基于HLA体系结构的交互式网络仿真设计

提出利用交互式网络仿真技术构建对用户透明的网络仿真系统并真实再现通信网络的观点,指出使用高级体系结构(HLA)来加强网络仿真技术在交互式仿真操作中的应用,从而克服了现存网络仿真软件只能模拟固定参数的网络模型的缺点。详细讲述了将网络仿真软件和用户控制台以联邦形式加入HLA中,通过RTI这条“软总线”传递信息以实现两者之间的通信的方法。这样,传统的,以离散事件驱动而无法提供与用户接口的网络仿真软件就可以在运行中与用户交互,从而实现交互式网络仿真系统。

Interactive Network Simulation Technology Based on the High Level Architecture

The idea of modeling transparent network simulation to users and reappearing communication network realistically by utilizing interactive network simulation technologies was advanced. The application of network simulation technologies in interactive simulation through High Level Architecture (HLA) was pointed out. In this way, the shortcoming that current simulation software could only simulate network models with fixed parameters was conquered. Realizing communication between network simulation software and external users was implemented by joining network simulation software and user console into HLA, and exchanging information through RTI, which acts as a soft bus in the system. In this way, traditional discrete-event-driven simulation software, which could not provide interface to external users, is able to interact with users while running and thus interactive network simulation system is realized.
