Recently, I encountered an online alarm: a large number of time_wait servers make it unable to establish a new HTTP connection with downstream modules. During the solution, I checked the classic textbooks and technologies.ArticleTo enhance the

1. TCP establishes the connection (three times handshake) The following two diagrams explain TCP's three handshake processes from the protocol and interface two angles (respectively from the computer network-Shehiren and UNIX Network Programming

To establish a connection:Understanding: Windows and sliding windowsTraffic Control for TCPTCP uses window mechanism for flow control what is a window?When a connection is established, each end allocates a buffer to store the received data and send

Abstract:The Transmission Control Protocol (TCP) designed for wired networks has many incompatibility issues when applied to wireless environments and must be modified. At present, we have proposed several improvement solutions for TCP protocol in

1 .  TCP status of the connectionLet's start by describing the status of the TCP connection during the setup and shutdown process. The TCP connection process is the transformation of the State, and the factors that cause the state to transition

Reasons why a TCP short connection cannot be created due to a large number of TIME_WAIT instances and solutions-BasicsRecently, I encountered an online alarm: a large number of TIME_WAIT servers make it unable to establish a new HTTP connection with

Finally, we finally came to the large header TCP protocol. In order to provide reliable transmission services for the application layer, various mechanisms are designed for tcp to achieve possible errors during transmission, such as packet loss,

This article is next, so if you are not familiar with TCP, but also please take a look at the last part of the "TCP" in the previous chapter, we introduced the TCP protocol header, state machine, data heavy crosses. But TCP to solve a very big thing,
