Abstract

During the bandwidth on demand (BoD) procedure of the broadband satellite multimedia (BSM) system

the BoD performance is very sensitive to the bandwidth allocation period (BAP) and bandwidth allocation latency (BAL) by using periodical burst time plan generation (P-BTPG) method.The BoD model is given and the optimal-burst time plan generation (O-BTPG) method is presented by developing the optimal BAP and BAL.Then the large signaling overhead of O-BTPG is focused.An asynchronous burst time plan generation (A-BTPG) method which can generate the BTP asynchronously according to the bandwidth requirements is proposed.The expression of optimal schedule duration and schedule instant is developed

and the workflow is given.Two different bandwidth allocation algorithms were chosen to evaluate performance of the BTP generation methods.Simulation results show that A-BTPG method can be used widely.It can improve the bandwidth responsive ability of the system while controlling the BTP overhead.
