Abstract
TCP/IP is the leading protocol used by networked applications the Navy requires to perform its mission. However, TCP/IP was designed for use in reliable, but possibly congested, wired networks, and thus does not support stealthy communication overintermittent and degraded wireless links as required by the submarine fleet.To enable IP-based applications in the submarine environment, CTI will investigate and define requirements for an integrated system, comprising enhanced Data Link and Transport layers, and an innovative Application Traffic Controller, that provide optimalSATCOM link utilization despite high/unstable Bit Error Rate, low bandwidth, long latency, and intermittent connection. For use under Low Probability of Detection / Intercept conditions, additional protocol enhancements will provide reliable transport ofIP traffic to the submarine without acknowledgement.This system will operate over any intermittent and degraded wireless media such as HF, UHF LOS/SATCOM, and sonar data transmission, providing significant benefit to both Commercial mobile platforms and Naval mobile assets such as surface ships, aircraft,brown-water Navy, and special operation forces.The severely constrained radio communication environment of a submarine coming infrequently to periscope depth, with a small antenna rising barely above the waves from a rolling platform, confounded by anti-jam and LPI requirements, is a worst case formobile wireless networking. Historically, the commercial wireless industry has not focussed on such harsh environments. Now, however, network operators and equipment manufacturers recognize a large and growing demand for reliable provision of multimediaservices to highly mobile users with extremely small devices, despite severe multipath, fading, interference, spectrum crowding, etc. Solutions to this Navy problem should be directly cross-applicable to the consumer space.
