In this paper, we address the problem of efficiently streaming a set of heterogeneous videos
from a remote server through a proxy to multiple asynchronous clients so that they can …

The efficient distribution of stored information has become a major concern in the Internet
which has increasingly become a vehicle for the transport of stored video. Because of the …

We consider the delivery of video assets over a best-effort network, possibly through a
caching proxy located close to the clients generating the requests. We are interested in the …

Due to the high bandwidth requirement and rate variability of compressed video, delivering
video across wide area networks (WANs) is a challenging issue. Proxy servers have been …

We study caching strategies for proxies that cache VBR-encoded continuous media objects
for highly interactive streaming applications. First, we develop a model for streaming VBR …

Internet streaming applications are affected by adverse network conditions such as high
packet loss rates and long delays. This paper aims at mitigating such effects by leveraging …

The bandwidth-intensive and long-lived nature of high quality digital video makes it a
challenging problem to transmit such video over the Internet. In this paper, we propose a …

This letter elaborates on a scheme that combines batch patching at an origin server and
prefix/interval caching at an edge server receiving the clients' requests. We derive a cost …

In wide-area and heterogeneous environments, it is necessary to deploy media gateways at
strategic locations within the networks, in order to deliver customized and compose-able …
