scope:
The present document describes a framework for enabling the end-to-end QoS levels defined in TS 101 329-2 [1] to be signalled and controlled in TIPHON systems. The mechanisms involved operate between TIPHON terminals, IP telephony Service Providers (ITSPs), and network transport systems, and provide a flexible means for the dynamic allocation of QoS parameters across these entities in order to meet the QoS Service Classes defined in TS 101 329-2 [1]. The functional entities involved in the QoS signalling and control are defined, as are the requirements of the reference points between these functional entities. The QoS parameters and information flows used to establish the required Service QoS levels are also specified.
The Application Plane mechanisms described in the present document are intended to be independent of the transport QoS mechanisms used within the underlying IP networks.
The emphasis of the present document is on media QoS (primarily voice, but the mechanisms are also applicable to other media types). Issues related to performance of the signalling channels are outside the scope of the present document.
TS 101 314 [2] describes how this QoS framework fits into the overall TIPHON architecture and details of the signalling involved are described in TS 101 471 [3].
