tcp ip guide

TCP/IP protocol (Transmission control protocol/internet Protocol Transmission Control Protocol/Internet Interconnection Protocol) TCP/IP is a protocol Stack, including TCP, IP, UDP, ICMP, RIP, TELNET, FTP, SMTP, ARP, and many othe

Recently work needs themselves in the card embedded TCP/IP protocol stack, because after all, SCM performance is limited, complete TCP/IP stack is very large, so can only be ported simplified, has been successfully ported LWIP protocol stack to the project board, but the boss said the stack is too cumbersome to write,

The network is divided from bottom to top: The physical layer, the data link layer, the network layer, the Transport layer, the session layer, the presentation layer, and the application layer. For example, 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 are inherently no

During this period, I read volume 1 in "TCP/IP details". The biggest feature of this book is that it uses the tcpdump program to capture various network packages, this gives us a definite understanding of the protocols and Algorithms in each layer of the network. It is the protocol discussed in this book and its hierarchy. 1. TCP/

The TCP/IP protocol workflow is as follows: On the source host, the application layer transmits a string of application data to the transport layer. The transport layer truncates the data stream of the application layer into groups, and the TCP header forms the TCP segment, which is sent to the network layer. At the ne

media in the network is different, it is better than a long pipe, which is composed of different water pipes of different thickness (different MTU). The maximum water volume of the pipe is determined by the finest water pipe in the middle. For upper-layer protocols at the network layer (here, the TCP/IP protocol family is used as an example), they do not care about the width of the "water pipe". They thin

This is a creation in Article, where the information may have evolved or changed. Go language TCP/IP network programming At first glance, connecting two processes through the TCP/IP layer can be scary, but in the go language it may be much simpler than you think. Application scenarios for sending data at the

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 address of the Ethernet network. There is a stat

The protocol addressing mechanism mentioned above is simple, the transmission speed is slow, it is not suitable for the data transmission of large range and large flow, therefore, it is applied to the interior of the equipment (such as IC, between circuit board and Circuit board). The TCP/IP protocol stack physical layer uses the fiber/coaxial cable for the transmission medium, fast transmission rate, (up t

TCP and IP protocol-header structure (figure)IP protocolThe IP Protocol (Internet Protocol) is a network layer Protocol used on the Internet. TCP, UDP, ICMP, and IGMP data are all sent in the IP data format. The

University Learning Network Foundation when the teacher said, the network from the bottom up into the physical layer, Data link layer, network layer, transport layer, Session layer, presentation layer and application layer. Through the 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 correspond
