基于实时性区分的舰载网络传输优化算法

Real-time identification based shipborne network transmission optimization algorithm

  • 摘要:
      目的  提出一种基于实时性区分的舰载网络传输优化算法−实时延迟(real time delay based,RTDB)算法。
      方法  该算法根据不同类型报文的实时性需求对其进行分类,并指定不同的阈值,通过对报文的类型进行判定和处理来保证各报文的实时性需求。结合美国海军广泛使用的战术数据链Link11,Link16对算法增益进行分析。
      结果  理论分析表明,在业务数据量大于网络传输带宽,或业务生成率满足确定性分布的情况下,RTDB算法能带来一定的时延增益;使用NS3作为仿真平台并进行仿真分析,仿真结果与理论分析结果基本一致。
      结论  所提出的RTDB算法部署代价小,对于急需进行海军现代化改装的国家具有较重要意义。

     

    Abstract:
      Objectives  This paper proposes a real-time identification based algorithm named RTDB.
      Methods   The algorithm classifies messages by the real-time requirements of different types of them, and assigns different thresholds to them. The algorithm gain is then analyzed by combining Link 11 and Link 16, which are widely used by the US Navy.
      Results  Theoretical analysis shows that the algorithm can bring a certain delay gain when the data rate is greater than the network transmission bandwidth or the generation rate satisfies the deterministic distribution. In this paper, NS3 is used as the simulation platform, and the gain of the proposed algorithm is simulated and analyzed, yielding the same results as the theoretical results.
      Conclusions  The deployment cost of the proposed RTDB algorithm is small, and it can be of great significance for countries that urgently need to modernize their navies.
