Method of providing QoS for a flow

Procédé pour fournir une qualité de service

Verfahren zur Bereitstellung von QoS

Abstract

The invention concerns a method of providing QoS for a flow associated with a client application in a network (1), and a QoS manager (12) to execute this method. The network comprises said QoS manager (12), a QoS policy holder (13), one or more QoS devices (14, 15, 16), and a control point (11) associated with the client application. Moreover, the network (1) supports a Universal Plug and Play QoS service. The QoS manager (12) calculates a topology of the network (1) on flow setup and requests traffic policy data from the QoS policy holder (13). The QoS manager (12) submits traffic descriptor data based on said traffic policy data to the one or more QoS devices (14,15,16) for configurating said QoS devices (14, 15, 16) for handling the flow, The QoS manager (12) subscribes to events of the one or more QoS devices (14, 15, 16). The control point (11) subscribes to events of the QoS manager (12). On detection of a QoS device event by the QoS manager (12), the topology of the network (1) is re-calculates by the QoS manager (12) for determining a topology change. The QoS manager (12) checks whether the topology change affects the flow. If the flow is affected by the topology change, the QoS manager (12) triggers suitable measures.
