Shared media LANs

• Limits to Shared Media LANs

  • FDDI, 100Base-X, 100VG-AnyLAN all shared media LANs
    • Only one station can transmit at a time, causing latency
    • Every station hears every message, so as the number of stations grow, the LAN saturates
  • 100 Mbps speed only delays saturation
