With the development of the exchange industry in China, we have also promoted the update and upgrade of the Ethernet switch technology. Here we mainly analyze the comprehensive performance of the Ethernet switch. Rack-mounted switch, fixed configuration with/without expansion slot) rack-mounted switch is a slot type switch, which has good scalability and supports different network types, such as

The topological structure of LAN The main features of LAN are: The network is owned by a unit, and the geographical range and the number of sites are limited. LAN has broadcast function, from a site can easily access the entire network, the host on the local area network can share a variety of hardware and software resources connected to the LAN. The local area network can be divided into bus structure, ring type structure, star structure, net structure, tree structure and mixed structure

What are the differences between layer-2 and layer-3 Ethernet switches and their basic types? The following are some comparisons: after reading this article, we will be able to fully understand the layer-3 Ethernet switch. Next we will talk about the three-layer Ethernet switch process. VLAN segmentation is used to isolate inter-VLAN communication, and layer-3

A Fast Ethernet Communication System Platform Based on 12301.6 [Date: 2008-7-22] Source: Today's electronics/21ic Author: Hunan Institute of Technology Yi Jie [Font: large, medium, and small] 　 Introduction With the increasing popularity of Internet applications, the degree of information sharing is constantly increasing. The digitalization and network of embedded devices have become an inevitable trend. Currently, mainstream emb

The use of fiber-optic Ethernet technology can make the fiber access solution more optimized and reasonable. At the same time, many manufacturers have launched their own fiber-optic Ethernet products, and I believe that the market competition will be more intense. Fiber-optic Ethernet technology is the integration and development of the two mainstream communicati

Exchange Technology Development Process Ethernet SWITCH, which is also translated as a SWITCH or a SWITCH-type hub. Let's first review the development process of LAN. The combination of computer technology and communication technology has promoted the rapid development of local computer networks. From the appearance of ALOHA at the end of to the appearance of Mbps switched Ethernet in the middle, in just o

Recently, customers asked to use the MTK 6572 chip via USB OTG add support wired network card, I checked all the hooks and hooks all the site, there is no relevant discussion, see the MTK to the data, including FAQs, only said to support the USB OTG keyboard and mouse and USB stick. What to do? I'm the only one who comes.However, according to my understanding of the USB device mechanism, as long as we hang on the USB Ethernet driver, then the USB

In the previous article we introduced the Ethernet 5 layer model, which I want to learn about the encapsulation and unpacking of Ethernet data, and how Ethernet data is transmitted. First, data encapsulation when our application uses TCP to transmit data, the data is fed into the protocol stack, then passes through each layer one by one, knowing that the final t

Do you know about General Ethernet Access (GEA? General Ethernet access (GEA) is a technology promoted in the UK. However, it may attract American enterprises with branches in the UK or Scotland. As general Ethernet access becomes more and more practical, it is receiving increasing attention in the UK. However, many people are not very clear about the performanc

The development of the exchange technology has become mature. At the same time, driven by telecom operators, the Ethernet exchange technology has been fully applied and its role has become more obvious. With the development of network technology and the popularization of Information Application, Ethernet Switching technology has been widely used. More importantly, it began to penetrate from simple lan appli

There are many things worth learning about Ethernet switches. Here we mainly introduce the new development direction of Ethernet switches. At present, more and more manufacturers are entering the Ethernet market, new brands and new products are emerging, and there seems to be a trend of Homogeneous Competition. However, it is worth mentioning that, as the number

Many people may not quite understand the switched Ethernet technology. First of all, let everyone know from bridges, multi-port bridges to switches, then we will introduce the working principle of the switched Ethernet technology and the advantages of the switched Ethernet technology. Ethernet machine, which is a SWITC

There are many things worth learning about Ethernet switches. Here we mainly introduce Ethernet switch configurations and network types. Rack-mounted switch, fixed configuration with/without expansion slot) rack-mounted switch is a slot type switch, which has good scalability and supports different network types, such as Ethernet, fast

community properties.The Intelligent Community Information system can be divided into two parts of information network subsystem and control network subsystem from function.The Information network subsystem is composed of data system, voice system, CATV system, on the one hand realizes the comprehensive access of data, voice and image, on the other hand provides the transmission channel for the control network subsystem, its transmission way is flexible, can be FTTB +lan, ADSL, HFC, can also be

The internet has grown rapidly with e-mail and www Two free services, prompting rapid growth of Ethernet. Now more and more manufacturers to enter the Ethernet market, new brands and new products continue to emerge, it seems that there has been a trend of homogenization of competition. However, the expansion of the Ethernet switch in the market at the same time,

The history of optical communication with light wave as information carrier is a long-standing one, the atmospheric laser communication is the communication of the atmosphere as the transmission medium, and it is the first kind of communication method developed after the laser appears. Because it has the advantages of long-distance transmission distance, frequency bandwidth, small transmitting antenna, good confidentiality and electromagnetic interference, more and more attentions are paid to it

Why is there a limit to the minimum frame length and maximum frame length in traditional Ethernet?Ethernet (IEEE 802.3) frame format:1, Preamble code: 7 byte 0x55, a string of 1, 0 interval, for signal synchronization2, Frame starting delimiter: 1 bytes 0xd5 (10101011), indicating the beginning of a frame3.
