确切地说，TCP/IP协议是一组包括TCP协议和IP协议，UDP（User Datagram Protocol）协议、ICMP（Internet Control Message Protocol）协议和其他一些协议的协议组。TCP/IP整体构架概述 TCP/IP协议并不完全符合OSI的七层参考模型。传统的开放式系统互连参考模型，是一种通信协议的7层抽象的参考模型,其中每一层...
在UDP程序的client端和server端运行 mpstat -P ALL 3 查看CPU使用率,情况特别是client端CPU使用率.注意不要将CPU打满,最好控制在90%以下. 下图是C6.2XLARGE16机型的验证情况截图,可以看到带宽基本可以打满到9G,此时丢包率也很低,client端的CPU使用率大致在90%左右. ...
1、UDP传输工具类(serverclient)UDP不适合传输大数据,所以传输要尽量小。UDP传输中可能会丢包,如果需要可能多次发送同一个包保证包能安全到达;接收端可以对收到的包进行CRC校验,javaviewplaincopypackageorg.sl.udp.beans;.DatagramPacket;/* 处理udp请求的接口* authorshanl*/publicinterfaceIUdpRequestHandler/*解析...
