GPS analysis of multiple sessions with applications to admission control

AhstructIn this paper we introduce a statistical method tn analyze multiplexing of multiple sessions sharing link bandwidth using GPS scheduling. Our method is shown to substantially improve previous upper bounds for GPS scheduling of MMPP sessions, especially as the number of sessions increases. Application of analytical results to admission control indicate that by sharing handwidth using GPS among traffic classcs there are significant gains over systems that statically segregate the link bandwidth. This effect is quantified in several experiments where various combinations of source types are used. The gains are pronounced when bursty sources with stricter QoS requirements are used.
