J. Petersen et C. Zang, BUSY PERIODS IN THE OUTPUT OF A TIME-DISCRETE QUEUING SYSTEM NGEO D/1/, AEU-INTERNATIONAL JOURNAL OF ELECTRONICS AND COMMUNICATIONS, 51(5), 1997, pp. 263-266
For a time-discrete queueing system NGeo/D/1 in steady state, with tim
e slots equal to the service time, the distribution of the length of b
usy periods is derived in closed form, using a kind of generalized Cat
alan numbers.
