Abstract

This article gives an overview of the effort underway in ITU-T SG 13 on an architectural framework for QoS support in packet networks, with a focus on IP. Provisionally named Y.qosar, the framework is to be published as a new ITU-T Recommendation. At the center of the architectural framework is a set of QoS network mechanisms distributed across three logical planes (the control, data, and management planes) to control network performance. Ultimately the network mechanisms are to be used in combination to deliver the satisfactory collective effect of service performance. The article also provides pointers to standards efforts dealing with specific QoS network mechanisms.
