E.360.1, "Framework for QoS routing and related traffic engineering methods for IP-, ATM-, and TDM-based multiservice networks", provides a framework for QoS Service Classes (QSCs), called virtual networks (VNETs) in the E.360.x series. QSCs are defined as aggregations of individual service classes. Instead of having per-class parameters being configured and propagated on each network interface, classes are aggregated into QSCs having common per-QSC parameters (e.g., maximum bandwidth) to satisfy required performance levels. QSCs are known as VNETs in TDM networks, class types in IP/MPLS/DiffServ networks, and QoS classes in ATM networks. In this Recommendation we identify QoS routing functions and associated parameters, which include: a) bandwidth allocation/protection, with traffic and QoS parameters; b) routing priority; c) queuing priority; and d) class-of-service identification, with service identity and QSC/VNET parameters. We propose means of signalling these QoS routing parameters across networks employing different routing technologies, including IP-, ATM-, and TDM-based routing technologies. We propose extensions to signalling protocols such as SIP and RSVP-TE to support signalling of QSCs within and across networks. Source ITU-T Recommendation E.361 was prepared by ITU-T Study Group 2 (2001-2004) and approved under the WTSA Resolution 1 procedure on 2 May 2003. ITU-T Rec. E.361 (05/2003) i FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations o
