ABSTRACT
A Video­on­Demand (VoD) service o#ers a large selection
of videos from which customers can choose. Designers of
VoD systems strive to achieve low access latency for cus­
tomers. One approach that has been investigated by several
researchers allows the server to batch clients requesting the
same video and to serve clients in the same batch with one
multicast video stream. This approach has the advantage
that it can save server resources as well as server access and
network bandwidth, thus allowing the server to handle a
large number of customers without sacrificing access latency.
VoD server replication is another approach that can allow
a VoD service to handle a large number of clients, albeit at
