What are the characteristics of Ethernet?

It reduces a lot of unnecessary expenses, simplifies the SDH frame structure, enhances the network management and maintenance of the physical layer compared with Gigabit Ethernet, and can realize protection switching on physical lines.

1 and Gigabit Ethernet technology, as the latest high-speed Ethernet technologies, bring users effective solutions to improve the core network. The biggest advantage of this solution is that it inherits the advantage of low price of traditional Ethernet technology.

2. Upgrading to Gigabit Ethernet does not need to change network applications, network management components and network operating systems, which can protect investment to the greatest extent.

3. Fast Ethernet technology can effectively ensure users' investment in cabling infrastructure. Support the connection of 3, 4 and 5 twisted pairs and optical fibers, which can effectively use the existing facilities.

Extended data:

1, Ethernet is a computer local area network technology. The IEEE 802.3 standard of IEEE organization sets the technical standard of Ethernet, which includes physical layer wiring, electronic signal and medium access layer protocol.

2. Ethernet is the most widely used LAN technology at present, which has replaced other LAN technologies such as Token Ring, FDDI and ARCNET.

3. Start-If the line is idle, start transmission, otherwise skip to step 4. Transmit-If a collision is detected, continue to transmit data until the minimum echo reception interval is reached to ensure that all other repeaters and terminals detect the collision, and then skip to step 4.

4. Successful transmission-Report the transmission success to the higher layer network protocol and exit the transmission mode. Busy-Wait until the line is free. Line idle-Go to step 1 at random intervals before reaching the maximum number of attempts, and then try again. Maximum transmission attempts exceeded-Report transmission failure to higher layer network protocol and exit transmission mode.
