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
main driving force of Wan Xiaotong Cable Ethernet is to reduce the cost of Ethernet network, for a wide range of implementation of Gigabit Ethernet, the use of optical fiber transmission solution has been proved to be too expensive, so based on the copper cable solutions ca
Ethernet is the undisputed overlord of the Internet world. It has been firmly occupying the territory of commercial office environments in recent years. The field of control and automation is also moving towards this open, standards-based technology. Do you think the cables used at the reception desk can also meet the demanding requirements of industrial process control and automation technology environments? In fact, COTS (Popular) 5e unshielded twis
Have you ever had a working environment that is against your experience? But if you're in the same boat as a cable, you might be able to cause data transfer errors or network delays, or you might be able to damage the entire cable if you drive on the cable. For this, ordinary commercial cables are not even immune to the possibility.
In fact, the popular commerci
Fluke Networks (Fluke Network) has launched an ethernet cable tester "DTX-1800", in addition to the widely used "5e" line, it can also be used to detect "6" and "7" lines with better transmission characteristics. You can check whether the cables used as the measurement object meet the corresponding specifications. The testing frequency is up to 900 MHz. Reduce the testing time of the "6" line to 12 seconds,

Bandwidth acceleration is a significant feature of the rapid development of modern information society. From the operator's perspective, the demand for Household broadband acceleration, the emergence of IPTV operations, the construction of 2G/3G and LTE base stations and core networks, the expansion of business outlets and OSS systems, all of them propose IP
It is not a specific network, but a technical specification.
Ethernet is the most common communication protocol standard used by local area networks. This standard defines the cable type and signal processing method used in LAN. Ethernet is 10 ~ 10 Base T Ethernet is the most widely used
Flash (0x0 ~ 0 xfff), which can be used for loading applications and for "application programming" (IAP) of user programs, that is, remote firmware upgrade, it can be configured through bl_config.h as a remote upgrade communication mode through serial port, IIC, SSI, Ethernet and USB. In the ser2enet folder, the main code for serial port to Ethernet is stored from 0x1000 of flash.

SetRERPAs a large-scale ring Ethernet deployment technology, Ethernet network protection solves problems such as weak protection capability of traditional data networks and long fault recovery time, it is an important technical choice and solution for carrier man construction.

When the number of ports that a single switch can provide is insufficient to meet the requirements of the network computer, more than two switches must provide the corresponding number of ports, which also involves the connection between switches. Basically, there are two ways to connect vswitches: Stack and cascade.
