Question 15/12 - QoS and performance coordination
(Continuation of Question 15/12)
Motivation
The widespread expansion of IP-based services, and the rapid change from a circuit-based network infrastructure to one that is packet-based, have created many performance and service quality issues. Additionally, even when the end-to-end path is all-IP, there are still many performance issues if demanding applications are to be satisfactorily supported. This Question is intended to provide cross-ITU coordination for the many aspects of Quality-of-Service (QoS); and to foster consistency among ITU-T Study Groups, as well as from other related bodies such as the IETF, so as to advance the interoperability of any QoS solutions. This coordination should be conducted by Study Group 12 as the Lead Study Group on QoS.
The following major Recommendations/Supplements/Handbooks, in force at the time of approval of this Question, fall under its responsibility: G.1000.
Question
Study items to be considered include, but are not limited to:
- Co-ordination of the studies carried out within ITU-T on QoS.
- Harmonisation among the various Recommendations and standards on QoS.
- Co-ordination of critical IP-related QoS issues across the industry, in cooperation with bodies such as the IETF, as appropriate.
Tasks
Tasks include, but are not limited to:
- Coordination of QoS-related activities in the ITU-T (ongoing), with the focus on identifying gaps in QoS standardization that present interoperability obstacles to achieving end-to-end
QoS.
- Coordination among various standards activities on QoS and collaboration with other standards bodies (ongoing), with an emphasis on interoperability.
- Make recommendations to TSAG and the TSB, as needed.
- Maintenance and possible revision of Recommendation G.1000
Relationships
Recommendations: G.1000
Questions: Any question in the ITU-T that has QoS or performance aspects
Study Groups: All ITU-T Study Groups with activities related to QOS.
Standardisation bodies: IETF, ETSI TISPAN, ATIS, IEEE
