    Page 9 (physical) of the textbook you’ve quoted defines your parameters as:

    • r,task release time, i.e. the triggering time of the task execution request
    • C,task worst-case computation time, when the processor is fully allocated to it
    • D, task relative deadline, i.e. the maximum acceptable delay for its processing
    • T, task period
