【摘要】 为了提高天基光突发交换网络的性能和服务质量,提出了一种适用于卫星光交换网络的汇聚算法。该算法在传统算法的基础上,通过对不同时间优先级业务进行自适应汇聚时间门限调整,有效降低高时间优先级业务的汇聚时延,并且保证了在汇聚过程中不引入额外的信令开销。仿真结果表明,与传统的基于混合门限的汇聚算法相比,基于QoS自适应的星载光突发交换汇聚算法在不同场景可以减少2.30%～9.06%的高时间优先级业务汇聚时延。更多还原

【Abstract】 In order to improve the performance and quality of service(QoS) of space-based optical burst switching networks, a burst assembly algorithm for satellite optical switching networks is proposed in this paper. Based on the conventional algorithm, the assembly delay for the high-time-priority service is effectively reduced by adaptively adjusting the assembly time threshold for the services with different time priorities. In addition, the additional signaling overhead is not involved. Simulation results show that, compared with the conventional assembly algorithm based on hybrid threshold, the assembly delay of the high-time-priority service can be reduced by 2.30%-9.06% in different scenarios for the proposed algorithm.更多还原
