Extending OSPFv3 to provide multi-class routing using multiple dynamic link metrics

As optical and RF links are deployed on airborne platforms, they will be integrated into networks. These networks will have links with metrics such as capacity, delay, and packet loss rates that may exhibit significant variation with time. To route traffic over such infrastructure, a routing system will need to be adaptive and efficient. Service requirements will differ among different classes of traffic. To address these challenge, we integrate new capabilities into the OSPF framework: continuous collection and distribution of multiple time-varying link metrics. We support multiple traffic classes by evaluating multiple cost functions and running multiple path selection procedures at each node.
