Scope, Purpose, & Application

This document focuses primarily on media flow performance, specifically the transfer of voice, all forms of video, high fidelity audio, and other information that is time sensitive. Voice over Internet Protocol (VoIP) and multimedia applications are evolving to use NGNs that are packet-based. These services use multiple broadband QoS-enabled transport technologies where service related functions are part of the service stratum and are independent of technologies in the transport spectrum.

Section 6 discusses NGN NS/EP services and how new proposed security features could improve their performance and survivability during heavy network congestion.

The NGN architecture is defined in ITU-T Y.2011 and ATIS-1000018, NGN Architecture. The performance objectives for Internet Protocol (IP)-based services are described in ITU-T Y.1541. With the use of resource and admission control functions defined in ITU-T Y.2111, QoS-related decisions are made based upon service-level agreements, service priority and multiple domains.

ATIS-0100014, Information and Communications Security for NGN Converged Services IP Networks and Infrastructure, discusses the security requirements and mechanisms to be considered in offering NGN services. The use of the security mechanisms discussed in the ATIS-0100014, such as various forms of encryption, impact the QoS objectives and requirements for offered services. This document addresses the selection of appropriate security support while meeting the performance (QoS) objectives, especially with consideration for NGN NS/EP services, which aim to provide priority telecommunications capabilities over NGN networks to personnel involved with national security or public safety. It is based off of the legacy Government Emergency Telecommunications Service (GETS), which was created in the mid-90s to provide the same capability over the Public Switched Telephone Network (PSTN).
