Issue 5060: Figure 43 you include a QoS, needs clarification (uml-scheduling-ftf)
Source:  (, )
Nature: Uncategorized Issue
Severity: 
Summary: In Figure 43 you include a QoS constraint to represent end-to-end response times. But it is not clear how you do this. If WCRT:80 is a tagged value, this cannot be represented in UML 1.3 because we can only associate a tagged value to a single element, and we cannot associate it to two messages, and if we do the association to the object we cannot identify the end points. Another alternative would be use constraints to represent the WCRT:80 condition (we can associate the constraint to more than one UML element), but you do not clarify this

Resolution: Closed, no change

OK, change the diagram to reflect the association to SAStep.

Figure 43 you include a QoS, needs clarification

In Figure 43 you include a QoS constraint to represent end-to-end
response times. But it is not clear how you do this. If WCRT:80 is a
tagged value, this cannot be represented in UML 1.3 because we can
only associate a tagged value to a single element, and we cannot
associate it to two messages, and if we do the association to the
object we cannot identify the end points. Another alternative would be
use constraints to represent the WCRT:80 condition (we can associate
the constraint to more than one UML element), but you do not clarify
this
