Abstract
An implementation method is described that efficiently achieves Quality-of-Service (QoS) criteria in a Media-on-Demand (MOD) server system. A MOD server system comprises a media server connected to a plurality of client stations via a shared transmission medium, such as a LAN network. To guarantee the QoS, the output rate of each data stream (of data requested by a client) needs to be specified individually. The inventive timer interrupt driven method achieves the necessary QoS, while reducing the complexity of conventional systems. In particular, a set of hardware timers is used to control the data rates. Each data request is handled by an individual timer, hence, different data streams may have different data request rates. Such design provides several advantages over other implementations, such as low overhead and high scalability.
