Objectives 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 applied to cluster the platform application services and manage and build the cloud navigation simulator platform 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 according 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 schedule 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% improvement 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 satisfaction rate of both bandwidth and delay in the network compared to the equivalent routing algorithm.
Conclusions The proposed algorithm calculates appropriate routing paths for QoS-demanding view data and guarantees the QoS of the network.
