  5. Paramters • Data coherency: QoIFilter • Input: list of Dimension Data • Output: list of Coherency Data • Data buffer: TemporalBuffer • Input: list of Dimension Data • Output: list of Dimension Data • Data adaptation • Input: list of Dimension Data • Output: list of Dimension Data • Probe • Data grouping: impl. at probe's collector • WS data source: XPATH to de-group QoS data • Ex. <definition name="fr.orange.monitoring.QoIFilter" extends= "cosmos.ContextNode" arguments="coherency,age"> <definition name="fr.orange.monitoring.DataBuffer" extends="cosmos.ContextNode" arguments="age"> <definition name="fr.orange.monitoring.DataAdaptor" extends="cosmos.ContextNode"> <definition name="fr.orange.monitoring.Probe" extends="cosmos.ContextNode" arguments="frequency"> <component name="collector" definition='open probe impl'> </definition>

  7. Data coherency • QoI • Coherency • Age • Data Adaptation • Probe • RemoteQoSPull/RemoteQoSPush interface • Periodic pull: frequency coherency=10secs now Sliding direction Speed (S) Essence (E) time Valid coherency data age = 1 min Number of dimension is large -> complexity of this process?
