Resource management for continuous multimedia database applications

The uniqueness of continuous multimedia database applications lies in the fact that they require system support steady flow of media access data. In this paper we address the problem of system resource management for such applications. We introduce a session-based scheduling paradigm that, unlike traditional task scheduling, enables scheduling of all processing entities (threads, I/O processes, and buffers) across multiple system resources for guarantee of steady mediaflow. Under this paradigm, we develop an approach to on-line generation of session resource requirements based on resource allocation tradeoffs. Further, we develop a multidimensional “bin-packing” approach to allocation and scheduling of multiple resources for concurrent sessions. The goal is to minimize resource overheads and maximize the number of concurrent sessions while meeting session timing constraints and resource capacity constraints
