Extending tactical fleet communications through VoIP
Scott, David T.
MetadataShow full item record
TheNavy's Fleet is in need of tactical voice communication systems that are highly reliable, protected from cyber threats, and able to operate in a denied or degraded environment. Many of theNavy's current systems rely on outdated and inefficient technology, which reduces the overall effectiveness of our tactical communication channels and also limits the accessibility of these systems to communications challenged areas within ships. This research examines the capabilities, limitations, and overall performance of an integrated Voice over Internet Protocol (VoIP) system using four popular link layer protocols (i.e., Ethernet, 802.11n, 2.4 GHz 802.11ac, and 5 GHz 802.11ac) in an attempt to determine the feasibility of incorporating VoIP technology within Consolidated Afloat Networks and Enterprise Services and digital modular radio communication systems. The specific features compared in this study are VoIP network bandwidth consumption, overall network capacity between the four link layer protocols, VoIP codecs, VoIP call limits, intrusion detection system effects, and the effects of additional non-VoIP network traffic. The results of the study show that afloat tactical communications can be effectively enhanced by integrating VoIP intrusion detection systems monitored VoIP network applications with afloat communications systems, and by extending those systems with wireless devices utilizing the 802.11ac protocol.
