Issue 5072: Definition of Abs Deadline=Release-time + Rel Deadline (uml-scheduling-ftf)
Source:  (, )
Nature: Uncategorized Issue
Severity: 
Summary: "One definition of Abs Deadline=Release-time + Rel Deadline, 
whereas we seem to mean something else in the spec, i.e abs is used when 
laxity is hard, rel is when laxity is soft"

Resolution: see above
Revised Text: Change definition of  Absolute Deadline of page 7-7 to "specifies the final instant by which the action must be complete, defined as the Relative Deadline + Release Time. This may be either a hard or a soft deadline."
Actions taken:
March 20, 2002: received issue
June 30, 2003: closed issue
Discussion: 
Definitions differ depending on the research center. Sidharth's definition comes from Liu Other groups measure time from system initiation, not release time. The definition in the profile (laxity) is unconventional. I suggest that we change the profile to agree with Sidarth (and Liu).  Resolution:
