security, TCP tells the recipient that he wants to receive the first byte serial number of the next packet. 4-1. The offset is 4 bits, similar to the IP address, indicating the number of 32 bits from the header. 4-2. Retain 6 bits. if not used, set it to zero. 4-3. URG-When URG = 1, the emergency pointer field is valid. It tells the system that there is urgent data in this packet segment and should be tran

The socket can support different transport layer protocols (TCP or UDP), which is a TCP connection when the connection is made using the TCP protocol.The socket is an abstraction layer between the application layer and the transport layer, which abstracts the complex operations of the TCP/

, uninstall the NIC Driver, reinstall it. 6. check whether it is difficult to enable it. 7. Restart the server. (windwos is amazing.) How to fix Winsock: The computer cannot access the network and the system prompts "query the tcp ip settings for this connection failed, cannot handle "reinstallation of NIC Driver and re-installation of TCP/

by the application layer of the other system. For example, a PC program communicates with another computer, where one computer uses an extended 210 binary interchange (EBCDIC), and the other uses the U.S. Information Interchange Standard Code (ASCII) to represent the same characters. If necessary, the presentation layer enables conversion between multiple data formats by using a pass-through format. 7. Application layer: The OSI layer closest to the user. This layer provides network services fo

Retain 6 bits. if not used, set it to zero. 4-3. URG-When URG = 1, the emergency pointer field is valid. It tells the system that there is urgent data in this packet segment and should be transmitted as soon as possible (equivalent to high-priority data ).4-3. confirm that the bit ACK is valid only

Linux is a major operating system in many enterprises and companies. So how can we build the tcp ip protocol stack on this system? Next, let's take a detailed look at the component process of the Linux tcp ip protocol stack. Analy

From the good to the beginning, to now, more than a year to hold down.

This chapter describes the network layer addresses used in Interent, also known as IP addresses. Each device connected to the Interent has at least one IP address. The IP address is also required for devices that are used in a private network based on the TCP/IP protocol. In

It tells the system that there is urgent data in this packet segment and should be transmitted as soon as possible (equivalent to high-priority data ).

The current operating system basically implements the TCP/IP protocol. The TCP/IP protocol stack is divided into five layers: Application Layer: A group of common applications provided to users, such as telnet, FTP, SMTP, SNTP, DNS, and HTTP, which have a port to identify. T

Previously, the data transmitted in the network is not clear, by consulting the relevant data, summed up the TCP and UDP and IP message format: TCP Message Format: (Reproduced from http://wenku.baidu.com/view/04b0d780e53a580216fcfeaa.html in the picture above) SOURCE port: The port number of the sender of the data. Destination port: The port number of the data

The Windows implementation of the TCP/IP protocol is built on the OSI foundation of the previous blog post. User Configuration is implemented by Ws2_32.dll and some other service provider DLLs, where Ws2_32.dll is a framework that can accommodate many service providers, which are actually the implementations of various protocols, such as the more common TCP/
