基于SRTP的HLA底层通信机制的实现

高层体系结构HLA（High Level Architecture)是美国国防部DoD(Department of Defense)建模与仿真办公室DMSO（Defense Modeling and Simulation Office)提出的一个公共仿真框架，已被公认为是下一代分布式仿真的标准。重点研究了HLA底层通信机制的实现方案。采用一种可选择的可靠传输协议SRTP（Selectively Reliable Transport Protocol)来实现HLA底层通信机制，并对SPTP进行了必要的移植和改进，初步建立了一种有效的HLA底层通信机制，证明使用可靠组播通信协议来建立HLA底层通信机制的方案是可行而且有效的。

Using SRTP to Implement the Low -level Communication Mechanism of HLA

High Level Architecture (HLA) was developed by the Defense Modeling and Simulation Office (DMSO) of the Department of Defense (DoD). It has been recognized as the common standard of all distributed interactive simulations. In this paper, the implementations of HLA's low level communication is analyzed, an efficient solution: using Selectively Reliable Transport Protocol (SRTP) to implement the low level communication mechanism of HLA is introduced, some replantation and development for SRTP are advieved, and a fundamental low level communication mechanism of HLA is built. It has proved that using some reliable multicast protocol to implement the low level communication mechanism of HLA is practical and efficient.
