Which algorithm is based on Jackson’s rule?(a) EDD(b) LL(c) EDF(d) LSTThe question was posed to me in my homework.This interesting question is from Aperiodic Scheduling topic in section Embedded Operating System, Middleware and Scheduling of Embedded Systems

Answer»

Right answer is (a) EDD

For EXPLANATION I would SAY: The EDD or earliest due date is based on Jackson’s rule. The Jackson’s rule states that for a given a set of n independent tasks, any algorithm that executes the tasks in the order of nondecreasing deadlines is optimal with respect to reducing the maximum lateness. EDF is the earliest DEADLINE FIRST, LL is the least laxity and the LST is the least slack time first.
