Scope & Purpose

The Alliance for Telecommunications Industry Solutions (ATIS) Public Switched Telephone Network (PSTN) Transition Focus Group Report [ATIS-I-0000034] indicated several potential issues for the reliability and Quality of Service (QoS) aspects associated with the transition to IP-based packet networks and services. As stated in the Packet Technologies and Systems Committee (PTSC) Issue 129:

"There is a need to further review the reliability and QoS aspects within the PSTN Transition Focus Group Report. This report focuses on availability and robustness requirements and a strong requirement for ETS service reliability. In addition, there are no metrics or quantitative assessment methods specified. There are vague references to QoS parameters and a strong requirement for interconnection/interface QoS. In addition, there are no metrics or quantitative assessment methods specified."

Accordingly, the purpose of this ATIS Standard is to provide a comprehensive list of standards, technical requirements, and technical reports that have already been developed in areas of Internet Protocol (IP) packet reliability, priority, and QoS. The goal is to demonstrate that IP packet networks and services are subjected to a similar level of depth and rigor as the PSTN on issues related to reliability, priority, and QoS.

Standards, technical requirements, and technical reports related to IP packet network and service reliability, priority, and QoS are enumerated in this ATIS Standard. These documents provide an extensive set of metrics, classification schemes, and measurement parameters associated with IP packet network and service reliability, priority, and QoS. The list is comprehensive but by its very nature it presents a snapshot in time; new documents continue to be developed. The goal of this document is to demonstrate significant efforts undertaken by the telecommunications industry to deliver reliable services with desired levels of priority and QoS over packet networks.

The standards and documents listed here include work from several ATIS Committees, International Telecommunications Union Telecommunication Sector (ITU-T) Study Groups, and the Internet Engineering Task Force (IETF) and the 3rd Generation Partnership Project (3GPP).
