¿µ¹®³»¿ë¿ä¾à | ITU-T Rec. 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 perclass 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 signaling these QoS routing parameters across networks employing different routing technologies, including IP-, ATM-, and TDM-based routing technologies. We propose extensions to signaling protocols such as SIP and RSVP-TE to support signaling of QSCs within and across networks. |
