Figure Me.01-I02 – MetricDefinition and MetricDefinitionCategory

<font color="#29313b">The following illustration shows examples of categories, as instances of MetricDefinitionCategory. </font><br/><font color="#29313b">Two categories are represented: </font><br/><ul>
<li><font color="#29313b">CFS-level performance, </font></li><li><font color="#29313b">and Network-level performance, which covers both Resources and RFSes. </font></li></ul>
<font color="#29313b"> “Weekly % of Good Video Sessions for All Users” and “Estimated MOS of a video session” MetricDefinitions would fall within the former category, while “Layer 3 packet roundtrip delay” would fall within the latter. </font><br/><font color="#29313b">The optional linkageReference attribute would refer to some other categorization approaches such as Frameworx domains or Business Architecture domains. </font><br/><font color="#29313b">Relationships (possibly hierarchical) between MetricDefinitionCategory instances are possible using the MetricDefinitionCategoryIncludes association: in this example, CFSPerf would “include” NetworkPerf in the sense that CFSPerf metrics rely on NetworkPerf metrics.</font><br/><br/>
