A node can transmit its high priority data by withholding a pass-by low priority data on the ring. This significantly reduces the access latency and cell delay variation of time delay data.

碩士 === 元智工學院 === 電機與資訊工程研究所 === 84 === In this paper we propose an enhanced protocol called
Preemptive Local Fairness Ring ( PLFR ) whih is a slotted
counter-rotating dual-ring MAC protocol. In PLFR, a local
fairness algorithm is used to maintain the fairness control of
high priority data between nodes on the ring. Local fairness
that is initiated only when starvation occurs can optimize the
benefits of destination stripping. In addition, local fairness
should only involve segments of interfering, as opposed to
global, nodes. Thus, several nodes may transmit data at the same
time. This significantly improves network bandwidth utilization.
To preempt low priority data on the ring, PLFR uses an insertion
buffer in the ring interface of each node. A node can transmit
its high priority data by withholding a pass-by low priority
data on the ring. This significantly reduces the access latency
and cell delay variation of time delay data. Furthermore, low
priority data is guaranteed to be delivered in sequence.
We define three different scenarios to compare the performance
between PLFR, Orwell and MetaRing. The simulation results show
that PLFR can provide the best quality of service for time delay
sensitive data.
