Popis: The current generation of long-range, high capacity, military radios are stove-piped systems that work well in a homogeneous environment, but require significant setup and configuration to interoperate with other radio systems. Each radio provides a subset of disparate link information in nonstandard interfaces and has built-in home-grown or industry-based routers running potentially different routing protocols. In a heterogeneous radio system airborne environment, wireless link characteristics change rapidly, often requiring direct link feedback from the radio to make routing decisions. In recent years, there has been a number of work in developing a common radio-to-router interface that standardizes a subset of per-link information to pass to the network layer for use in dynamic MANET routing. While simulations and emulation tests can provide a baseline for how systems will perform, field-tests are crucial to demonstrate capabilities in real-world operating environments. In this paper, we present measurement results from a field test involving three airborne and two ground assets with various radio systems that test an implementation of RFC4938, a radio-to-router interface protocol, and its interaction with a modified OSPFv3 routing protocol to support dynamic link metrics and OSPF cost generation. The assets participated in the exercise formed a high capacity, dynamically routed aerial IP backbone made of heterogeneous radio technologies over 250 nautical miles (Nm), allowing the passing of military operational traffic.1
