Real-time scheduling, or scheduling with respect to a deadline, is critical in many application areas such as telecommunications,
control systems, and manufacturing. This paper presents a novel approach to real-time scheduling based on a queueing theory
model. Using real-time queueing theory (RTQT), one can analytically determine the distribution of the lead-time profile (i.e.,
the time until the deadline is reached) of customers waiting for service. Emphasis is placed on the development of the equations
used to determine the lead-time profile distribution. The development of the GI/G/1 case is presented and confirmed using
simulation. Simulation results confirm prior research for the M/M/1 and GI/M/1 case. As a practical application, RTQT is used
to implement a packet admission control algorithm for a telecommunications network. Using this algorithm, packet lateness
was reduced by up to 31%.
