摘要
The network resource allocation in SDN for control applications is becoming a key problem in the near future because of the conflict between the need of the flow-level flexibility control and the limited capacity of flow table. Based on the analysis of the difference of the definition of network resource between SDN and traditional IP network, the idea of the integrated allocation of link bandwidth and flow table for multiple control applications in SDN is proposed in this paper. Furthermore, a price-based joint allocation model of network resource in SDN is built by introducing the price for each of the resources, which can get the proportional fair allocation of link bandwidth and the minimum global delay at the same time. We have also designed a popular flow scheduling policy based on the proportional fair allocation of link bandwidth in order to achieve the minimum global delay. A flow scheduling module has been implemented and evaluated in Floodlight, named virtual forwarding space (VFS). VFS can not only implement the fair allocation of link bandwidth and minimum delay flow scheduling in data plane but also accelerate packet forwarding by looking up control rules in control plane.
