....MPEG streams from a single disk drive. These streams would have to be delivered to workstations on the campus LAN where they can be decoded and played out. In particular, we wanted to make an evaluation of how well multiple streams are supported by the disk scheduling strategy discussed in [1, 2, 3] by the use of a working prototype. A secondary objective is to make a modular testbed available that will enable us to evaluate various VOD scenarios and server subsystems. Unlike conventional data types, video data has strict timing and large bandwidth requirements. Further the long and ....

....when peak demand coincides with high density access. There can be occasional high demand periods when the density of access is low. In other words, there are a large number of users who all request different content. The case for service scaling in such scenarios has been made by Chen et al. [2, 3]. Our proposal for rate adaptation works on the same philosophy of QoS scaling albeit in a different flavor. As a consequence, our scheme also supports limited service scaling during peak overloads. Service scaling is achieved as follows during periods of overload, we do not read the optional ....
