Handling mixed workload in streaming server becomes important issue as integrated file system gets momentum as the choice for next generation file system. In this article, we present novel apaproach of handling sporadically arriving non-playback related disk request while minimizing its inter-ference with the timely retrieval of data blocks for ongoing playbacks. The main idea of our approch is to extend the length of period in period based disk scheduling in multi-media streaming and subsequently a certain fraction of each period can be set aside for handling unexpected I/O reques.t We develop the length of period, request arrival rate, request service time, and P(jitter). This model is used to precisely compute the length of period and the respective buffer size. We present the result of simulation based experiment.
