Technology (1)
Ethernet
- switched Ethernet - 10 Mbps to the desktop
- Fast Ethernet - backbone and desktop connectivity excellent price to port ratio
- Giga Ethernet - most promising LAN-backbone solution (IEEE 802.3z): high speed extension of Ethernet
ATM
- designed to provide QoS and flow control traffic sent in fixed-length, 53-byte cells, high cost
- connection-oriented technology (PVC, SVC)
- bandwidth: 25 Mbps, 155 Mbps (OC3), 622 Mbps(OC12)
- ATM succeeded in WANs
- LAN: ATM has difficulties to compete with Fast and Giga Eth
