1 Administrative Domain RequestController Charact eristic parser Tool check Schedu le check Remote check Distribu tor PMC databasePMC controller Inter-domain controller RequestController Reqest Interface (access interface) Response Interface (inter-domain interface) AAA

2 RequestInterface – input message … Normally the client would specify either a characteristic or a (set of) tools, and the tools would be filled out by the domain interfaces Tools to use, ranked in order of preference Source and sink hosts A time specification Credentials for authorisation and authentication. This is an anyType element, for extensibility

3 RequestInterface – output message foo.bar SELECT * FROM measurements WHERE id=myuniqueid The location is of type anyType, so any sort of reference can be put in here (this SQLQuery is just an example)

4 RequestInterface - faults Faults are used to indicate failures. Gone wrong further information for some faults ToolUnavailableException CharacteristicUnavailableException TimeUnavailableException MalformedRequestException

5 ResponseInterface Takes a MeasurementRequest Returns a MeasurementRequest or one of the faults Both interfaces may add new source/sink elements: – Either may remove tool elements Either may add credentials
