Ring Benefits
Shared-access/multi-access Network
Ability to Broadcast
Incremental Cost Growth
Fault Isolation, Simple Recovery
Great throughput
Usage of Point-to-Point Communication Link
Transmitted signal is regenerated at each node
Greater distances can be covered than with baseband bus
Ring can accommodate optical fiber links
Electronics and maintenance of point-to-point lines are simple
