tcp ip illustrated

Repost TCP/IP protocol simple analysis First, TCP/IP and IP are two different protocols. They are divided into different layers in the layer-7 network model. IP is the network layer protocol, and

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 protocols. Now I have a prelimi

Difference between TCP/IP and UDP (reprinted), tcpudp Before analyzing the differences between the two, we should first understand the relationship between the two, The TCP/IP protocol cluster is a network control protocol. Simply put, it is a network protocol. Computers in our network use this protocol cluster for dat

Socket (socket)(turn) What is a socket (socket)?When the application layer communicates data through the transport layer, TCP and UDP encounter problems that simultaneously provide concurrent services for multiple application processes . Multiple TCP connections or multiple application processes may require data to be transmitted over the same TCP protocol port.

TCP/IP, WebSocket and MQTT According to the OSI network layering model, IP is the Network layer protocol, TCP is the Transport Layer protocol, and HTTP and Mqtt are the application layer protocols. Between the three, TCP is the protocol for HTTP and Mqtt at the bottom. Ever

Approaching TCP/IP protocol 1. What is TCP/IP? TCP/IP Protocol (Transmission Control Protocol/Internet Protocol, Transmission Control Protocol/InternetIs the most basic Internet protocol. Before the formation of the Internet, many

, FDDI Data link layer, ATM (asynchronous Transfer mode, asynchronous Transfer Mode), IEEE 802.5 (Token Ring), frame Relay (Frame relay) Network Layer : Responsible for routing data packets between subnets. In addition, the network layer can also realize congestion control, Internet interconnection and other functions. Packet, pack. Typical protocol representative: IP, ICMP, IGMP, IPX, BGP, OSPF, RIP, IGRP, EIGRP, ARP, RARP, x. Transport Layer (Tr

, and such software becomes one of the components of the entire diskless system. Difference: ARP Frame Type code: 0x08086 rarp:0x8035 For RARP, the RARP request is broadcast, and the RARP response is unicast. Each system on the network has a unique hardware address, which is configured by the network interface manufacturer. The RARP implementation of diskless systems is to read a unique hardware address from the interface card and then send a RARP request requesting the

Solutions When the client starts a TCP/IP socket connection to the server, the client usually connects to a specific port on the server and requests the server to respond through a temporary (or temporary) TCP o

You may have heard of the TCP/IP protocol. Do you know what TCP is and what Ip is? In this chapter, we will learn about the most widely used protocol on the network. 7.1 network transmission layeringIf you have passed the computer grade examination, you should have understood the concept of network transmission layeri

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 protocols. Now I have a p

Source: TaubonrenLinks: http://blog.jobbole.com/99694/Since it is a network transmission, involving the interaction between several systems, the first thing to consider is how to accurately locate one or several hosts on the network, and how to carry out reliable and efficient data transmission. This will use the TCP/IP protocol.1.1 TCP/

header and packet data lengthIdentifier: A uniquely identified number used to identify the order of a packet or a fragmented packetFlags: Used to mark whether a packet is a shard, and the values in that domain are used to reorganize the packets in the correct orderSurvival time: Defines the generation period of the packet, minus 1 per routerProtocol: A type used to identify upper-middle-order protocol packets in a packet sequence, such as ICMP,TCP,UD

the difference between IP fragmentation and TCP segmentation 1, MTU (Maximum transmission UNIT,MTU), Maximum transmission unit(1) Ethernet and 802.3 have a limit on the length of the data frame, with a maximum value of 1500 and 1492 bytes respectively. This feature of the link layer is called the MTU. Most of the different types of networks have an upper limit. If the
