ports and protocols

Senior engineers teach you how to select Open Source protocols Practice open source Now open source is more than just a spirit, and many domestic and foreign companies have actually practiced it. Including FEX, more than 20 open-source products are supported by many front-end developers. The number of stars on GitHub is close to 3000. Therefore, we naturally face the issue of choosing open source protocols

Reprint Address: http://blog.jobbole.com/84429/TCP HTTP UDP:is the communication protocol, that is, the rules of communication, only the two parties in accordance with this rule "speak", the other party can understand or serve.The relationship between TCP HTTP UDP three:TCP/IP is a protocol group, which can be divided into four levels: network interface layer, network layer, Transport layer and application layer.At the network layer are IP protocols,

Network protocols are the basis for the development of the Internet. If we want to control the network well, we must have a clear understanding of network protocols. Here we will explain some elements of the network protocol. A network protocol includes at least three elements: The syntax is used to specify the information format. The format, encoding, and electrical equality of data and control information

The OSI seven-layer model is a standard system and framework for interconnection between different computers or communication systems, including a range of standards and protocols in OSI, such as TCP/IP, UDP, HTTP, and so on, which provide implementation and support for these protocols in Node.js, such as: NET modules provide TCP, Socket encapsulation and support, the Dgram module provides a package and sup

GE switches are still commonly used. So I have studied the full performance solution of the mainstream L2 switches with all-optical ports. I would like to share this with you and hope it will be useful to you. Recently, the F-engine S2200F series all-optical ports, 10-Gigabit L2 switches and F-engine S2200G series all-optical ports, which are independently develo

LAN protocol is the most important part of our LAN. With the coexistence of LAN and Internet. These protocols have also been affected by the deepening of Internet protocols. Computer network applications have been applied in almost all fields of human activity. The core of all network applications is network protocols. Network protocol is a supporting software an

More and more developers and designers want to open-source their products so that others can do more on the basis of their code. The open-source community is also full of vigor. Open-source software exists in all the application fields we can think of (open-source CMS such as WordPress and Drupal ). However, many people do not know about open-source licenses. This article describes several license protocols commonly used in the open-source field and t

, intuitive, and efficient. Due to the large amount of information transmitted by digital videos and limited bandwidth, the compression and encoding of videos, selection of transmission channels and network protocols, and IP Multicast technology (IP Multicast) software Implementation Based on the Windows operating platform has become a key technology in network-based digital video transmission applications. Among them, the choice of transmission chann

languages. By using source code and documents, you can understand the architecture of the entire software and the implementation methods of a specific function. Object Code refers to the object code generated after the source code is compiled, similar to the "class library". It provides various interfaces for others to use. According to my understanding, it is something like common DLL, ActiveX, OCX controls. (I don't know if this is correct) The purpose of these two concepts is to make it clea

Many people may be familiar with the term Router Protocol, especially the rapid development of the network, the Internet Router Protocol is constantly improved, and many new features are also emerging. The wide application of information technology in various fields has promoted the rapid development of information exchange networks. Internet is the biggest beneficiary. The main node and device of the Internet network are routers. The router technology determines data forwarding through routing.

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

reliable data transmission. Network layer: provides connectivity and path selection between two host systems located in geographically diverse networks, and the development of the Internet has greatly increased the number of users accessing information from every site in the world, and the network layer is the layer that manages this connection. Transport Layer: provides port-to-port connectivity. (after masking the lower layer, it can be understood that communication between the

corresponds to the scheme in the Android data tagWww.baidu.com indicates that the domain name corresponds to the host in the data tags indicates the port corresponds to the ports in the data tagCl=3wd=deeplink indicates the path path corresponds to a path in the data tagThese properties are optional, but are also interdependent. If the scheme attribute is not specified for the intent filter, all other URI properties are ignored. If you do not specify

For various reasons, many networks adopt multi-route protocols. This phenomenon is usually caused by merger and acquisition activities, or temporary occurrence during the migration. Many vro hardware manufacturers may use a variety of proprietary protocols to connect with standard protocols. Some routers will run more than one protocol and inevitably receive the

and provides services related to the existing GSM system. Core networks can connect users to various external networks and business platforms, such as circuit switched voice networks and packet switched voice networks (IP voice networks), data network, Internet, Intranet, e-commerce, SMS center, etc. 2. UMTS systems mainly include the following interface types: (1) B interface: MSC (vlr;(2) D Interface: MSC (HLR;(3) E interface: MSC (MSC;(4) GC interface: ggsn (HLR;(5) GJ interface: ggsn (exter
