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 LAN with broadcast channel (down)--------- frame format (MAC)L Hardware address (Mac address ) of the MAC layerIn a local area network, the hardware address is also called the physical address, or the MAC address. ( address of the location)The "address" as stated by the 802 standard should be strictly the "name" or identifier of each station. In fact, our textbook address is not very accurate, but we are accustomed to this type of "name" is
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)
1. Frame InjectionFor an introduction to Ethernet frames and raw sockets, refer to a previous post that uses raw sockets for Ethernet frame sniffing. Features of frame injection: Packets from the original data format can be injected into the network. Very powerful in analog network response. The original socket package structure is not malleable. Random Injection If you can ra
WIZ550S2E is a gateway module that provides RS-232 to TCP/IP protocol functionality. And can be based on TCP/IP and Ethernet network equipment management, remote measurement, simply use the RS-232 serial port to connect the current device. In other words, WIZ550S2E is a protocol converter that sends data through the serial port in TCP/IP data format, and vice versa.Characteristics Plug and Play serial to
For users who use Apple's Mac system, after a recent upgrade to the system patch, there is a problem with the failure of the Ethernet interface on the IMAC and MacBook Pro, which causes the user to connect to the network via WiFi only, and not directly through the Ethernet interface network. What is the cause of this problem? What should we do about it? Follow the small series together to understand the sol
Absrtact: Spanning tree algorithms and protocols are the basis for automatically generating network topologies. This paper expounds the content of spanning tree algorithm and protocol, and gives the realization process in Ethernet switch. It is proved by practice that the square tip has a good effect on the analytic optimal topological structure of the network. The Ethernet switch must have routing capabil
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
From 10M, 100M, gigabit to Gigabit Ethernet, the development of Ethernet technology, in the rate of increase in the number of levels, the application of the field is also widening. However, the application requirements of different application fields have promoted the individualized development of Ethernet technology in these fields. At the same time,
Soldier Ethernet Tester is a test instrument based on PC Card. So how does a soldier Ethernet tester work? The main interface of the software is as follows: OK, let's take a look at each function point of the software together. A new or edited message In the list box on the right side of the software main interface, click the right button, according to the menu prompts, you can make a new me
Translated from: http://ricardo-dias.com/2010/11/20/arduino-wakes-my-pc/I've always dreamed of controlling something in my room through the Internet. Watch IPTV on the computer, turn on/off the lights, remote control peer download ... To do this, I need a server – my old desktop can do it. Of course, I didn't mean to hang it all day/week/month ... ^^I need to find a way to revive it whenever I want to. So I think I can use an Arduino and Ethernet boar
--Transmission Protocol/Network Protocol) is an industrial standard protocol set, including IP, TCP, UDP and other protocols to ensure the correct transmission of data on the network. TCP/IP protocol is the foundation of modern Internet. The TCP/IP protocol is a four-layer model: Application layer, Transport layer, network layer and data link layer. Each layer has a different function, and the layers and layers are logically independent of each other. Each layer corresponds to a number of sub
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
Metro Ethernet is still commonly used. So I have studied the case study on environmental optimization of Metro Ethernet. Here I will share it with you and hope it will be useful to you. Before implementing this optimization scheme, the access layer switches in the current network come to three aggregation layer Ethernet switches Aggregate-1, Aggregate-2 and Aggre
