The network Protocol is a special software and the most basic mechanism for a computer network to implement its functions. Network protocols are essentially rules that must be followed by a variety of hardware and software. Network protocols are not

Q: What is the difference between RIP, IGRP, and iversions? A: There are different types of routing protocols. The main difference between RIP and IGRP is the distance vector protocol, while that between RIP and IGRP is the connection status

I. Preface I used protocol analysis tools for learning.TCP/IPHereinafter referred to"Learning"), See"Hope to provide other supplements again"You have always considered what to add, and there are a lot of things to add. After allTCP/TPProtocol

1 Introduction Inter-board communication bus is one of the key technologies that determine the stability and reliability of SDH system equipment. The physical layer channels of Inter-board communication cannot be error-free. You must select an

SCO TCP/IP network management-Trust RelationshipWe have discussed the FTP configuration above. It is also an important service in network management. Let's talk about it below.Another important concept of network management is the trust relationship.

Table 5. IP packages from A to B In this case, IP addresses are redundant because they do not play any role at all. IP addresses can only increase the processing time and occupy excessive transmission bandwidth. After B receives the package,

In a LAN, you must specify an IP address, which is the unique identifier of each computer. In a small LAN, this work can be set manually, but for a large LAN, manual setting is troublesome and error-prone.So we can use the DHCP function in Win2000

I recently called an ATM-Frame Relay Network and used OSPF in the middle to create a domain. I thought it was very EASY, but the route was always unavailable. SH IP OSPF NEI, it is found that NEI cannot be FULL. Check the configuration. If DEBUG is

Background:When an intranet accesses the internet, it may have physical connections with 50000 unknown networks and users. By enabling these connections, you can use various applications and shared information, although most of the content cannot be

As early as the advent of the web, the Internet was growing at an astonishing speed, and its development was faster than everyone expected. 10 years ago, people began to focus on the expansion performance of the Internet in the future. They worried

OSPF routing protocol is often used in large networks. For example, the municipal unit center 7513 is used as the core device. The OSPF protocol is used in connection with the Provincial Unit at the upper level, subordinate county-level units

Next, I will explain the NAT penetration problem caused by the SIP protocol and propose solutions.1. There are roughly four types of NAT.A) Full ConeB) restricted cone of restricted coneC) restricted cone of port restricted portD) symmetric ricA, B,

Wireless Networks have developed at a faster speed, but we cannot deny that many users do not know it very well and cannot grasp the key points of the purchase, so today, I will share with you the key points for purchasing wireless products, hoping

There are many things worth learning about the Broadband Access Server. Here we mainly introduce the forwarding Management of IP traffic in the broadband access server. The broadband access server is positioned at the edge of the backbone network.

The optical fiber access technology is worth learning a lot. Here we mainly introduce the Networking Solution of the optical fiber access technology. With the development of the Internet cafe industry, the competition is becoming more and more

There are many things worth learning about in broadband access networks. Here we mainly analyze when IP Broadband Access networks will enter a new era. The so-called scalability refers to the ability to serve millions of users within a wide area

It is very complicated to understand the differences between ADSL and MODEM from the basic concepts. For many people, it is confusing to understand the interconnection between companies or the company's large network connections, despite this, many

Currently, radio and television data networks are mainly constructed over Ethernet. As operators, apart from establishing a stable and reliable network, it is also important to select a good broadband access method. A good access method not only

In view of the uneven quality of practitioners in the field of structured integrated cabling in China, there are deviations in the understanding of testing methods and testing standards, this newspaper will give a brief introduction to the

In the field of cabling, we often see terms related to cabling media, such as Category 5, Category 5, Category 6, Category 6, and category 7. How should we choose between advantages and disadvantages?These terms represent the different evolution
