President's National Security Telecommunications Advisory Committee: Report on National Security and Emergency Preparedness Internet Protocol-Based Traffic   [open pdf - 508KB]

"Over the past several decades, the President's National Security Telecommunications Advisory Committee (NSTAC) has provided guidance on how to prioritize NS/EP traffic in times of crisis. Specifically, the NSTAC's industry partners developed recommendations to the President regarding NS/EP communications traffic prioritization that prompted the Department of Homeland Security's (DHS) National Communications System (NCS) to create the Nation's current priority service programs-Government Emergency Telecommunications Service (GETS), Telecommunications Service Priority (TSP), and Wireless Priority Service (WPS). With these services, NS/EP users have a high probability of completing calls even during times of network stress. Service providers have invested billions of dollars to both transform and augment their circuit-switched networks to incorporate the use of technologies based on Internet protocol (IP). As the core networks universally evolve from circuit-switched to packet-based service technologies, it is important for the Federal Government to consider the impact of this evolution on the delivery of NS/EP communications traffic. Although the rapid growth of the Internet has led to exciting new services for customers, such as Voice over IP (VoIP), these technological advancements have also altered the NS/EP priority-services network environment. To address the need for the continued delivery of NS/EP traffic over packet-based networks, during the 2007 NSTAC Meeting, the Assistant to the President for Homeland Security and Counterterrorism requested that the NSTAC examine concerns regarding the risk, if any, to IP-based NS/EP communications traffic, including VoIP, during times of perceived abnormal conditions or network duress."
