Netty provides asynchronous, event-driven network application frameworks and tools to quickly develop high-performance, high-reliability network servers and

, event-driven network application frameworks and tools for rapid development of high-performance, high-reliability network servers and client programs.And then we simply understand that this thing is a program, what? Netty is a wrapper for the Java socket NOI. A similar feature is the Apache Mina.In contrast to Tomcat, a Web server, which is primarily about providing Web protocol-related services,

What is Netty?Nature: A jar package from JBossObjective: To rapidly develop high-performance, high-reliability network server and client programsPros: Provides asynchronous, event-driven network application frameworks and toolsPopular saying: A so-so deal with the socketWhat if there's no netty?Ancient: Java.net + java.ioModern times: Java.nioOthers: Mina,grizzly

. Netty is also the most left of the NIO framework, and his robustness, functionality, performance, customisation, and scalability are among the best in its kind. It has been validated by hundreds of commercial/commercial projects, such as the RPC framework Avro for Hadoop, the JMS framework we learned later, the powerful ROCKETMQ, the mainstream distributed communication framework Dubbox, and so on.Netty is a Web

write events. It is usually sufficient for the user to listen to read and write events.At the same time, some extreme situations are considered within the Idlestatehandler: 客户端接收缓慢，一次接收数据的速度超过了设置的空闲时间 . Netty determines whether the outbound buffer is judged by the Observeoutput property in the constructor method.If the outbound is slow, Netty does not think this is idle and does not trigger idle events.

Netty IntroductionNetty is an asynchronous Event-driven Network application frameworkFor rapid development of maintainable high performance protocol servers clients.Netty official website said. It probably means that Netty is an asynchronous event-driven network application framework that enables high-speed developmen

: UDP protocol does not occur in the packet or unpacking phenomenon, because UDP is based on the message sent, the UDP header uses a 16bit to indicate the length of the UDP data packets, so in the application layer can be very good to separate the different data message area.V. Other Due to the possibility of network saturation, how to write large chunks of data efficiently in an asynchronous framework is a special problem.

This article will show you a tutorial on asynchronous use of netty Socket, an Http client demo constructed by Netty, and how to use Netty... the Channel opened by NioClientSocketChannelFactory uses the java Nio Asynchronous Method. According to Unix network programming, IO models can be divided into: Blocking IO, non-blocking IO, IO reuse, signal-driven IO, and a
