Two types of transport protocols: TCP,UDPTCPTCP is the short name of Transfer Control Protocol , which is a connection-oriented protocol that guarantees reliable transmission .In the TCP/IP protocol,IP layer is mainly responsible for the location of the network host, the routing of data transmission, by the IP address can uniquely determine a host on the Internet . The TCP layer provides an application-
A network protocol is a collection of standards, rules, and norms that a computer uses to Exchange data over a network. Common protocols are TCP protocol, IP Protocol, UDP protocol, ICMP protocol. These are all transport protocols, as well as application layer protocols such

Network is a tool that everyone can't do without. It is becoming more and more active. How much do you know about these computer network protocols? Understanding the use of these protocols can help us use computer networks more rationally. Now, we will introduce several commonly used computer

Network communication protocols, as the name suggests, are the protocols used for communication in computer networks and the standards for various network data transmission and other work, only one effective standard model can ensure that all kinds of services and services on the Internet can be completed in an orderly
6.4 Configuring network ProtocolsThe database engine must have network protocols enabled before the client connects to the database engine. The SQL Server database engine can simultaneously enable multiple network protocols for the request service, and the client uses a sing

In the CAN network, data transmission and receiving of all nodes share a bus. In the face of an unknown multi-node CAN bus network, how CAN we accurately analyze the communication protocols
The data link layer has three main purposes:
* Sends and accepts IP data packets for the IP module;
* Send ARP requests to the ARP module and receive ARP responses;
* Send RARP requests and RARP responses to RARP.
The ARP protocol is mainly used to resolve the 32bit IP address to the MAC address (hardware address) corresponding to the 48bit (Ethernet ). The RARP protocol resolves the hardware address to an IP address. The two protocols are at the
Network protocols play an important role in movie servers. It can be said that without network protocols, movie servers will not be able to play a normal role. This article briefly introduces several mainstream network protocols,
Every time you write and design a network communication program, you always have to deal with the problem of customizing a set of application protocols (that is, communication protocols) and then writing corresponding methods to parse the protocols, and provides corresponding interfaces for upper-layer calls. It is eas
-scale network environments. The RIP protocol is used to transmit route information in an AS autonomous system. Route information is updated every 30 seconds. The RIP Protocol provides hop count to measure the route distance, the hop count is the number of routers required for a packet to reach the target. The maximum number of hops supported by RIP is 15.
Application: in Windows, we can enable the "RIP listener" function to listen to RIP messages, so

SummaryInternet Protocol Security (IPSec) filtering rules can be used to protect Windows 2000-based computers from web-based attacks caused by viruses, worms, and other threats. This article describes how to filter out specific protocol and port combinations for inbound and outbound network communication. This document also includes steps for determining whether an IPSec Policy is specified for a Windows 2000-base

Data is transmitted over the Internet, including media and intermediary equipment. The 7.client receives a data link frame that includes data. Handles each layer of protocol headers, and then removes the protocol headers in the reverse order of accession. First, the Ethernet information is processed and removed. The IP protocol information is followed. The next
I have read more than just some introductory articles. At least I have downloaded the standard protocol document and read more than the overview part :)
Some protocols have participated in the development of commercial products;
Some are just some of the implementations of open source code;
Some, just look at it and understand the design ideas of the Protocol.

The driving force of technological development is the constant demand of people. With the increasing use of the Internet, the current network protocol version is no longer able to meet the needs of the times. Inevitably, we will launch a new generation of IPv6 network protocols that are more complete and have diverse functions. The inevitable elimination of IPv4
We all know that computer networks are divided into seven layers, each of which has its own network communication protocol. We can easily understand the concept of network communication protocol. However, it contains many protocols. Here we will summarize several important protocols to help you make a summary. See the
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 relatively easy to understand introduction:"When we transmit data, we can only use the (Transport Layer) TCP/IP protocol, but in that case,
the address type to be converted, and 0x0800 is the IP address, the length of the following two addresses is 6 and 4 (bytes) for the ethernet address and IP address respectively. The op field is 1, indicating the ARP request, and the OP field is 2, indicating the ARP response.
The process of the Address Resolution Protocol is as follows:

The opposite of ARP is mainly used to obtain the IP address of a diskless workstation, as shown in.
