Audiovisual transmission - the „Core Application“ of the Future Internet (3D)IPTV, (3D)Internet-TV, 3D Virtual Worlds, VoIP etc. Bandwidth demands threat to exceed Internet infrastructure

investment by 60% to 70%(*)

Actual Internet has been designed for data Multicast is essential for many AV services

• But MC support of protocols rudimentary (even SCTP, DCCP etc.) Pure end-2-end paradigm (socket-2-socket)

• Alternatives like Split-TCP and Partial Reliability still in a niche Discussion around evolution vs. revolution ongoing

• Revolutionary thinking and evolutionary implementation is the solution

Transport must follow new paradigm Predictable Reliability under predictable delay (PRPD)

Ingerently multicast enabled

Requires even new theory (capacity for predictable reliability)

Our proposals AHEC Framework analytically and practically implemented

(next slide)

Extensions for link-2-link implementation ongoing

• Intelligent routers required, but evolutionary (each single one helps)!!!

Cost-based routing easily implementable

• SLA‘s can be integrated into framework easily

3D still is not integrated into web Content representation is 2D (DOM)

• Most representations (VRML, X3D) bypass DOM

Solutions required for Extending scripting languages (ECMAscript)

Notation to describe 3D scenegraphs (XML3D)

Flexible and extendible rendering (shader languages, ray tracing)

3D displays are still in their infancy Seamless choice between UHD-2D, HD-3D and SD-MV3D

still not feasible
