We address architectural and design considerations to a service-oriented architecture designed for the tactical
environment. This architecture, dubbed tactical service-oriented architecture, must be responsive to changing network
conditions and the quick addition or removal of network-enabled nodes. It must be supportive of a variety of
heterogeneous data networks and support translation of data between incompatible networks and systems. Additionally,
it will need to support the various operating environments of tactical edge assets. The architecture and design
considerations asserted in this paper are backed by lab test bed development, cooperative research with industry and
government labs, participation with relevant working groups, and participation in real-world exercises utilizing airborne
networks.
This paper reports on the results of testing General Dynamics AIS' Tactical Service-Oriented Architecture over wireless
communications during flight tests run at the Air Force's Airborne Networking CRADA in 2006. The wireless, tactical
domain presents a number of challenges. In particular, details of efficiency, reliability, and interoperability are a concern
in this solution.
Provided within this paper is discourse on why these details are relevant and how the approach taken addresses these
details in a tactical domain. Also shown is how this approach differs from a traditional enterprise Service-Oriented
Architecture. Finally there is a discussion of the results of the testing, as well as what steps can be taken in the future and
what challenges must be overcome.
