response is implemented through downstream. Channel channels each contain a pair of upstream and downstream, as well as our handlers (Echoserverhandler), as these are encapsulated by channel pipeline, The data flow flows in the pipeline, and each socket corresponds to a channelpipeline.Channelpipeline is the key, and it resembles a Unix pipeline that has the following effects: Keep channelhandlers for each channel, such as Echoserverhandler All the events are going through it.

Netty is a simple example of communication between the client and the server. Netty is based on NIO, and Netty provides high-level abstraction on NIO. In Netty, the Accept connection can be processed by a separate thread pool, and read/write operations are processed by another thread pool. The same thread pool can also

communication framework can be flexibly expanded through Channelhandler;4) High performance, through the comparison with other industry mainstream NIO framework, Netty of the comprehensive energy optimization;5) Mature, stable, netty fixed all of the JDK NiO bugs that have been found, and business developers don't need to worry about nio bugs anymore;6) The community is active, the version iteration cycle

registered to a selector selector, This allows multiple socket objects to be monitored using a single user thread, and when the event occurs, the corresponding socket is searched for read and write operations.Before making a friend of NiO development, you can look at the following example to review the entire process:Threading modelIt says my understanding of multiplexing, mentions that a thread listens to multiple sockets, but if there are many sockets, a thread cannot handle it. In addition,

asynchronous, event-driven Network programming framework and tool that is a NiO-based client, a server-side programming framework that uses Netty to ensure that you quickly and simply develop a Web application, such as a client that implements some kind of protocol, a service-side application. Netty quite simplifies a

Encoding and decoding, or the conversion of data from one specific protocol format to another format. These tasks are handled by components that are commonly referred to as codecs. Netty provides a variety of components that simplify the process of creating a custom codec to support a wide range of protocols. For example, if you are building a Netty-based mail server, you will find that Netty's support for

What is NettyNetty is an asynchronous Event-driven Network application frameworkFor rapid development of maintainable high performance protocol servers clients.Netty is a NIO client server framework which enables quick and easy development of network applications such as protocol s Ervers and clients. It greatly simplifies and streamlines network programming such as TCP and UDP socket server.2. Why Use NettyAncient: Using IO, the modern is NiO, no

Netty Introduction Netty is a Java open source framework provided by JBoss. Netty provides asynchronous, event-driven network application frameworks and tools for rapid development of high-performance, highly reliable network servers and client programs.In other words, Netty
