In the previous code, a C# .net TcpClient implemented the full-duplex communication protocol_tcpclient protocol_Green Lemon 676’s Blog-CSDN Blog We have implemented the heartbeat of TCP and introduced the full-duplex communication protocol. Today we will take you to understand what TCP packet immersion is and how TCP prevents packet immersion. So let’s make a long story […]

Long connection, short connection, heartbeat mechanism
Long connection, short connection, heartbeat mechanism The relationship between HTTP protocol and TCP/IP protocol HTTP long connections and short connections are essentially TCP long connections and short connections. HTTP is an application layer protocol, using TCP protocol at the transport layer and IP protocol at the network layer. The IP protocol mainly solves network routing […]
12 | Invalid connection: use Keep-Alive or apply heartbeat to detect?
In the previous article, we talked about how to use close and shutdown to complete the closing of the connection. In most cases, we will prefer shutdown to complete the closing of the connection in one direction. After the other end has finished processing, we will complete the other one. Directional closure. In many cases, […]

rabbimq’s java.net.SocketException: Analysis of Connection reset and MissedHeartbeatException
1. Foreword The rabbitmq message queue is connected to the android front-end to handle business. The mobile network environment is complex and the network signal is unstable, which may cause frequent disconnection and connection of mq. In the log, it is found that there are many such logs, java.net. SocketException: Connection reset. Next, we will […]

TCP socket heartbeat packet sample program
When developing games, you often need to implement your own heartbeat mechanism at the application layer, that is, regularly send a custom structure (heartbeat packet) to let the other party know that you are still alive to ensure the validity of the connection. In the TCP socket heartbeat mechanism, heartbeat packets can be sent from […]
