Distributed schedule management in the Tiger video fileserver
William J. Bolosky, Robert P. Fitzgerald, John R. Douceur · 1997
Tiger is a scalable, fault-tolerant video file server constructed from a collection of computers connected by a switclied network.,All content files are striped across all of the computers and disks in a Tiger system.In order to prevent conflicts for a particular resource between two viewers, Tiger schedules viewers so that ihey do not require access to the same resource at the same time.In the abstract, there is a single, global schedule that describes all of the viewers in the system.In practice, the schedule is distrib&d among all of the computers in the system, each of which has a possibly partially inconsistent view of a subset of the schedule.By using such a relaxed consistency model for the schedule, Tiger achieves scalability and fault tolerance while still providing $e consistent, coordinated service required by viewers.
