[TCP/IP] Computer network performance indicators
Network performance indicators are indicators for measuring network performance, mainly including rate, bandwidth, throughput, delay, and bandwidth-delay product.
Rate: The rate at which a host connected to a computer network transmits data bits on a digital channel. The unit is b/s kb/s mb/s gb/s
Bandwidth: The digital channel The highest data rate that can be transmitted. Check that my network card is 144Mbps
Throughput: the amount of data passing through a certain network per unit time
Latency: send delay, transmission delay, processing delay, queuing delay
Send Delay = data block length (bits)/bandwidth (bits/second)
The delay bandwidth product represents how much data is on the way
RTT round trip time
Use ping test, ping the gateway first, Then ping Baidu and Google dns

The full name of tcp/ip is "Transmission Control Protocol/Internet Protocol", which means "Transmission Control Protocol/Internet Protocol" in Chinese. The TCP/IP protocol not only refers to the two protocols TCP and IP, but also refers to a protocol cluster composed of FTP, SMTP, TCP, UDP, IP and other protocols, just because in the TCP/IP protocol, the TCP protocol and the IP protocol The most representative, so it is called TCP/IP protocol.

How to use PHP and TCP/IP protocol for data communication Introduction: In the modern Internet era, data communication is a very important aspect. Whether it is communication between a client and a server or communication between different servers, the TCP/IP protocol has always been one of the most commonly used communication protocols. This article will introduce how to use PHP language and TCP/IP protocol for data communication, and provide relevant code examples. 1. Introduction to TCP/IP protocol TCP/IP protocol is the basis of the Internet protocol cluster. It defines

Differences: 1. TCP/IP is a protocol cluster, while OSI is a model; 2. TCP/IP is a five-layer structure, while OSI is a seven-layer structure; 3. The third layer of TCP/IP only supports the IP protocol, and OSI Supports all network layer protocols. Connection: 1. OSI introduces the concepts of services, interfaces, protocols, and layers, while TCP/IP draws on the concepts of OSI; 2. OSI has models first, then protocols, standards first, and then practices, while TCP/IP IP first has protocols and applications and then proposes a model, which is the reference OSI model.

Application layer protocols include: 1. Telnet, which allows users on one machine to log in to a remote machine and perform work; 2. FTP, which provides a method to move files from one machine to another; 3. SMTP is a protocol that provides email transmission; 4. SNMP is a standard protocol used to manage network nodes in IP networks; 5. DNS is mainly used to "translate" familiar web addresses into An IP address that a computer can understand; 6. HTTP is a request-response protocol used to obtain the home page on the WWW.

TCP and IP are two different protocols in the Internet: 1. TCP is a transport layer protocol, while IP is a network layer protocol; 2. TCP provides functions such as segmentation, sorting, confirmation and retransmission of data packets. , and the IP protocol is responsible for providing source and destination addresses for data packets; 3. TCP is a connection-oriented protocol, while the IP protocol is connectionless; 4. TCP also provides flow control and congestion control.

The Go language is a growing programming language that is designed to be ideal for implementing network applications with high performance, reliability, and concurrency. When using Go to write network programs related to the TCP/IP protocol, we are prone to encounter various errors, and some common TCP/IP errors will also bring certain difficulties to the debugging of the program. This article will focus on the topic of how to solve common TCP/IP errors in the Go language. 1. EOF error EOF (EndOfFile) error usually

IP belongs to the "network layer" protocol of computer network architecture. IP refers to the Internet Interconnection Protocol, which is a network layer protocol in the TCP/IP system. It can provide information of various protocols to the transport layer, such as TCP, UDP, etc.; IP information packets can be placed in the link layer through Various technologies such as Ethernet and Token Ring network are used for transmission.

The "TCP/IP" protocol is the most basic protocol on the Internet. TCP/IP (Transmission Control Protocol/Internet Protocol) is a network communication protocol that standardizes all communication devices on the network, especially the format and transmission method of data exchange between one host and another host; TCP/IP protocol It is the core and most basic protocol of the Internet. Strictly speaking, it is a four-layer architecture, including the application layer, transport layer, network layer and data link layer.
