摘要
首先介绍了网络拥塞及拥塞控制的基本概念,然后通过分析BACnet协议的特点和网络层报文的处理过程,阐述了BACnet网络拥塞控制机制的工作机理。在此基础上,分别建立了基于概率丢失和基于优先级的网络拥塞控制模型,从而为进一步改善BACnet网络的性能提供了新的思路和方法。
The paper first introduces the basic concept of network congestion and congestion control and discusses the mechanism of congestion control for BACnet by analyzing the features of BACnet protocol and the message processing for network layer. Then, the models of congestion control based on drop probability and priorities are established for BACnet, which provides some new viewpoints and methods for the improvement of the network performance.
