3.1 Http protocol development 3.1.1 basic knowledge HTTP (Hypertext Transfer Protocol) protocol is an application layer protocol based on TCP transmission protocol. Its development is the result of the cooperation between the World Wide Web association and the Internet working group IETF. HTTP is an object-oriented protocol belonging to t ...

Netty's threading model Reactor model Netty's model is based on Reactor mode, so we must know Reactor first. The Reactor model is also called the Dispatch model. When one or more requests are sent to the server at the same time, the server synchronously assigns them to the processing threads of each request. Three roles of Reactor model Ac ...

brief introduction When we introduced channel, we mentioned that almost all the implementations in channel are implemented through channelPipeline. As a pipeline, how does it work? Let's have a look. ChannelPipeline ChannelPipeline is an interface, which inherits three interfaces: channelinboundinvoker, channeloutbooundinvoker and Itera ...

netty(3) – stick pack and half pack problem What is TCP sticky packet and half packet? Suppose the client sends two data packets D1 and D2 to the server respectively. Since the number of bytes read by the server at one time is uncertain, there may be the following four situations. The server reads two independent data packets, D1 an ...

1. Requirements of chat program Through the previous study, we can see that the client and server can interact normally, so can we make a chat applet ourselves? Now we can define some requirements ourselves, such as: 1. After the server receives a message from the client establishment request, we need to push the message to other clients, whic ...

brief introduction The remoting module of RocketMQ is the basis of communication among RocketMQ client, consumer, NameServer and Broker. It is implemented through the netty framework. The inheritance structure of the core class is as follows: The RemotingService interface defines the start(), shutdown(), registerRPCHook() methods. The re ...

brief introduction Channel is not only the channel of data transmission and data processing in netty, but also an indispensable part of netty program. In netty, channel is an interface, which has different implementations for different data types or protocols. Although channel is very important, it is really mysterious in the code. Basica ...

What is Netty 1. Netty is a client server framework based on NIO, which can be used to develop network applications quickly and easily. 2. It greatly simplifies and optimizes network programming such as TCP and UDP socket server, and has even better performance and security. 3. Support a variety of protocols, such as FTP, SMTP, HTTP and ...
