Abstract-An interactive video-on-demand (VoD) system allows users to access video services, such as movies, electronic encyclopedia, interactive games, and educational videos from video servers on a broadband network. This paper develops a performance evaluation tool for the system design. In particular, a user activity model is developed to describe the usage of system resources, i.e., network bandwidth and video server usage, by a user as it interacts with the service. In addition, we allow hatching of user requests, and the effect of such batching is captured in a batching model. Our proposed queueing model integrates both the user activity and the batching model. This model can be used to determine the requirements of network bandwidth and video server and, hence, the trade-off in communication and storage costs for different system resource configurations.

“…Early scalability work has been simulated to assess the resource needs of systems with hundreds of disks [18,19]. These show the levels of bandwidth required to support large numbers of users, but do not address the difficulties in building a system of that size.…”

Performance evaluation for VBR Continuous Media File Server admission control

SUMMARYA file server for continuous media must provide resource guarantees and only admit requests that do not violate the resource availability. This paper addresses the admission performance of a server that explicitly considers the variable bit rate nature of the continuous media streams. A prototype version of the server has been implemented and evaluated in several heterogeneous environments. The two system resources for which admission control is evaluated are the disk bandwidth and the network bandwidth. Performance results from both measurement and simulation are shown with respect to different admission methods and varying scenarios of stream delivery patterns. We show that the vbrSim algorithm developed specifically for the server outperforms the other options for disk admission especially with request patterns that have staggered arrivals, while the network admission control algorithm is able to utilize a large percentage of the network bandwidth available. We also show the interactions between the limits of these two resources and how a system can be configured without wasted capacity on either one of the resources.

“…This keeps each session busy until the next retrieval period when the buffer is ready to be refilled. (Buffer management policies to ensure continuous playout are described elsewhere [7,11].) If session i displays m frames per second, the file system must read exactly m × T period frames for session i in the working period.…”

“…Rangan et al [11] have developed an admission control algorithm for determining when a new concurrent access request can be accepted without violating the real-time constraints of existing sessions. Gemmell and Christodoulakis [7] have established some basic principles for retrieval and storage of delay-sensitive multimedia data.…”

Abstract-One approach to supporting continuous media traffic is via resource reservation at connection establishment time. The shortcomings of this approach are the lack of flexibility in re-negotiating bandwidth parameters after connection establishment and the inability to react to changing server load conditions. In this paper we propose a "selected access scheme" for re-negotiating continuous media delivery from a video-on-demand server. We consider the overall system perspective on resource availability rather than a per-connection resource management scheme. The selected access scheme is combined with data placement strategies for the server to dynamically access desired video frames from a shared storage device. This approach is especially suitable for video data compressed and stored using an inter-frame encoding scheme such as specified by the MPEG standard. Simulation results show that the proposed model can utilize server bandwidth, improve the reliability of playback, reduce the buffering needed, and support VCR-like functions without blocking user access to the storage device.
