The usage of softswitch protocol is described in four special protocols. Next we will give a brief introduction to several main Softswitch protocols, such as H.248/MEGACO, Media Gateway Control Protocol MGCP), and Session Initiation Protocol SIP. Main protocols used by Softswitch The softswitch system involves many Softswitch

A Preliminary Study on WCF-17: the equivalence of WCF data protocols, a preliminary study on wcf-17 protocolsData contract equivalenceFeatures If the client successfully sends data of a certain type to the service or the service successfully sends the data to the client, the receiving end does not necessarily have to send data of this type. The only requirement is that the two types of data protocols sho

How to quickly learn about network protocols and network protocolsI. What is the network protocol? Generally speaking, network protocols are a bridge between networks for communication and communication. Only computers with the same network protocol can communicate and communicate information. This is like the various languages used for communication between people. Only when the same language is used CAN c

Network transmission protocol or communication protocol for shortProtocol) refers to the common language for computer communication. Currently, the most popular computer communication is network communication. Therefore, the "Transfer Protocol" generally refers to the transmission protocol for computer communication, such as TCP/IP and NetBEUI. However, the transfer protocol also exists in other computer forms of communication, such as communication between objects in object-oriented programming

Explanation of ES6 syntax iteration protocols and iterator protocols; explanation of es6 The supplement of ECMAScript 2015 is not a new built-in or syntax, but a protocol. These protocols can be implemented by any object that complies with certain conventions.There are two protocols: the iteratable protocol and the ite

prompt" Window /? You can see the corresponding prompt information. Network Protocol-DHCP protocol (The full name of the DHCP Protocol is Dynamic Host Configuration Protocol). DHCP can automatically assign an IP address to each computer in the LAN, complete the TCP/IP protocol configuration for each computer, including the IP address, subnet mask, gateway, and DNS server. In this way, the Administrator does not need to manually configure the TCP/IP protocol for each computer in a LAN, especiall

protocol used by this file transfer process is called the FTP protocol. File transfer in FTP establishes two TCP connections, respectively, to the control connection to use when sending a transmission request and to the data connection that is used when the data is actually transferred. Remote login (telnet and SSH) is a feature that logs on to a remote computer and enables programs on that computer to run. Remote logins commonly used telnet and ssh two kinds of

Redis Research (13)-security and communication protocols, redis research communication protocols I. Security Salvatore Sanfilippo, author of Redis, once published the Redis declaration, which mentions Redis to be concise and beautiful. Redis does not do much work at the security level.1. trusted environmentThe Redis security design is based on the premise that "Redis runs in a trusted environment". During t

Open source is already widely used in today's software industry, but does open source mean that users can do whatever they want to do with open source code? The answer is no. Open-source sports also have their own game rules and ethics. Failing to comply with these rules will not only damage the healthy development of the open source movement, but also cause reputational and market losses to violators, and more likely fall into legal disputes and compensation. There are many open-source

The routing information protocol, that is, the RIP Protocol. This protocol is one of the earliest in the routing protocol family. It plays a fundamental role in the development of some subsequent protocols. So let's compare several protocols. The Routing Information Protocol (Routing Information Protocol) is an ancient Routing Information Protocol based on the distance vector algorithm. It selects the optim

OC-Concepts and usage of protocols, oc-concepts of protocols In the previous article, we introduced the class extension in OC: Extend. The protocol in OC is equivalent to the interface (abstract class) in Java, but the name in OC is more vivid, because when we are learning interfaces in Java, it can be seen that the interface is equivalent to a contract (Protocol), marking its implementation class. Of cour

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

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 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

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

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

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
