Current systems, such as UNIX, lack necessary scheduling and resource management mechanisms in supporting specific timing requirements, thus multimedia applications cannot run smoothly on top of them. Aim on solving these problems, in this paper we propose a system framework, the Lyra, for supplying multimedia applications with sophisticate timing controls. Lyra enhances conventional systems in supplying firewall protections among multimedia applications, while also considering I/O interference, and aims on processing digital data on time. Empirical evaluations show that Lyra not only practically provides better QoS supports than conventional systems, but also performs better than several works that aim on similar problems.
