10-Gigabit Ethernet edit
MAN and WAN capable. User:Itpastorn/dko/Ethernet parameters
- IEEE 802.3 sublayers are mostly preserved (a few additions for 40 km fiber links and interoperability with SONET/SDH technologies)
- TCP/IP can run over LANs, MANs, and WANs with one Layer 2 transport method
802.3ae-family:
- 10GBASE-SR
- short distances
- already-installed multimode fiber
- 26 meters to 82 meters
- 10GBASE-LX4
- Wavelength division multiplexing (WDM)
- 240 m to 300 m over already-installed multimode fiber
- 10 km over single-mode fiber
- 10GBASE-LR and 10GBASE-ER
- Support 10 km and 40 km over single-mode fiber
- 10GBASE-W (10GBASE-SW, 10GBASE-LW, and 10GBASE-EW)
- Intended for use with OC-192 SONET/SDH
10-Gigabit Ethernet architectures edit
Half duplex is explicitly forbidden!
Future of Ethernet edit
It has won on the LAN over all other technologies. It will get faster - and faster - and faster...
Quality of service was deemed impossible, but it is has proved itself not to be. ATM is becoming redundant and both IP Telephony and Video multicast is perfectly possible over Ethernet today.
