(English Abstract)
Linux's network bandwidth reservation framework focuses on restricting rather than on resource guarantee. Therefore, it is difficult to support network-intensive real-time applications. In order to solve this problem, we propose a tool that guarantees network I/O bandwidth resources. The proposed tool performs schedulability analysis so that the network bandwidth reservation does not exceed the maximum bandwidth provided by the physical network. In addition, it dynamically restricts the resource usage of competing tasks to prevent interference due to the non-real-time network flow. It also limits the CPU bandwidth resources of the real-time network flows from being interfered by the CPU resource usage of the non-real-time network flows. Experimental results confirm that bandwidth resource guarantee is throughput successfully even in high performance network environment. Also it is confirmed that network bandwidth resource can be increased by taking additional consideration of CPU resource to guarantee network bandwidth.
