基于LonWorks技术测控网络的流量控制方法研究

Study on traffic control of LonWorks-based monitor and control networks

采用速率反馈方式的流量控制策略,在LonWorks总线网络节点上增加控制器和缓冲队列,是改善网络的公平性,提高网络的信息吞吐量,降低网络反馈信道的错误率的有效方法.该策略及算法不仅可优化LonWorks总线网络的通信传输质量,而且对于解决其他包含CSMA协议的工业控制网的同类问题也有参考价值.

The rate-based feedback traffic control policy is introduced in this paper. Trough an additional controller and buffer queue in LonWorks-based fieldbus networks, which is effective method to improve the fairness of networks, increase the throughput and decrease error rates on network chamlel. The control policy and algorithm are applicable not only to optimize the quality of communication and transmission information in LonWorks fieldbus networks, but also to resolve the class of case in others kind of industrial network based on CSMA protocol.
