abstract = {In this paper, we present a Quality of Service (QoS) negotiation scheme for efficient failure recovery in multi-resolution video servers with disk arrays. This scheme exploits multi-resolution property of video streams by negotiating service resolutions in order to provide graceful QoS degradation when a disk fails. Using the proposed scheme, not only can we increase the number of admitted clients greatly when all disks are operational but also utilize server resources efficiently. Furthermore, it can provide each client with acceptable QoS even in the presence of disk failure while maximizing server-perceived rewards. The effectiveness of the proposed algorithm is evaluated through simulation-based experiments.},
