netty s application

following parameters are available: Protocol of communication Layer---Upper layer protocol of TCP Maximum number of connections Idle Timeout The number of network IO processing threads, which defaults to processor +1. (But many processors are now processing two threads on a single processor, so in subsequent versions of Netty, the default is processor * + 1) The most important, of course, is the host and port, no, how to know

Because one job required to run from one area of Huawei to another, I finally met my great God (Li Linfeng:Netty China promoter, now Huawei Technology Co., Ltd. Platform middleware Architecture and Design Department designer), like the technology I can't wait to communicate with him, the great god of technology is really good, little brother worship, Daniel gave me to explain a lot of design ideas, I met most developers, most of the communication technology, with what technology, then feel very

Netty Study Notes (i)Netty is a high-performance nio framework, and the use of Netty is simpler than writing large amounts of code compared to IO programming. Netty's main function is to be responsible for network transmission, Dubbo,rocket MQ and Elasticsearch use Netty as the network transmission Framework.Netty feat

This time the leader made me familiar with socket development, I spent three weeks to learn the relevant knowledge, including Java socket development, focused on learning Netty this asynchronous non-blocking communication framework.Here I have encountered in the process of learning the useful information collated, for your reference.The first step: Java Native Socket network Development learningFocus on the basic principles of CS communication and tho

in the previous article I described the scenario for message push and a simple Hello world based on the Netty implementation. To better understand the code in Hello World, let me explain some of the concepts and working principles of Netty today, assuming you think this article is a bit boring. Please read the Hello World(i) of Android Netty-based message push sc

Netty is a recent project to use the NIO framework, find a variety of information, found that praised it a bit more, so decided to use it: in fact, the second choice, Mina or Netty or write their own. For Mina, also not familiar, but look at various introductions, seemingly netty work is very good, especially the latest 4.x and 5.x reconstruction, and the use of

1 IntroductionData security is a very important aspect of network communication. In order to support Ssl/tls,java the JAVAX.NET.SSL package is provided with Class Sslcontext and Sslengine. In the Netty framework, I/O data is processed in Channelpipeline by the Channelhandler in the pipeline and forwarded to the next Channelhandler. Naturally, Netty also provides Channelhandler implementation Sslhandler to s

In the previous article, "Android Netty-based message push scheme concept and working principle (ii)", we introduced some of the concept of Netty and working principles of the content, today we first introduce a thing called Channelbuffer.ChannelbufferThe message passing in the Netty must be passed as a vector in bytes, in the form of Channelbuffer. Simply put, y

in the previous article I talked about the message push scenario and a simple Hello world based on the Netty implementation, to get a better understanding of the code in Hello World, today I'll explain some of the concepts and how it works in Netty. If you think this article is a bit boring, please read the "Android Netty-based message push solution HelloWorld"ch

Receiving and sending strings in the Netty-based message push solution for Android (3) In the previous article "Concepts and working principles of the Netty-based message push solution for Android (ii)", we introduced some concepts and working principles of Netty, today we will first introduce something called ChannelBuffer. ChannelBuffer All messages in

[TOC] Example of TCP sticky problem code in NettyNetty will occur in the TCP sticky packet and unpacking problems, of course, in fact, for the former network engineer, the first time to see this noun may be a bit uncomfortable, because in that we are talking about TCP cumulative send and Shard function, but the truth is the same.The code comes from the 4th chapter of the Netty authoritative guide, but I still make some changes to some of the cod

Say so much nonsense, only to mention the transmission of objects, do not know whether you are impatient. It is not realistic to pass the message inside a system without object passing. Let's say, how to pass the object.If you have seen the previous introduction, if you are good at focusing on the essence, diligent thinking. You should also think, as we have said, that Netty's message delivery is flow-based, passing through Channelbuffer, then naturally, object also needs to be converted to Chan

Netty is an asynchronous communication framework based on the JAVA NIO class library, which features asynchronous non-blocking, event-driven, high performance, high reliability, and high customization. In other words, Netty is a NIO framework that can be used to quickly and easily develop Web applications such as client and server protocols. Netty greatly simplif

Before reading the "Netty authoritative guide" book, the 14th chapter describes how to design and implement a simple private protocol, the content is very good, but the author provides the code fragment has a lot of errors, it is impossible to compile correctly.For example Marshallingencoder This class is Netty provides a suitable class of JBoss marshalling, its Encode method is protected, not public, And t

Netty Series (iv) TCP unpacking and gluing one, unpacking, and sticky pack issues(1) A small socket buffer problemIn a stream-based transmission, such as TCP/IP, the received data is stored in a socket receive buffer first. Unfortunately, stream-based transmissions are not a packet queue, but a byte queue. Even if you send 2 separate packets, the operating system will not be processed as 2 messages but only as a series of bytes. Therefore, there is no

maintain its subscript that is perfect. Yes, the Netty framework is for high concurrency, because the number of concurrent access, a little bit of performance optimization, will bring considerable performance improvement effect, Netty mainly from the following two aspects of the implementation of the threadlocal to optimize 1) thread objects directly provide set, Get method so that the thread-local storage

Netty use Embeddedchannel for unit testing For unit testing of Netty Channelhandler, Netty provides embeddedchannel embedded channel to complete this process, which is used primarily to test the legality of inbound and outbound process of data; The channel provides the following common APIs: Writeinbound Write a inbound message to Embeddedchannel
