有变量recover,其值为检测到丢包时的最大发送序列号。只有当re...

Time to wait between retries is also arbitrary. The implementation as shown here does not support changing the socket timeout, which is IMO much too long by default. I have modified this in my actual code but don't want to modify the sample code I have posted. ...
