| Abstract: | The network bandwidth and storage I/O bandwidth are bottleneck parameters in realtime multimedia servicing, and they are interrelated. They must be considered simultaneously in designing real time server. The real time servicing process is analysed, and the maximum simultaneous subscribers and buffer size based on M k/M/1 queuing system are estimated. In order to improve its property, "Time Inverse Proportion Multisubscriber Servicing"(TIPMS)algorithm which is more effective than QPMS is proposed. At last, the performance of the TIPMS is evaluated. |
