In Chapters 4 and 5 we analyzed scheduling problems in which the task performance is subject to temporal restrictions such as release times or deadlines. The present chapter deals with a similar problem, but where the tasks are to be processed repeatedly, and each execution is restricted by release times and deadlines. The release times are regularly distributed over time with equal distances called the task period. Such tasks are called periodic. The deadline is usually assumed to coincide with the release time of the next period. In many applications such as real-time systems we find problems where sets of periodic tasks are to be processed on a single processor or on a distributed or parallel processor system.
