network protocol testing

A major feature of AdHoc wireless networks is that they require a large number of routing protocols. General wired routes must be transformed to adapt to AdHoc wireless networks. We will discuss in detail some types of AdHoc wireless network routing protocols. Through these analyses, I hope you can understand this. AdHoc wireless network routing protocol analysis

Abstract: With the development of computer networks, it brings resources sharing to people. At the same time, there are great security risks in data security. The TCP/IP protocol is widely used for communication in today's networks. This article analyzes computer network security issues based on TCP/IP communication protocols and explores corresponding network se

1. Linux Network Path 1.1 Sending End 1.1.1 Application Layer (1) Socket The application layer of the various network applications are basically through the Linux Socket programming interface and kernel Space network protocol stack communication. Linux sockets are developed from BSD sockets, one of the most important

With the development of China's routing industry, it also promotes the continuous improvement of dynamic routing protocols. Here we mainly introduce the dynamic routing protocol used in network communication, computer networks) it is a complex system with many technologies, and each technology plays an irreplaceable role like other technologies. Many international organizations and companies have set

In Passive Optical Network (PON), the difficulty of Installing Optical Fiber Links and passive devices must be re-examined by the current standard testing technology. One of the other challenges encountered by the testing technology is that the 1490nm wavelength brings special difficulties to the OTDR. When the splitter is installed for

OSI is an open reference model for System Interconnection. It is a well-defined protocol specification. The OSI model has a layer-7 structure, and each layer can have several child layers. Next I will briefly introduce these 7 layers and their functions. Layer 7 of OSI is 7 Application Layer 6 presentation layer 5 Session Layer 4 Transport Layer 3 network layer 2. Data Link Layer 1 Physical Layer Among them

The 23rd Chapter Rl-tcpnet Address Resolution Protocol ARPThis section for everyone to explain the ARP (address Resolution Protocol, addresses resolution Protocol), through the previous chapters on TCP and UDP learning, you need to have a basic understanding of ARP.(The knowledge points in this chapter are mainly organized from the

Network Protocol Reading Notes Overview 1. Why are TCP/IP protocols required? 1) different computer hardware runs different operating systems. 2) different LAN hardware: Ethernet, Token network, etc. 3) information exchange. The TCP/IP protocol forms a wide area network comp

For some protocol analysis, we can use the power of some software. Here we will explain the WinPCap and computer network protocols. Let's take a look at the working principle of WinPCap: System Development and Application WinPcap supports information packet capture and network analysis on the Win32 platform. Its main idea is derived from the most famous packet In

Internet ProtocolI. OverviewThere are different models for layering, some models are divided into seven layers, and some are divided into four layers. Here is the introduction of the Internet into five layers.The bottom layer is called the "Physical layer" (physical layer), the topmost layer is called the "Application Layer" (Application layer), the middle layer three (bottom-up) is the "link layer", "Network layer" Layer), and the transport layers (T

Workflow and status of PPP protocol 1. Workflow of PPP protocolWhen a user dials into the ISP, a physical connection is established from the user's PC to the ISP. Then the user PC sends a series of LCP packets to the ISP (encapsulated in multiple PPP frames) to establish the LCP connection. These groupings and their responses select some of the PPP parameters that will be used. Then there is the network la

I. Overview Review the video surveillance market, the monitoring platform system used by the signaling control protocol is not unified, resulting in the interconnection of the technical threshold. This is a bit similar to the 80 's China's switch market eight system of the situation. These reasons hinder the network era of large-scale carrier-level video surveillance, remote access, centralized management n

The idea of the Nagle algorithm is good. It avoids small packets in the network and improves the network utilization. But when NagleAlgorithmThe tragedy of delayed ack happened. The intention of delayed Ack is to improve TCP performance. It should bring ack to the response data, and avoid confusion window syndrome. It can also identify multiple segments with one ack to save costs. The tragedy occurs in th

For network security, the accuracy of NTP is crucial. Setting it correctly takes only a small amount of time to protect its security without any extra investment, but the security improvements will be very large. This article describes in detail how to set the network time. Network Time Protocol (NTP) is a dedicated
