tcp global order status

in 2000 XP 2003, and the default value is 10 in Vista ). 3. The client has crashed but has been restarted.In this case, the server will receive a response to its survival detection, but the response is a reset, causing the server to terminate the connection. 2 hours of free time is too long for applications. Therefore, we need to manually enable the keepalive function and set reasonable keepalive parameters. The global settings can be changed to/etc/

TCP connection status explanation and troubleshooting By understanding the status of TCP, We Can troubleshoot and locate network or system faults. (Summarize the content on the Network) 1. TCP status LISTENING: listens for connect

In the TCP/IP protocol, backlog analysis and settings, and TCP status changes. In the TCP/IP protocol, the first section describes how to set the backlog value. What is this value? We all know that TCP requires three-way handshake when establishing a connection. But if the t

respond to the other side with the RST packet, this will be considered an error by the other party (in fact, this is a normal connection close process, not an exception ).2) in order to make the old data packet disappear due to network expirationTo illustrate this problem, we first assume that the TCP protocol does not have a time_wait status limit, and then ass

TCP status ConverterEstablishing a TCP connection TCP is a connection-oriented protocol. Before sending data to the other party, a connection must be established between the two parties. This section describes in detail how a TCP connection is established and how it is termi

three different functions.(1) "TCP established hash table" is connected to store the hash table (including connections in other non-established States). When a new packet is sent, is used to locate the connection to find the survival status.The bucket of the hash table contains the sockets in TIME_WAIT status and normally active sockets. The size of the hash table depends on the memory size of the operatin

TCP/IP makes the world a global village The TCP Connection established by the TCPIP protocol is terminated on the earth. Humans are very small and distributed in every corner of the world. With the development of science and technology, people can now easily communicate with their loved ones and friends thousands of miles away in real time to get and share what

relieved. But the source side learned that the network is no longer congested and began to increase the speed of transmission, and eventually caused the network congestion, and this phenomenon will often go on and on, so that in a period of time the network in Network utilization (NET utilization) very low status, reduce the overall throughput ( Throughput), this is known as the "TCP

talk about the HTTP protocol, let's briefly talk about the TCP three handshake process, in the following blog we will be on the TCP and IP protocol details, this blog will be a simple chat on the basis of the HTTP protocol.The TCP protocol is located in the transport layer, and in order to ensure the reliability of th

By understanding the various states of TCP, we can help to troubleshoot and locate network or system failures. (Summarize content on the network)1. TCP StatusLISTENING: Listens for connection requests from a remote TCP port.First, the server needs to open a socket for listening, the status is listen. To provide a servi

Web Product performance Testing, there are many TCP connection problems, but also because of this problem, resulting in performance instability and so on, the data transmission between the client and server, and the transition between the connection state, which state is the normal state, which state is abnormal state, how to locate these problems, As well as the common tools, today a simple summary of these questions; 1
