The RSVP Resource Reservation Protocol may seem vague to many people. Therefore, this is a type of communication rule on the Internet. Its working mode mainly protects link sharing. Now let's take a detailed look at its basic situation. Resource Reservation Protocol, RSVP) is a set of communication rules that allow one source to play multiple receivers for videos and other high-bandwidth information) the ch

on a single host, things change as they move any workload that runs in the data center. Simply put, tools are becoming increasingly bandwidth-intensive, which was unpredictable 10 years ago. Spanning Tree Protocol Over the years, researchers have tried to control network problems by using the Spanning Tree Protocol (SPT), which usually works well, despite the successive challenges posed by many new protoco

A protocol defines a set of standards for methods and attributes without specific implementation. The Protocol can be implemented (or followed) by classes and struct ). protocol SomeProtocol { // protocoldefinition goes here } struct SomeStructure: FirstProtocol, AnotherProtocol {// structure definition goes here}class SomeClass: SomeSuper

, like the production line of the workshop, into a large need to deal with raw materials, through different operating stations, a layer of cutting, packaging, to the end of time has become a lot of exquisite small products.about the network layer.The network layer has different protocols, such as IP and ICMP, the difference is that the data transmitted from the upper layer according to what format to cut, and then again when the package to follow the guidelines are different.ICMP is the

From: https://www.cnblogs.com/Jadie/p/6877392.htmlNo status meaning:　stateless means that the protocol has no memory function for transactional processing . A lack of state means that the preceding information must be re-transmitted if the subsequent processing requires the previous information, which may result in an increase in the amount of data sent per connection. On the other hand, when the server does not need the previous information, the resp

7.1 Introduction Internet Protocol (PROTOCOL,IP) is the transport mechanism used by the TCP/IP protocol cluster at the network layer. IP is an unreliable non-connected datagram Protocol-the best effort to deliver (best-effort delivery) services.7.2 Data Report The grouping of network layers is called datagrams (datagr

The content includes the principles of the Http protocol, Http request information, Http response information, and Http protocol status code. 1. Basic principles of Http: A client sends

A small application using the timer, singleton and Protocol (2), Timer Protocol In the previous article, I wrote a simple timer, which can also run properly. But now there is a problem, like the Timer Program on our mobile phone. Even when switching to the alarm clock or world time, the timer must still be running later. We can't do that just now. Because we have exited the timer interface when converting o

Hyper Text documents contain hyperlinks that point to other resources. Hypertext document is the foundation of World Wide Web (www. The HTTP protocol solves the problem of file transmission. HTTP is an application layer protocol, mainly based on TCP protocol (occasionally UDP can be used as the underlying layer ). It is popular with the development of the World W

Basic concepts of Protocol (PROTOCOL)The Declaration of a Protocol looks more like an interface to a class in Java, but unlike an interface: a protocol has no parent class and cannot define an instance variable.A protocol is a special programming structure used to declare a

Win7 flagship system How do I reinstall the TCPIP protocol recovery network? Where's the Win7internet protocol? After cleaning up the files and software on your computer, you can't connect to the network properly, which is mostly caused by the destruction of the TCP/IP protocol during computer operation. We need to reinstall the TCP/IP

Introduction: Before 1990, the hierarchical model dominated by data communication and networking literature was the Open Systems Interconnection (open system Interconnection,osi) model, and now the TCP/IP protocol family became the dominant commercial architecture. An OSI seven-layer model 1.1 Physical Layer The mechanical and electrical specifications that relate to the interface and the transmission media are responsible for moving bits-by- bit from

The previous article has introduced the composition of the Protocol. A protocol generally has the following features: protocol header + Length + Data + verification. The text format can intuitively define that carriage return and line feed are the end of the Protocol, therefore, we can omit the Data Length and add the

The UDP protocol is also an unreliable transport protocol compared to TCP. So what is the occasion to use the UDP protocol:1. Efficient and reliable environment2. Because the UDP overhead is small (1) does not need three handshake 2) the transmission process does not need to confirm 3), it is appropriate to communicate in a light-weight environment, such as TFTP,
