tcp ip guide

To be exact: TCP fragmentation should be called TCP segmentation. —————————————————————————————————————————————————————— Difference: 1.IP fragmentation is caused by the fact that the MTU;TCP segment of the network layer is caused by MSS. 2.IP fragmentation is done by the net

(Xee: This IP is definitely not an IP address in connection with TCP!) , also an agreement! What kind of protocol, see the following programming TCP/IP architecture ) Now attach several pictures to see: The network is divided from bottom to top: The physical layer, the data

First, let's take a look at the network level distribution map　HTTP, Socket, TCP the location of the three in the TCP/IP protocol family:With a preliminary understanding, I know that the IP protocol corresponds to the network layer, the TCP protocol corresponds to the transp

1 What's all this? Since it is a network transmission, involving several systems, the first thing to consider is how to accurately navigate to one or several hosts on the network, and the other is how to reliably and efficiently of data transfer. The TCP/IP protocol will be used here. 1.1 TCP/IP protocol group The

TCP/IP is the core protocol of the Internet and also the core protocol of most network applications. Here is a simple summary of the TCP/IP questions I have asked during the previous interview. TCP is defined by RFC793, RFC1122, RFC1323, RFC2001, RFC2018, and RFC2581. (1)

The linux OSI Layer-7 model, TCP/IP protocol stack, and the structure of each layer reveal big secrets. The osi protocol stack When I learn Linux, I know the OSI model even if I am a little cute. What ?! You don't know !!! Okay, this secret is taken away. Thank you ~~~ I,Two protocols (1OSI protocol model (layer-7) International ProtocolPDU: The data unit transmitted between peer-to-peer layers. O

Rules such as how to detect a communication target, where to initiate communication, which language to use for communication, and how to end the communication need to be determine

The network is divided from bottom to topThe physical layer, the data link layer, the network layer, the Transport layer, the session layer, the presentation layer, and the application layer.with a preliminary understanding, I know that the IP protocol corresponds to the network layer, the TCP protocol corresponds to the transport layer, and the HTTP protocol corresponds to the application layer,The three a

Why is there a TCP/IP protocolAll over the world, a wide variety of computers run their own different operating systems for everyone, and these computers are used in many ways when expressing the same message. It is as if God in the Bible has disturbed the accents of people everywhere and made them unable to cooperate. Computer users realize that the computer is only a man-in-the-war and does not play a big

protocol must), but the RFC standard requires that the sender should calculate the test and.UDP verifies and overwrites the UDP protocol header and data, which is different from the IP check and the IP protocol is verified and only overwrites the IP header, and does not overwrite all data. Both UDP and TCP contain a p

network performance. The problems that can be solved are as follows:1. All TCP senders can detect intermediate path congestion early, and proactively slow down the transmission rate to prevent congestion. 2. On the queue forwarded on the intermediate router, ECN marks the TCP message exceeding the average queue length, and continues forwarding, no longer discards the message. The message is discarded and t

Otherwise, an exception "the type initializer for 'Microsoft. samples. BizTalk. Adapter. tcp. Receive. receiveadapter 'threw an exception." will occur during running. Add an adapter After the installation is complete, you need to add the adapter in the BizTalk console to create a host for receiving and sendin

Introduction to TCP/IP and other network protocols 1. TCP/IP is a communication protocol for the Internet. Computer Communication Protocols are descriptions of the rules that computers must comply with in order to communicate with each other. TCP/

What is the TCP/IP protocol. first, the TCP/IP model The TCP/IP protocol model (transmission Control protocol/internet Protocol) contains a series of network protocols that form the basis of the Internet and is the core protocol

One. What are the main functions of the transport layer?Split and reassemble the data streams provided by the upper layer to provide end-to-end transport services for the data flow.two. How does the transport layer differentiate the data flow of different applications? Because, for the transport layer, it only needs to know which service program on the target host responds to the program, without needing to know what the service program is doing. Therefore, we only need to be able to represent t

HTTP protocol: Simple Object Access Protocol, corresponding to the application layer, HTTP protocol is based on TCP connection TCP Protocol: Corresponds to the transport layer IP Protocol: Corresponds to the network layer TCP/IP is a Transport layer protocol that mainly ad

TCP/IP Study Notes (4) 1. UDP protocol UDP is a simple datagram-oriented transport layer protocol. Each output operation of a process generates a UDP datagram and assembles it into an IP datagram to be sent. UDP does not provide reliability.UDP encapsulation format:　 IP header (20) UDP header (8) UDP dat

Network seven layer from the bottom up to the physical layer, Data link layer, network layer, transport layer, Session layer, presentation layer and application layer, the general programmer is the most contact with the application layer and transport layer, and then down is the so-called media layer, not the object of our study.The following is the application layer, Transport layer, network layer, Link Layer Communication protocol overview map. What we often come into contact with are:HTTP pro
