tcp 连接的11种状态–转载
?
一、Linux服务器上11种网络连接状态
?、LAST_ACK:被动关闭端一段时间后，接收到文件结束符的应用程序将调用CLOSE关闭连接。这导致它的TCP也发送一个?FIN,等待对方的ACK.就进入了LAST-ACK .?/* The remote end has shut down, and the socket is closed. Waiting for acknowledgement.?等待原来发向远程TCP的连接中断请求的确认?*/
9)、TIME_WAIT:在主动关闭端接收到FIN后，TCP就发送ACK包，并进入TIME-WAIT状态。/* The socket is waiting after close to handle packets still in the network.等待足够的时间以确保远程TCP接收到连接中断请求的确认?*/
4、JAVA1.6的相关参数说明:
