internet protocol tcp ip properties

We all know that the tcp ip protocol is the basic network protocol. Therefore, the basic transmission in the network relies on this protocol. However, it is also divided into a double-layer structure, so we do not know whether it is clear. So let's take a look at the

communication between hosts, each host must have a unique network address. It's as if every house has a unique door, so it's not confusing when it comes to transmitting data. The network address of the Internet refers to the address number of the computer that is connected to the Internet network. So, in an Internet network, a network address uniquely identifies

physical machine on the LAN to request its IP address from the Gateway server's ARP table or cache.ICMP (Internet Control message Protocol) Internet Controlled message protocol. It is a sub-protocol of the

TCP and IP protocol-header structure (figure)IP protocolThe IP Protocol (Internet Protocol) is a network layer

ObjectiveThe previous blog post simply introduces the HTTP protocol that belongs to the application layer, and this article will learn the HTTP protocol in detail, which is a protocol that must be used in web development. Although I am big data, but learn a little more certainly isThere's no harm in it. National Day holiday 7 days, many people are thinking how to

designers focus on the interconnection of the network, allowing the communication subnet (network interface layer) to adopt existing or future protocols, so this level does not provide a special protocol. In fact, the TCP/IP protocol can be connected to any network through the network interface layer, such as X. Switc

The IP protocol provides unreliable, non-connected datagram delivery services.Unreliable (unreliable): The IP protocol does not guarantee that datagrams will successfully reach the destination, it only provides transport services. When some kind of error occurs, the IP

　　 　 Table 5. IP packages from A to B 　　 In this case, IP addresses are redundant because they do not play any role at all. IP addresses can only increase the processing time and occupy excessive transmission bandwidth. After B receives the package, the IP layer checks whether the destination address in the package

Summary, TCP/IP is the Transport layer protocol, the main solution to the data in the network transmission, socket is the implementation of TCP/IP protocol, is the TCP/

1 ARP Protocol OverviewIP packets are usually sent over Ethernet, but Ethernet devices do not recognize 32-bit IP addresses. They transmit Ethernet packets at 48-bit Ethernet addresses. Therefore, the IP drive must convert the destination IP address to the destination IP add

This article describes how to use domain Name Services (DNS) in Windows XP by configuring the TCP/IP protocol. DNS is an Internet service that converts a domain name to an IP address. On the Internet, when you use a domain name d

transmitted in plaintext; Tcp syn Flooding Attack (SYN Attack; Fraud of spoofing ). Figure 1 For example, network administrators are familiar with the Internet Control Information Protocol (ICMP), which is a basic network management tool for TCP/IP

this level includes the network cable standard and the definition of the network card. (We Don't Need To care about this. We don't need to do it either ), therefore, some books do not place this level in the TCP/IP protocol family, because it has almost no relationship with the TCP/

losing BAOZHONGFA, sorting messages, and so on.The SCTP protocol is designed to transmit telephone signals over the Internet.4. Application LayerThe logic responsible for handling the applicationThe Application layer protocol (or program) may skip the transport layer directly using the services provided by the network layer, such as the ping program and the OSPF

This reference article is mainly used for the diffusion of knowledge points in subsequent articles, in this special backup and diffusion learning Exchange.The internetwork includes: IP, ICMP, IGMP, and protocols that are actually working on the internetwork at the link layer, ARP and rarp, and so on.1.IP protocolEach interface on the Internet must have a unique

This article describes how to use domain Name Services (DNS) in Windows XP by configuring the TCP/IP protocol. DNS is an Internet service that converts a domain name to an IP address. On the Internet, when you use a domain name du

The network is divided from bottom to top : corresponding Physical Layer-- Data Link layer-- Network Layer--IP protocol Transport Layer--TCP protocol Session Layer-- presentation layer and Application Layer-HTTP protocol 1. TCP/

TCP/IP is synonymous with a set of protocols, and it also includes many protocols that make up the TCP/IP protocol cluster.TCP/IP protocol cluster is divided into four layers,
