here is something to whet the appetite (and stress the reply

"Joint Receiver, Channel and Source coding for re-routable multimedia flows"


Integrated Services in the Internet have largely mimiced Bearer
Service Classes in Telecom (B-ISDN) Networks. This is a mistake of the
first order. The strength (promise) of the Internet lies in its
origins - soft statem survivability, and cheap and cheerful
feasibility.

The design of flow types must recognize this. To retain the advantages
of the datagram model, but incrementally add soft qos, we must evolve
new models of contracts based in statistical contracts, rather than
bounds (e.g. for minimum delay and throughput as per Guaranteed
Service and WFQ/Parekh/PGPS services), and thus permit survivable,
scalable group, mobile, and other, as yet unforeseen communication
patterns to enjoy better effort services. Considering the receiver and
sender adaptive models leads us to routing processes that are also
approximate (e.g. diffusive, multipath cluster based routing), rather
than simplistic hierarchical area based schemes like QOSPF and PNNI.

By considering an ensemble of paths, and scalable coded flows, we
arrive at the QoS descendent of the original Internet best effort
service.
