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

I. Token Bus ARCNET is a local area network developed by datapoint in 1977. It is still widely used,And uses RG-62 coaxial cable as the NetWare LAN cabling system. ARCNET, which is exactly the same as ibm3270The cables connecting the terminal and the IBM host are the same, so this network is widely used in the Use base of a large number of IBM hosts.ARCNET can now use twisted pair wires and optical fiber cables. The new arcnet plus Speed has increased from 2.5 MB/STo 100 Mb/s (when using optical

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

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

Ethernet switches are still commonly used. So I studied Ethernet switches and their devices. I would like to share them with you here. I hope they will be useful to you. Ethernet is the most widely used in L2 switches ). At present, more than 90% of local area networks around the world use Ethernet technology. With the

Ethernet is the most widely used in L2 switches ). At present, more than 90% of local area networks around the world use Ethernet technology. With the development of Ethernet technology, this technology has entered the access network and man fields. In this article, the author puts forward a new idea of virtual circuits in the

The following are various packages: Ethernet II encapsulation: Ethernet technology is based on Ethernet frames, also known as standard Ethernet frames (ARPA), that is, Ethernet II frames (originally known as DIX, the initials of the three launch companies Intel and Xerox

In the early 1990s s, with the improvement of computer performance and the increase of communication traffic, traditional local area networks have already surpassed their own load, and the emergence of switched Ethernet Technology, this significantly improves LAN performance. Compared with the current LAN topology based on bridges and routers, network switches can significantly increase bandwidth, while the addition of exchange technology can create a

Ethernet switches are expanding their applications to the network core. This is mainly from two aspects: one is that Ethernet switches have the function of routers, not even, there are more than three layers of switches; the second is the maturity of the physical layer technology and the Exchange technology makes the Ethernet break through the area of the LAN, an

Because Fiber Ethernet has the WAN function, it is bound to promote the sale of LAN Fiber Ethernet devices to operators. Here we analyze how Fiber Ethernet breaks through its Development limitations. The Optical Fiber Ethernet product can use Ethernet devices to implement WA

The Gigabit Ethernet technology is gradually being upgraded. In addition to its original compatibility, broadband, low cost, and good support for IP addresses, it also features reliability and scalability, there are also many price issues that people are most concerned about, all having a qualitative leap. Currently, Radio and Television Broadband man hosts IP-based services. The platforms that carry IP addresses mainly include four technologies: ATM,

IntroductionEthernet is the most successful LAN (local area Networking) technology in the last 30 years. 1. First widely used LAN technology (a widely used LAN technology) 2. Kept up and speed race:10 mbps–100 Gbps 3. connectionless: No handshaking between sending and receiving NICs (network Interface card, network card) No connection is established. 4. unreliable: receiving NIC doesn ' t send ACKs or nacks to sending NIC Not reliable. Ack:acknowledgement, that is, the confirmation character, in

Carrier Broadband Technology One of the success of Ethernet is the infiltration in the field of telecommunications, not only the telecom operators for the needs of users to adapt to the needs of Ethernet transmission technology, while the telecommunications operators in the network using Ethernet technology. (Computer science)

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 switches are still commonly used. So I studied the Ethernet switch access solution and shared it with you here. I hope it will be useful to you. Fiber-optic Ethernet technology is the integration and development of the two mainstream communication technologies, namely, Ethernet and optical network. It integrat
