The future multimedia Internet needs mechanisms to provide QoS (Quality of Service) for users. Service curve (SC) is an effective description of QoS and SCED (service curve based earliest deadline first policy) is an efficient scheduling algorithm to guarantee SCs specified by users. Deadline calculation is the core of SCED. The unique treatable SC as we know is the concave piecewise linear SC (CPLSC). This paper re-derives out a more compact and clearer recursive relation of deadline
