Big Google is quic to see if it can combine the advantages of both protocols, while achieving low latency and high reliability and applying them to higher-security protocols. This article is to introduce the QUIC protocol in detail. Speaking from the TCP protocol Currently, the data transmission of the Web platform is based on the
used to remotely determine if a host is present on the network. A ping program is a basic tool for testing the connectivity of two systems. It uses only the ICMP echo request and Echo reply message, without passing through the transport layer tcp/udp. Ping servers typically implement ICMP functionality in the kernel.The accessibility of a host on a network depends not only on whether the IP layer is available, but also on what
Different TCP/IP layers provide different security. For example, a virtual private network is provided at the network layer and a secure connection service is provided at the transmission layer. The following describes the security of TCP/IP at different levels and the methods to improve the security of each layer.I. Security at the Internet LayerThe idea of standardizing security protocols on the Internet

The process of 3 handshake when the TCP protocol connection is established. This paper briefly describes the 3-time handshake process of TCP protocol connection establishment.According to the TCP header, the following 3 packages are in the order of the connection
Finally, I saw the TCP protocol. This is the most important and exciting part of the TCP/IP explanation. It takes a lot of effort to read it. The previous TFTP and BOOTP are both simple protocols, so you don't need to take notes.TCP and UDP are on the same layer-transport layer, but the most difference between TCP and
TCP/IP protocol ----- excellent notes, tcpip protocol -----1. Introduction The TCP/IP Protocol is not a single TCP Protocol or an IP Protocol
TCP vs. UDP differencesTCP---Transmission Control Protocol, providing a connection-oriented, reliable byte-stream service. Before the customer and the server Exchange data with each other, a TCP connection must be established between the two parties before the data can be transferred. TCP provides time-out re-send, dis
the Ethernet receive this frame and check the target address. If the target address and network adapter address are the same, the adapter software processes the received frame and transmits the data to the higher layer in the protocol stack. Chapter 2 Internet Layer Addressing and sending-- In a selected route network, the TCP/IP software uses the following policy to send data on the network: 1. If the
positive offset, and the ordinal number is summed, only if the URG flag is placed 1 o'clock the emergency pointer is valid. The emergency mode of TCP is a way of sending an emergency data to the other end.Maximum message Length (MSS): The most common optional fields, each of which indicates this option through the first message segment of the communication (the segment in which the SYN flag is set for establishing the connection). It indicates the ma
overturn. My ideal is to be a knowledgeable person with a wealth of professional knowledge, enough to deal with problems at work. In addition to work, you can read books to improve your temperament. 1. what is TCP/IP? If you want to know a person, you can chat from the group where he belongs. Our HTTP protocol is a member of the TCP/IP
TPC/IP Protocol is a Transport layer protocol, which mainly solves how data is transmitted in the network, and HTTP is the application layer protocol, which mainly solves how to wrap the data. regarding the relationship between TCP/IP and HTTP protocol, the network has a re
confirmation after receiving the UDP message. Although UDP does not provide reliable delivery, in some cases UDP is the most efficient way to work. (2) Transmission Control Protocol TCP (transmission-Protocol) TCP provides connection-oriented services. TCP does not p
About portsCommunication between any two hosts on the internet is from one end to the other, also known as end-to-end communication.What is a port?Modern operating systems are equipped with many applications, information to my computer how do I know this message is passed to my QQ application? My QQ program is responding but my MSN did not respond to it?The reason: My system has a number of port numbers, each application process is bound to a unique local port number, so that each program is bou
The difference between TCP protocol and UDP Protocol (RPM)First we find out that the TCP protocol and the UCP protocol and the TCP/IP protocol
I. TCP/IP background and introductionIn the 70 's, with the development of computer technology, computers users realized that it was necessary to connect computers from all over the world to play a more important role in computer. But the simple connection is not enough, because the computer can not communicate. Therefore, the design of a common "language" to communicate is necessary to be less, then the TCP
I. Introduction to the TCP protocolTCP, full name transfer Control Protocol, the Chinese name is the transmission protocol, it works in the OSI Transport layer, providing reliable connection-oriented transport services.The main task of TCP is to establish a connection and then receive and transmit data from an applicat
Protocol: rules, standards, or conventions established for data exchange (communication) in the network. (= Semantics + syntax + rules) TCP/IP has become an industrial standard for Internet communication. TCP/IP model: TCP protocolIs a connection-oriented reliability transmission
