On Paradigm Shift in Telecommunication Technologies: a Review of Pentagon's Approach

Manfred Sneps-Sneppe, Dmitry Namiot


The article is devoted to the discussion of the telecommunications development strategy. Communication specialists all around the world are facing the problem: shifting from circuit switching (CS) to packet switching (PS). The same problem is the main challenge for the U.S. Department of Defense. We discuss the Defense Information System Network move from circuits to packets, namely, “Joint Vision 2010” - the implementation of signaling protocol #7 and Advanced Intelligent Network, and “Joint Vision 2020” - the network transformation by the transition to Assured Services Session Initiation Protocol and Multifunctional SoftSwiches. We compare routers and switches and provide an example to illustrate the difficulties that complicate the transition from CS to PS and how to make this transition by hybrid CS+PS solutions. We describe some packet switching shortcomings during the implementation of Joint Vision 2020, namely, Joint Information Environment as a beautiful but unattainable dream, the failed GSM-O contract, and Joint regional security stacks failures. The Defense Department's newly released cloud strategy positions the general-purpose Joint Enterprise Defense Infrastructure (JEDI) cloud initiative as the foundation. The strategy emphasizes a cloud hierarchy at DoD, but JEDI cloud strategy leaves a series of unanswered questions relating to the interoperability of clouds that could spell disaster in the future. The JEDI cloud strategy has based on Artificial Intelligence Initiative. We conclude that the long-time channel-packet coexistence seems inevitable, especially in the face of growing cyber threats.
