Abstract:
In tactical networks, a hierarchy of queues complements each other to handle changing communication scenarios. Command and control QoS-constrained messages are in the first queue. These messages are fragmented into IP packets and stored in a queue (second) to be sent to the radio buffer (third), which has limited space and can overflow.
We hypothesize that these three queues can handle ever-changing user(s) data flows (problem A) through ever-changing network conditions (problem B) using cross-layer information exchange, such as buffer occupancy, data rate, queue size, and latency.
Two stochastic models create QoS-constrained message sequences (A) and ever-changing network conditions (B). To test our hypothesis, we sketch a control loop to shape A to B using model A|B’s enforcement points at the system’s incoming/outgoing chains and control plane.
Next, we discuss experimental results in a VHF radio network with data flows that overflow the radio buffer over ever-changing data rate patterns. We discuss quantitative results for problems A, B, and A|B.
