摘要/Abstract

摘要： 传统的卫星网络通常将控制层和数据层集中在同一网络设备中，使得网络结构复杂、带宽固定、资源利用率差，而软件定义卫星网络（SDSN）架构能实现卫星资源的有效管理，提高资源利用率，为多波束间切换机制提供有效的技术支撑。针对具有多波束覆盖的SDSN，提出了一种多决策指标切换（MDIH）机制。首先，分析了传统切换机制的缺陷，确立了基于SDSN的切换框架。其次，在传统信道预留机制的基础上，引入时间门限的概念，使得切换机制能够精确触发；同时，在切换决策过程中，采用MDIH算法来确定用户的切换优先级，决策粒度细。最后，给出了一种抽象化多决策指标实例，进一步体现了MDIH算法的可扩展性。

Abstract: The traditional satellite network usually concentrates the control layer and data layer in the same network device, which leads to more complex network structure, fixed bandwidth and poor resource utilization rate. The software-defined satellite network (SDSN) architecture can effectively manage the satellite resources, improve the utilization of resources, and further provide effective technical support for the multi-beam handover mechanism. In this paper, a multi-decision index handover (MDIH) mechanism is proposed for multi-beam coverage SDSN. Firstly, we analyze the shortcomings of traditional satellite networks' handover mechanism and establish a handover framework based on SDSN. Secondly, we further introduce the concept of time threshold to ensure the accurate trigger of handover strategy based on the traditional channel reservation mechanism. In addition, the MDIH algorithm is used to determine the priority of users' handover in the handover decision process, which makes the decision granularity more fine-grained. Finally, we give an instance of the MDIH algorithm to further demonstrate the scalability of our handover mechanism.

Key words: software-defined satellite network (SDSN), beam handover, multi-index decision-making, channel reservation, time threshold
