SUMMARY:UTM Lab Meeting\: An Adaptive Cross-Layer Adaptation Framework for Media delivery over Heterogeneous Networks
DTSTART:20080515T130000Z
DTEND:20080515T140000Z
DESCRIPTION:Streaming applications in distributed systems are facing d
 ifferent problems at different layers of the Open Systems Interconnect
 ion (OSI) stack. Requirements regarding bandwidth\, delay\, jitter\, v
 ideo and terminal characteristics (temporal and space scalability) and
  user's preferences come together to influence the architecture of mul
 timedia delivery services with particular quality-of-services (QoS). H
 owever the Internet architecture is only capable to support best-effor
 t services\, with varying network conditions during multimedia deliver
 y. Currently\, a multitude of protection and adaptation strategies exi
 st at different OSI layers\, however these strategies are independent 
 of each other. To improve the perceived media quality delivered to end
  users over heterogeneous networks\, QoS strategies should combine mec
 hanisms at different layers\, including application layer\, transport 
 layer and data link layer. In this paper\, we formalize the problem of
  multimedia streaming application over heterogeneous networks\, then d
 iscuss the challenges and finally present a putative architecture.
