LONWORKS控制网络中的可预测p-CSMA协议

The Predictive p-CSMA Protocol in LONWORKS Control Networks

介绍在 L ONWORKS控制网络体系中 ,为了提高网络性能 ,在 MAC子层中所采用的与传统 Carrier Sense Multiple Access(CSMA)不同的可预测的 p -坚持 CSMA协议 ,并详细分析可预测的 p-坚持 CSMA协议的实现 ,比较了在不同通信服务下采用该协议 ,对冲突率和吞吐率的影响。

In this paper, the predictive p persistent CSMA, which is adopted in the LONWORKS control network to improve the performance of the network, is introduced and the implementing of this protocol is analyzed in detail. And its effect under different communication services is also compared.
