A strategy for Continually reinventing the Internet
Questions: Need clarification about what you mean by architecture. We need architecture of back bone or end to end architecture ?
Larry: An end-to-end architecture
This talk does not have a wireless perspective; the red block contains everything you need to know about wireless. PlanetLab aims at virtualization of the backbone. Diff parties will control the 3 rd party software.
Dave: practically for this workshop – specific MREFC proposal. Need virtualized infrastructure; need core to reach out towards the edge. How to make this happen? challenge to L:
Reference wireless network.
Testing new hardware requires setting up the hardware on the rack.
How do I integrate new hardware with platlab or NLR.; virtualization model
Ans: virtualization happens w
Dave: the virtualization model may not serve someone who wants to observe bits on a pipe.
Optical switch overlay; connect to one of the bb routers in the rack directly; Gary Minden thought this was cheap virtualization; Different types of for virtualization in differ parts would be desired. An architecture which has packets at some levels and aggregation else where leads to a messy testbed.
Peter: Virtualization picture with red blocks; virtualized wireless networks is an important topic of discussion
Mario: PlanetLab has dedicated pipes for each experiment. It does not allow studying interaction between experiments; This is inconvenient unless you assume separate chunks in Internet in future.
Gary Minden: What is the final value of such testbeds to the country?
Larry: correct security risks.
Wade: how to ring in the common man?; Larry: plant lab already doing that.
Badri: Cellular industry – ossification taken to an extreme;
Ray: two other projects building such testbeds/
Ray: Wireless is represented as a tiny link in your slides. But one cannot draw a boundary of influence with wireless networks. Meaningful virtualization of radio devices also needed.
John Heidemann: treating wireless networks as a edge leads to loss of opportunity. Need a wireless domain for virtualization
Ray: Wireless Adhoc Multihop cannot be encompassed here. So cannot write wireless as a separate cloud.
Nitin Vaidya: Security: what can you not do with overlays ?
Larry: Cannot represent DoS.
Dick Grunwald: Level 3 that bridges VLANs with MPLS. Why do you need to deploy over NLR ?
Larry: Cost of doing with NLR much smaller than with MPLS.
