Multi-Service Provider Network Traffic Scheduling Method Based on Application Perception

Multi-service provider network traffic scheduling is an important research topic. Previous scheduling methods based on DNS resolves the issues of high latency and package loss due to cross-ISP access. However, there are still some problems like large bandwidth fluctuations and low bandwidth utilization in existing methods due to low scheduling accuracy. In this article, we propose a scheduling method based on application perception to solve these issues. Our scheduling method consists three components: application perception, traffic prediction of uplinks and network traffic scheduling based on DNS. It performs scheduling for each elephant flow application to improve scheduling accuracy. The experiment result shows that the application perception based method improves scheduling performance from both scheduling stability and bandwidth utilization.
