摘要/Abstract

摘要：

针对当前仿真工具存在的问题，研究并开发实时网络仿真测试系统SiT4NET。首先，SiT4NET利用容器技术在保证节点独立性的基础上解决了有限仿真资源实现大规模网络节点部署问题，提升了仿真系统的资源利用率；其次，提出基于数据单元的节点间分组传输和系统级数据单元申请/回收机制，为网络的实时仿真提供核心支撑；再次，通过标准高层协议接口和内部分组格式及可重构的分组处理机制，降低了协议的仿真实现与目标平台之间转换的复杂度；最后，通过SiT4NET和OPNET平台搭建相同的卫星网络环境，设置多组仿真场景，对仿真结果进行比较和分析，说明SiT4NET可以满足大规模卫星网络性能仿真需求。

关键词: 容器技术, 实时仿真, 虚拟分组传输, 分级数据单元管理

Abstract:

Aiming at the problems above, a real-time network simulation test system named SiT4NET was studied and developed.Firstly, SiT4NET used container technique to solved the problem of large-scale network node deployment with limited resources on the basis of ensuring nodes’ independence, thus improved the resource utilization of the simulation system.Secondly, the packet transmission between nodes based on data units and the mechanism for requesting/retrieving system-level data units were innovatively proposed to provided a strong foundation for real-time network simulation.And thirdly, through the standard high-level protocol interface, internal packet format and reconfi gurable mechanism of packet processing, SiT4NET reduced the complexity of conversion between the simulation implementation of the protocol and the target platform.Finally, by set up the same satellite network environment on SiT4NET and OPNET platforms, set up multiple groups of simulation scenarios, compared and analyzed the results, it showed that this method could met the performance requirements of large-scale satellite network.

Key words: container technology, real-time simulation, virtual packet transmission, graded data unit management
