Http://blog.csdn.net/sailor_8318/article/details/3907345 Differences between switched Ethernet and shared Ethernet A hub, also known as a hub, belongs to the data link layer in the OSI model. However, as the hub is a shared-bandwidth device, the efficiency of the hub becomes very low in the heavy network and is prone to broadcast storms. Therefore, we cannot see hubs in medium and large networks. A vswi

IEEE has just approved the Ethernet P802.3az Energy Sensing standard, which reduces the energy consumption of networked devices while they are running. Reducing energy consumption is the next goal of information and communication technology managers in order to spend less money and work more, energy-efficient Ethernet can save energy and reduce operating costs. This new standard network, in most cases, au

. Developing energy-saving technology is the key Farber says that, based on the ongoing reality of network congestion, it is clear that in the near future we will need Gigabit Ethernet. Farber believes that Gigabit Ethernet not only meets the needs of the data transmission speed and bandwidth of the Internet, but also high performance, high speed Ethernet can c

I Current Status and Development of Industrial Ethernet Technology The so-called industrial Ethernet is technically compatible with commercial Ethernet (that is, the 802.3 standard), but in product design, it can meet the needs of industrial sites in terms of material selection, product strength, applicability and real-time performance.With the development and po

1. Work Summary Recently, the IEEE is working on a new project the project is to develop a standard for the operation of Gigabit Ethernet (10GbE) transmission based on the current copper structured cabling system, which is collaborating with leading experts from integrated wiring, electrical, test equipment and system design, Panduit belong to one of the leading ranks, we have foreseen that with the future increase in transmission rate, cable and conn

Development of Ethernet frame formats 1980 Dec, Intel, and Xerox have developed Ethernet I standards1982 Dec, Intel, and Xerox have developed standards for ew.net II1982 IEEE started to study the International

The main network elements in the Ethernet network include switches, routers, firewalls, servers, and clients. By testing the Ethernet network elements and the network itself, the network structure can be optimized, the network fault is eliminated and the network performance is mastered. Ethernet testing is also rule-based, such as the well-known rfc2544/rfc1242,

Whether from the demand side or from the supply side, the overall network is moving towards broadband, which gives Ethernet a good space for development. From a technical point of view, over the past 20 years, Ethernet bandwidth from 10 trillion, hundred trillion, gigabit, has been developed to 2002 million trillion, or even 40,000 trillion, 100,000 trillion are already in the research and discussion stage,

Ethernet (EtherNet)Originally created by Xerox, the Ethernet was developed jointly by DEC, Intel and Xerox three companies in 1980 as a standard. Ethernet is the most widely used local area network, including standard Ethernet (10Mbps), Fast

-100mbps Ethernet access to the door system has become a new trend of broadband access network.The current broadband IP network access network is basically based on broadcast technology Ethernet, the media Storage Control (MAC) protocol is the collision detection/carrier interception multi-channel Access Protocol (CSMA/CD). The basic principle of CSMA/CD is that each node on the network shares the same tran

With the development of network technology and the popularization of information application, Ethernet switch has been used more and more widely. According to IDC statistics, 2001 domestic switch market value of 6.77 billion yuan, to 48% of the share of the router (46%) ranked in the first place in the network market. Thus, the switch has literally become the most mainstream product in the network market. Three major factors contribute to the rapid g

With the development of network technology and the popularization of information application, Ethernet switch has been used more and more widely. More importantly, it began to penetrate from the simple LAN application to the metropolitan area Network, thus attracting more operators ' eyes. The rapid growth of the switch market, in addition to the overall growth of the network market, mainly benefited from the following aspects. First of all,

Static and Dynamic Ethernet Switching Technology There are many types of Ethernet Switching Technology, each of which has its own advantages. You can use a simple mouse to increase, move, and change the structure of the exchange; network segments are more effective than bridges and routers; high bandwidth is provided for high-performance workstations or servers. Network managers are eager to use these techn

Fiber-optic Ethernet technology is now the integration and development of two major communication technologies, namely Ethernet and optical network. It focuses on the advantages of Ethernet and optical network, such as wide application of Ethernet, low price, flexible networking, simple management, high reliability and

The enterprise network includes all the networks that are not telecom operators, and the enterprise network can be subdivided into LAN, metropolitan area network and WAN. Most of the LAN are used to connect the various nodes, and the network card is Ethernet card, so exactly, optical + Ethernet, will be the next generation of IP metropolitan area Network development trend.By integrating existing urban fibre

The selection of network backbone technology directly influences the performance and future expansion and upgrade of networks system, and should be fully demonstrated and carefully chosen. In the previous years of network construction, many units have chosen ATM as the backbone of the network technology. Gigabit Ethernet is a technology developed in recent years, compared with Fast Ethernet, provides a high
