network protocol testing

This article describes the IP protocol required to understand routing issues. Most things on the internet use the IP protocol. Different from Ethernet, understanding this protocol is very important for understanding network applications in a wider range. In a later article, this lecture will introduce TCP and UDP proto

HTTP1.1, the HTTP1.0 has been further improved, in addition to a number of request methods, the biggest improvement is to keep the HTTP connection status. This is useful for applications that frequently transmit data. Since the HTTP protocol has reached its goal, the HTTP1.1, which is responsible for making the specification, has stopped improving HTTP (and HTTP-related protocols or extensions have not stopped), so the final version of the HTTP

TCP is used everywhere. Understanding the working principles of TCP helps administrators correctly diagnose network communication faults.The TCP protocol is complex. But don't worry. We didn't ask you to read RFC 793. This is just an initial lecture. In this lecture, we will only introduce the knowledge required for the next lecture on TCP protocol. After learnin

. Listener principles Ethernet, a popular LAN technology invented by Xerox, contains a cable from which all computers are connected, each computer needs a hardware called an interface board to connect to Ethernet. The protocol works by sending packets to all connected hosts. The packet header contains the correct address of the host that should receive data packets, because only the host with the same destination address in the data packet can recei

interference, geography, environment, and other factors. From the above features, we can know that a complete wireless mesh network protocol must have the following features: Distributed operations Fast Convergence (to ensure faster movement) Scalability Suitable for a large number of small devices Use only limited bandwidth and computing power Proactive operations (Reducing Initial latency) When selecting

Layer Seven Protocol: Physical Layer :The computer is connected by a network cable/radio wave, while the physical device only transmits electrical signals (high (1) low (0) levels!Example://010101010000111010101010101010 (data that needs to be passed) Data Link layer :Pure 0 and 1 have no practical significance! 0 and 1 must be grouped and interpreted in a defined way!Ethernet

When I got to work early in the morning, my colleague Zhang rushed to my office and said that all the four computers they bought yesterday had problems, this may be my recommended gb cpu and MB memory brand machine. How can this problem be solved. What are the questions? He said that neither the network nor the LAN could be connected. Alas, this was the case, and I was relieved. The problem must be that no communication

We can use the network protocol analyzer to observe the network protocol analysis. Here we will explain the network analyzer. The best way to analyze data packets transmitted over the network depends largely on the device you have

When network frames enter the network layer, it is necessary to distinguish between different network protocols for processing, which involves protocol processing functions.First we receive a data frame from the driver and analyze the data frame's bottom-up transmission flow in the

called "Network Control Block. The allocation of these blocks in the memory depends on the user program. These "network control blocks" are allocated to the domain and reserved for input and output respectively. In today's environments, NetBIOS is a common protocol. Ethernet, licensing ring, and ibm pc network suppor

The tcp ip protocol is the basic transmission control protocol that must be used during network construction. How can we conduct modulation and analysis in this aspect during the networking process? First, we need to know some important protocols in the tcp ip protocol and other protocols to be used in the

Welcome back to the core of the Network: routing protocol. In this series of route protocol lectures, we will first introduce one of the earliest and simplest protocols: the route information protocol (RIP ). Like all protocols, RIP is used to distribute network information

When we talk, we should conform to the rules of grammar and terminology. Calls between machines must also meet the protocol. Otherwise, 're same page, can not understand each other. "Protocol Forest" is a series of articles on

The NetBEUI protocol has many advantages, but its most prominent disadvantage is that it does not support the routing function, which is also one of the reasons for its gradual development. However, some small networks, especially local networks, still need this protocol. So here we will introduce this agreement in detail. NetBEUI is the NetBios Enhanced User Interface, or the NetBios Enhanced User Interfac

A good understanding of how TCP and UDP works is essential for any programmer. That's why the difference between TCP and UDP is a popular Ja

Deploying a video chat system: testing network quality and deploying a video chat system For a real-time network voice and video system, the quality of the network plays a decisive role in the user experience of the system. Therefore, before the system is officially deployed, it is necessary to conduct comprehensive

You may have heard of the TCP/IP protocol. Do you know what TCP is and what Ip is? In this chapter, we will learn about the most widely used protocol on the network. 7.1 network transmission layeringIf you have passed the computer grade examination, you should have understood the concept of
