DHS/NCS Priority Services By An Nguyen

Introduction: National Security/Emergency Preparedness (NS/EP) users rely heavily on public telecommunications networks to facilitate recovery operations for natural and/or man-made disasters events. They need to make authorized calls anywhere, anytime in times of network congestion. As commercial telecommunications infrastructures have evolved to IP-based technology (e.g., IMS, POC, etc.), end-to-end priority services (e.g., voice, video, , and data.) are needed to support NS/EP community. Problem Spaces: - End-to-end priority (i.e., distinguishing flows) - single domain (“own” resources), across domains - Security to ensure authorized ETS - Authentication, authorization, possibly confidentiality

Standards Efforts in Support of NS/EP Community: -IP Protocol Mechanisms: Internet Engineering Task Force (IETF) - WG’s that appear complimentary to NCS goals - IEPREP (informational) - TSVWG - SIP - NSIS - Regional Aspect: Alliance for Technical Industry Solutions (ATIS) - International Aspect: International Telecommunication Union – Telecommunication Sector (ITU-T) - Wireless Aspects: 3 rd Generation Partnership Project / 3 rd Generation Partnership Project 2 Potential Common Issues of Interests with DoD & NATO: - Interaction - Interconnectivity - Security
