A method for controlling congestion in intermittently-connected and lossy computer networks comprising: determining, at a local network node, a payoff score for each of a plurality of active flows of network traffic, wherein each active flow consists of a stream of in-transit packets at the local network node that come from a common source and share a common destination, wherein each active flow's payoff score is based on a pricing model that considers both a sojourn time and a position in a queue of each of an active flow's constituent packets; allocating unused buffer space across all active flows in the local network node based on relative traffic loads with a buffer-space allocation (BSA) agent; and controlling a rate at which packets from all active flows are received at the local network node with a hop-by-hop local-flow-control (LFC) agent according to each flow's payoff score.

A reinforcement-learning based queue-management method for undersea networks. In one embodiment, a computer-implemented method to shape traffic in a dynamic network, comprising measuring network states, classifying each of a plurality of packets into one of a plurality of traffic types based on quality-of-service requirements, defining a decision epoch interval, determining a policy with a plurality of neural networks and with a deep reinforcement learning agent that maximizes entropy-regularized long-term reward and produces a plurality of weighted fair-queuing weights based on an observation of the state of the queues at the decision epoch intervals, and using the policy to allocate predefined portions of the available transmission bandwidth across the plurality of traffic types by defining each type with a WFQ weight.

Reinforcement-learning based queue-management method for undersea networks

A device for communications comprising a power interconnect board, an acoustic board electrically connected to the processor board, a radio frequency board electrically connected to the processor board, and an optical board electrically connected to the power interconnect board.

Radio frequency optical acoustic communication modem

A system includes at least one transducer, connected via a transceiver to a switch, configured to transmit signals into and receive signals from an operating environment, a first and a second amplifier connected to the switch, a first filter connected to the first amplifier and a second filter connected to the second amplifier, a digital-to-analog converter (DAC) connected to the first filter and an analog-to-digital converter (ADC) connected to second filter, a digital system connected to both the DAC and ADC, and a processor connected to the digital system. At least one of the digital system and the processor has a plurality of software modules stored therein. One of the software modules is configured to reconfigure the operating frequency of the digital system based upon the operating frequency of the transducer.
