Secret: 58 essential knowledge points of switched Ethernet. you can master the following knowledge points of switched Ethernet in just a few minutes. Welcome to the vswitch world. The local connection will also be mentioned in this article. ◆ Ethernet was originally based on coaxial cable. In, Xerox \ inter and DEC proposed DIX. ◆ In, the standard was proposed. ◆

When the Ethernet device receives the packet, it first saves it to the buffer zone and then forwards it out. An Ethernet device is like a cargo transfer station, and a packet is like a packed cargo. How does cargo transfer station work? Assume that the transfer station has four doors, each of which can be used as the entrance and exit. The purchase speed and delivery speed of all ports are the same. In the

We are very interested in the explanation of the remote network monitoring proxy for the Gigabit Ethernet switch RMON proxy. Before giving you a detailed description of how to use remote network monitoring proxy, let's first understand the basic knowledge of RMON and then compare the advantages and disadvantages of the following methods. Remote network monitoring RMON) is the most important enhancement to SNMP. This article introduces the implementati

Scenario 1–simple VNet with Active/standby uplinks–ethernet and fcoe–windowsScenario 1: Simple vnet using Active/standby uplinks-ethernet and FCOE-WINDOWS2008R2Overview:This simple configuration scenario uses VC vnet and FCoE to meet SAN requirements. This simple design does not use VLAN mapping,vnet is the simplest way to connect virtual connect to network and server components. In this scenario, the uplin

We all know that the higher the bandwidth of an Ethernet switch, the stronger the data processing capability, but the disadvantage is that the cost will rise, the switch type is rack-mounted, fixed configuration with/without expansion slot) A rack-mounted switch is a slot type switch that provides excellent scalability and supports different network types, such as Ethernet, fast

Ethernet switch technology development trend in recent years, with the rapid development of enterprise data communication services and related fusion services, Ethernet switches, as an indispensable key equipment, have not only greatly increased the number, in addition, it is constantly improved in terms of quality and performance. Enterprise information applications are moving towards broadband and converg

different port that is forwarded to that port and terminated on that port. Up MEP and down MEP also have other names in different places, such as outgoing and inward MEP: is up MEP, sending a paper to relay entity, also called an introverted MEP. Is the down MEP, which sends the PDU to the network direction--------------------------------------------------------------------------------------------------------------- -------Ethernet (

Ethernet switches are still commonly used. So I have studied the concept and principle of the data network Ethernet switch. I will share it with you here, hoping it will be useful to you. Switching) refers to the technology collectively used to send the information to be transmitted to the corresponding route that meets the requirements according to the needs of transmitting information at both ends of the

CCNA Study Notes 2 --- EthernetEthernet ◆ type: 1, EthernetII; 2, 100 standard Ethernet (10 Mbps) Fast Ethernet (1000 Mbps 10 Gbps 40 Gbps, using CSMA/CD access control, all are in line with 802.3 ◆ L2 network Classification 1, point-to-point: WAN network serial port 2, multi-point} ---- Ethernet broadcast} ---- Frame Relay does not support broadcast ◆ collision

Q: How to implement a single chipEthernetMicrocontroller?A: The trick is to connect the microcontroller and Ethernet Media to the Controller (MacAnd physical interface transceiver (Phy) Integrated into the same chip, which can remove many external components. This solution enables good matching between MAC and PHY, and reduces the number of pins and chip area. The Single-Chip Ethernet microcontroller also r

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

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.

Java| block chain development and communication group: 613121183 Interested can also add ha, provided a lot of block chain information, there will be data can be met to share ----------------------------- Lihe August 28, 2016 Many people are puzzled by the block chain and the ether square, Do not know how to learn, this article simply said some of the learning methods and resources.I. The relationship between the ether Square and the block chain From the history of the Block chain, the first bir

These things will not be confused, because they are not a level of East, now think about the early I feel some do not understand because the agreement is in the abstraction layer is not clear, the knowledge should be from the bottom solid walk.First, the agreement is not big, the agreement is the two sides agreed to abide by the norms, only that. The data transmission between the Internet is on the Ethernet, and it needs to do some processing before i

Generally, the Integrated Wiring System is updated every seven years. It takes five years to replace the three-category system with the Five-category system. It takes only three years, cat6 systems are mature and increasingly widely used. It is a trend to implement Gigabit Ethernet in cat6 systems, and standards for cat6 systems are being formulated and initially implemented, bringing copper cabling systems to the fullest is the latest goal of 10 Giga
