面向连接的TCP协议要求每次peer间通信前建立一条TCP连接,该连接可抽象为一个4元组(four-tuple,有时也称socket pair):(local_ip, local_port, remote_ip,remote_port),这4个元素唯一地代表一条TCP连接。 1)TCP Connection Establishment TCP建立连接的过程,通常又叫“三次握手”(three-way handshake),可用下图来...
第一阶段是连接建立阶段,这个阶段通过TCP三次握手完成Connection Establishment。 第二阶段是数据传输阶段,第三阶段就是连接结束阶段,这个阶段是通过TCP四次挥手完成connection termination。 在整个connection的lifetime中,Client 和server端的TCP connection端口会经历一系列状态的变化。 TCP Connection State Diagram: 在RFC...

Given that TIME_WAIT affects outbound connection establishment due to the depletion of local port numbers and that these connections usually use local ports that are assigned automatically by the operating system from the ephemeral port range the first thing that you can do to improve the situation ...
1)TCP Connection Establishment TCP建立连接的过程,通常又叫“三次握手”(three-way handshake),可用下图来示意: 可对上图做如下解释: a. client向server发送SYN并约定初始包序号(sequence number)为J; b. server发送自己的SYN并表明初始包序号为K,同时,针对client的SYNJ返回ACKJ+1(注:J+1表示server期望的来自...
This exchange in three phases (three-way handshake) complete theestablishment of theTCP connectioncan now be used to exchange data between the client and server. The client side of the connection is responsible for the connection performs an active connection (active open) while the...

Figure 211: TCP “Three-Way Handshake” Connection Establishment Procedure This diagram illustrates how a conventional connection is established between a client and server, showing the three messages sent during the process and how each device transitions from theCLOSEDstate through intermediate states un...

The effect of copying the configuration on the Internet to the production environment is likely to be counterproductive. This article explains the relevant TCP kernel parameters involved in the three stages of connection establishment, data transmission, and disconnection and gives optimization suggestions....
