Performance of Token Rings
Special Case: Light Traffic Load
Under light traffic load, meaning S is approximately 0, the average time waiting for service of previous arrivals into the network is negligible. Thus the average transfer delay can be approximated by:
Special Case: Small Normalized Ring Latency
With a small normalized ring latency, meaning a' is approximately 0, the average transfer delay for fixed length frame is approximately:
and for exponentially distributed frame lengths, the average transfer delay is approximately:
These results are independent of the token management technique.
