The admission control issue in the design of a centralized bandwidth broker model for dynamic control and management of QoS provisioning is studied. A two-phase differentiated flow treatment based dynamic admission control scheme under the centralized bandwidth broker model is proposed. In the proposed scheme, the flow requests are classified into two classes and get differentiated treatment according to their QoS demands. We demonstrate that this admission control scheme can not only improve the resource utilization but also guarantee the flows＇ QoS. Furthermore, the admission control is divided into two phases： edge admission control and interior admission control. During the interior phase, the PoQ scheme is adopted, which enhances the call processing capability of the bandwidth broker. The simulation results show that the proposed scheme can result in lower flow blocking probability and higher resource utilization. And it also reduces the number of QoS state accesses/updates, thereby increasing the overall call processing capability of the bandwidth broker.

Simultaneous use of heterogeneous radio access technologies to increase the performance of real-time,reliability and capacity is an inherent feature of satellite-5G integrated network(Sat5G).However,there is still a lack of theoretical characterization of whether the network can satisfy the end-to-end transmission performance for latency-sensitive *** this end,we build a tandem model considering the connection relationship between the various components in Sat5G network architecture,and give an end-to-end latency calculation function based on this *** introducing stochastic network calculus,we derive the relationship between the end-to-end latency bound and the violation probability considering the traffic characteristics of *** results demonstrate the impact of different burst states and different service rates on this relationship,which means the higher the burst of arrival traffic and the higher the average rate of arrival traffic,the greater the probability of end-to-end latency *** results will provide valuable guidelines for the traffic control and cache management in Sat5G network.

作者： Debin Wei Junpeng Zhang Li Yang chengsheng pan Dalian University Nanjing University of Science & Technology

With the continuous development of satellites,the number and types of satellites continue to grow,people are increasingly demanding satellites,and the demand for satellite networks is *** to the wide coverage of the satellite,the long distance from the ground,the high dynamics,and many types,the difficulty of satellite network resource management is increased,resulting in a series of problems such as improper resource management and idle resources in the satellite *** view of the above problems,this paper firstly uses the coarse-grained method to classify the satellite network’s multi-dimensional resources and uses the characteristic parameters of the resource elements to perform fine-grained characterization and analysis of the satellite network resources;then,because the single resource element can’t meet the needs of various tasks of the satellite network,a multi-dimensional resource element association algorithm for satellite networks is proposed;finally,for the multi-dimensional resource collaborative optimization problem,a resource conversion strategy is pro proposed to solve the problem of resource shortage in satellite network *** simulation verification,the resource conversion strategy is better than the traditional method under the shortage of satellite network communication resources.

针对高动态卫星网络拓扑变化导致的网络更新期间可用路径失效,QoS需求难以满足的问题,提出了一种基于软件定义网络(SDN)架构的虚拟节点动态资源图多QoS约束路由算法(DRGVN-QR)。根据节点的切换状态、缓存以及链路的剩余带宽、时延等信息,结合虚拟节点的网络拓扑方式,建立虚拟节点动态资源图模型。根据资源图模型,建立最小路径代价的优化模型,利用蚁群算法(ACO)并发地为每个连接请求找到一段时间范围内的最优路径集合,并对信息素挥发系数的取值问题进行了讨论,以提升路径质量和算法性能。最后,为了适应卫星网络的时变性,设计一种幂数加权公式求出一段时间范围内的最优路径。仿真结果表明:DRGVN-QR算法能够规避路径失效带来的传输中断问题,提高网络QoS,与其他算法相比,该算法降低了平均端到端时延、网络丢包率和时延抖动。
