Research on QoS guarantee algorithm for cloud navigation simulator network
[Objective]This study proposes cloud-based navigation simulator architecture and designs a web quality of service(QoS)assurance algorithm.[Methods]Virtualization technology is used to abstract the hardware devices of the cloud navigation simulator into logical resources,then Kubernetes technology is ap-plied to cluster the platform application services and manage and build the cloud navigation simulator plat-form architecture.Combined with software-defined network architecture to provide a networking scheme for the WAN of the cloud navigation simulator network,the overall framework of the algorithm is determined ac-cording to the characteristics of data heterogeneity in the WAN transmission process,while the feasibility of the algorithm is simulated and tested on the Mininet simulation platform,and traffic identification,data sched-ule viewing and multi-stream QoS assurance simulation scenarios are established.[Results]The simulation experiments show that CNS-QoSGA achieves more than 70% accuracy in traffic identification,56.2% im-provement in bandwidth and 21.4% reduction in delay compared to the traditional Dijkstra algorithm,and when multiple data streams coexist in the cloud navigation simulator network,CNS-QoSGA improves the sat-isfaction rate of both bandwidth and delay in the network compared to the equivalent routing algorithm.[Conclusion]The proposed algorithm calculates appropriate routing paths for QoS-demanding view data and guarantees the QoS of the network.
