Research on Scalability Model of DIS

随着分布交互仿真规模及复杂度不断地增加，系统可扩缩性是其面临的主要问题之一,影响系统可扩缩性的主要因素是系统资源受限，采用相应的技术手段可以提高系统的可扩缩性，本文深入研究了系统可扩缩性问题产生的根源，在此基础上提出了一个可扩缩性的数学模型，定性及定量地分析比较了当前各种技术措施的优缺点及效能，该模型对于指导仿真系统的设计具有重要的指导意义。

As the scale of distributed interactive simulation systems is increasing rapidly, the DIS faces the problem of system scalability. The main factor that influences system scalability is limited resources. Some technologies can be used to improve system scalability. This paper first proposes a mathematical model of system scalability based on the thorough studies of the reasons that cause the scalability problem, and then analyses the advantages and disadvantages of several classic technology measures. The model is very useful for the design of distributed simulation systems.
