| Grand Unified Theories | |
| Diversity in the Gene Pool? | |
| Algorithm and Data re-use? | |
| What we can do? | |
| What scary stuff is coming over the horizon? |
| Motley crew of multicast… | ||
| 12 years of IDMR etc work has led to a lot of multicast routing algorithms | ||
| 4 years of RMRG work has led to rather a lot of reliable multicast protocols | ||
| 2 o 3 years of ffnet/yall work has led to a number of application level multicast schemes | ||
| Can we put it all together? | ||
| Can we avoid folks re-inventing wheels? | ||
| Tree construction | ||
| Switch, router, server support for GRA | ||
| Re-visit namespace | ||
| Re-visit with security and billing | ||
| Active Nodes? | ||
| Key to Deployment: as many choices as possible! | ||
| When you come up with a membership control, access control, new tree building, maintenance, sub-tree, discovery, filter algorithm: | |
| Think 3 levels – think link (shared v. NBMA); think IP friendly; think application! |
| Can we get synergy between different groups – e.g. digital broadcast, and terrestrial ISPs; router vendors; application and content service providers? | |
| New sub-effort within RMRG (Now that RMT and PIM-SSM/bidir are everyday business spunoff)? |
| Can we think incentives and see how to mix them – as per qos, this is a multi-disciplinary activity – needs: | |
| Protocols & Information Theory… | |
| Economics | |
| Operations | |
| Stats/measurement/control/queueing etc |
| New new thing is deployment of DWDM | |
| Optical cross connects go quite fast (e.g. multiple OC-48 Nortel kit is commonplace now) | |
| Cannot do electronics to keep up and wavelength assignment needs some control algorithms | |
| Ideal place to put multi-level motleynode. |
