Abstract
Large-scale not-for-profit Internet Service Providers (ISPs), such as National Research and Education Networks (NRENs) often have significant amounts of underutilized bandwidth because they provision their network capacity for the rare event that all clients utilize their purchased bandwidth. However, traffic policers are still applied to enforce committed purchase rates and avoid congestion. We present the design and initial evaluation of an SDN/OpenFlow solution that maximizes the network link utilization by user-defined fair allocation of spare bandwidth, while guaranteeing minimum bandwidth for each client.
