Escape characters in communication protocols and escape characters in communication protocolsEscape characters in communication protocolsPurpose: make the communication content more secure and reliable in the communication protocol.For example: if you need to customize a communication protocol, the most basic thing you need is a frame header and frame tail flag, only the recipient of the communication knows when the communication starts and ends. Assu

the message as a response, as shown in the following figure. Each network application has its own application-layer protocol, which defines the format and sequence of messages exchanged between processes, as well as actions taken when sending or receiving messages. 　　Figure 1: Communication with each other should be with The application layer is a good place for us to start studying the agreement. We are already familiar with many applications that rely on

The foundation of the network is the establishment and application of many computer network protocols. So how can we understand this concept? The following describes the overview of computer network communication protocols. Network Communication Protocol (Network Communication Protocol )) it is a set of definitions of the Information Format for communication between computers and the transfer content that c

How should we understand network communication protocols? Can we fully master the increasingly complex network structures? We need to rely on network communication protocols for learning and understanding. Network Communication Protocol (Network Communication Protocol )) it is a set of definitions of the Information Format for communication between computers and the transfer content that can be accepted by

Comparison of common communication protocols in Java--Reprint:Compare RMI,Hessian,Burlap,httpinvoker,Web service The transmission performance of 5 kinds of communication protocols in different data structures and different data volumes.1. IntroductionRMIIs the Java language itself provides a remote communication protocol, stable and efficient, is the basis of EJB. However, it can only be used for communicat

The reason why routers can run normally is the result of a lot of different protocols working together, why can the protocols coexist without affecting each other? This is what the following is about, the concepts of routing protocols running. VRF: One of the security initiatives of routing protocols is routing isolat

RFC2616).Before 1.1, there were two versions of "0.9 and 1.0", with HTTP 0.9 "not" widely used, and HTTP 1.0 being widely used.In addition, it is said that the IETF will release the HTTP 2.0 standard next year. I'll wait and see.2. The relationship between HTTP and TCPSimply put, the TCP protocol is the cornerstone of the HTTP protocol--http protocol needs to rely on the TCP protocol to transfer data.In the network layering model, TCP is called the Transport Layer protocol, and HTTP is called t

layer:Routers, layer three switches Transport Layer:Four-layer switch, also has a router working on layer four T the CP (transmission Control Protocol) and UDP (User Datagram Protocol) protocols belong to the Transport layer protocol. TCP provides reliable data transmission in IP environment, and it provides services including data transfer, reliability, effective flow control, full duplex operation and multiplexing. Send through connection-oriented,

The common understanding of TCP/IP network protocols was developed some time ago. network programming was involved and the development process was smooth. However, after the task was completed, I always felt a bit confused. The main reason is that you are not familiar with network protocols and are not clear about some concepts. Later, I spent some time learning about these network

The WAN protocol is relative to the LAN protocol, and the Internet can be identified as a wide area network. Then the relevant agreement is well understood. is inseparable from the OSI model. Here are a few typical protocols. To everyone as a reference. The WAN Protocol is a three-tier operation at the bottom of the OSI Reference Model, which defines communication on different WAN media. Mainly used for wide area network communication

With the development of the Internet in China, the connection between ISP service providers and Internet is also changing. On a network connection, from a single connection to the Internet via multiple telecommunications companies, in terms of routing protocols used, from the use of static routing protocols to the use of BGP (Border Gateway Protocol). How does the ISP deploy the BGP routing protocol rationa

Introduction to TCP/IP network protocols Some time ago I made a development, involving network programming, and the development process was quite smooth, but I always felt a bit confused after the task was completed. The main reason is that you are not familiar with network protocols and are not clear about some concepts. Later, I spent some time learning about these network

NGN features a complex converged network based on multiple IP technology vendors, multiple technologies, and different architectures. Softswitch plays an extremely important role in controlling such a heterogeneous network. Control is implemented through protocols. The main Protocols involved in implementing Softswitch include H.323, H.248/MEGACO, SIP, SIGTRAN, and BICC. Check five major

The main reason is that you are not familiar with network protocols and are not clear about some concepts. Later, I spent some time learning about these network protocols. Now I have a preliminary

Objective-C Protocols, objective-c Objective-C Protocols 1.1 Formal Protocols A formal protocol (like an informal protocol) is a named list of methods and properties. Formal protocol (like informal protocol) is a list of names of a series of methods and attributes. However, a formal protocol requires that you explicitly adopt it. Formal protocol requires you to e

Various computer communication protocols: L Protocol: behavior and specification in Network Communication L protocol three elements: 1. Syntax: the sender sends data according to certain rules 2. Semantics: the recipient's computer can read the received information. 3. timed relationship: After receiving the message, you must send a response to the recipient. Common network protocols: 1. netbe

analysis protocols, and configuring user-specified decoding and tracing of TCP streams. statistics--includes a menu item that displays multiple statistics windows, including a summary of capture packages, protocol hierarchy statistics, and more. help--contains reference content for secondary users. such as access to some basic Help files, a list of supported protocols, user manuals. Online access to some w

HTTP proxies are the most classic and most common proxy protocols. Its use is very extensive, commonly seen in the company intranet environment, the General staff need to configure an HTTP proxy browser to access the Internet. At first, HTTP proxies were also used to climb g*w, but because the g*w was evolving, ordinary HTTP proxies had long been invalidated. However, there are still many people using plaintext HTTP proxy protocol combined with softwa

The use of routing protocols plays an incomparable important role in network operation. We know that it is divided into many small types. Today, we will introduce the dynamic routing protocol. Dynamic Routing Protocol is the main method used by routers in network layer forwarding groups. The network is a very complex system, and many technologies exist together, at the same time, each technology follows a protocol. Dynamic Routing Protocol plays an im

We use the Internet every day. Have you ever wondered how it is implemented? Billions of computers around the world are connected together and communicate with each other. One Network Card in Shanghai sends a signal, and the other network card in Los Angeles actually receives the signal. The two actually do not know the physical location of the other. Do you think this is amazing? The core of the Internet is a series of protocols, called Internet
