FDDI Protocol
Similar to Token Ring IEEE 802.5, eg priorities
Except supports multiple tokens
- in a large network, several frames may fit on the ring at same time
- if station waited for frame to come 'round before regenerating token, bandwidth wasted, especially in large ring at 100 Mb/ s
- instead, station regenerates token as soon as the current frame has been sent
Except capacity allocation
- supports both stream and bursty traffic
