还有一种场景就是对方服务器很忙,瞬间有大量client端连接尝试向server建立,server端的listen backlog队列满,server accept不及时((即便不accept,那么在backlog数量范畴里面,connect都会是成功的,因为new conn已经加入到server side的listen queue中了,accept只是从queue中取出一个conn而已),这将导致client端Dial阻塞。我们...
Make sure the server is running before starting the client. After running the client, you should see the data sent by the client displayed on the server console. Conclusion In this article, we have learned how to create a simple Java TCP client-server application using socket programming. We ...
问题2:如果server忙,那么来自client的数据由TCP添�到套接字接收缓冲区,下一个FIN分节也被添�到套接字接收缓冲区,然后等待处理,如果正好此时server应用进程崩溃掉,那么这些数据就丢失掉了,server并没有真正收到,而client也永远不会知道; 2.设置SO_LINGER套接字选项且l_linger为正值时的close ...
private:uint16_t _port;int _listensocket;command_service_t _service; 对于TcpServer主要的变动只是处理业务逻辑上的方法调用,对于真正的调用方法,我们单独启一个.hpp文件。 Command.hpp 对于Command.hpp来说,是处理业务的核心逻辑,那么它要执行的操作就是收到B主机输入的字符串,并且将结果返回B主机。

场景:JAVA的client和server,使用socket通信。server使用NIO。 1.间歇性的出现client向server建立连接三次握手已经完成,但server的selector没有响应到这连接。 2.出问题的时间点,会同时有很多连接出现这个问题。 3.selector没有销毁重建,一直用的都是一个。
