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

In actual use, an Ethernet switch generally does not require both parties to send and receive data at the same time. One-way transmission devices such as printers can be used in half-duplex or even single-ticket mode, and do not need to switch back, one-way transmission devices such as printers can be used in half-duplex mode or even in a single ticket, and do not need to be reversed. In actual use, it is generally not necessary for both parties to se

The emergence of 10-ge switches completely realizes the convergence of private networks to the public network, and it can provide a throughput of more than one thousand G in one second, which is not supported by traditional switches. As compatible with the latest Ethernet technology, 10-Gigabit Ethernet is not only a "high-speed rebuild" of Ethernet. For the firs

In actual use, an Ethernet switch generally does not require both parties to send and receive data at the same time. One-way transmission devices such as printers can be used in half-duplex or even single-ticket mode, and do not need to switch back, one-way transmission devices such as printers can be used in half-duplex mode or even in a single ticket, and do not need to be reversed.

There are many things worth learning about switched Ethernet. Here we mainly introduce the working principle and advantages of switched Ethernet. 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 d

Memorandum status This RFC describes a standard method for encapsulating IP data packets over Ethernet. This RFC is provided for the ARPA-INTERNET community. Introduction This memorandum is applicable to Ethernet (10 Mbps, 48bit address ). Describes the transmission process of IP data packets over the investigational Ethernet (experimental

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

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

With the continuous development of China's equipment manufacturing industry, increasing competition and international market demand, various manufacturers are accelerating equipment upgrades and upgrades. How to improve and upgrade equipment at the lowest cost in the shortest time has become an important problem for manufacturers. The Industrial Ethernet switch adopts the storage conversion and switching mode to improve the

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

Because of the actual use of the requirements we test the network communication, on the NUCLEO-F412ZG Test board does not have an Ethernet section, we choose to add a W5500 experimental board. W5500 supports SPI interface communication, dc3.3v feed. And the NUCLEO-F412ZG Test board has SPI1 each pin Spi1_nss (cn7_17), Spi1_sck (cn7_10), Spi1_miso (Cn7_12), Spi1_mosi (cn7_14) to the CN7, The 3.3VDC and GND also guide the CN8, which can be easily implem

1. Introduction The IEEE 802.3z Gigabit Ethernet Standard, adopted in June 1998, describes 3 physical layer interfaces (1000BASE-SX, 1000BASE-LX, and 1000BASE-CX) that are used for a universal link encoding and can be 1000mb/s transmitted. 1000BASE-SX, 1000BASE-LX interface using optical fiber as a medium, the farthest transmission distance of up to 5000 meters, so can be used in buildings or campus backbone network. The 1000BASE-CX interface is plan
