Internetworking service architecture for transporting mission-critical data over heterogeneous subnetworks with probabilistic guarantees

We present the framework for a heterogeneous internetworking service architecture to provide probabilistic quality of service guarantees to short critical messages prior to transmission. The TCP/IP Internet is not suited to bear mission-critical data across administrative domain boundaries with stringent delivery requirements because Border Gateway Protocol obscures network state information. Critical messaging is useful in both military and civilian networks, and the adoption of an architecture designed for this service will greatly reduce overprovisioning costs. Leveraging software-defined network control concepts, we describe architectural modifications to the Internet to realize this service and discuss several algorithmic techniques to support its operation.
