Questions

Why are Canada, Japan, the Netherlands, the United Kingdom and the United States involved in GLIF?

What can be accomplished on lambdas that cannot be accomplished on "best-effort" networks?

Where does your infrastructure connect?

What's missing? When will we implement a totally functional LambdaGrid?

What do you see as the future of networking?

Questions

Why are Canada, Japan, the Netherlands, the United Kingdom and the United States involved in GLIF?

Community Lobby

National Competitiveness in Research

Acceptance that one size manifestly doesn’t fit all

Capability for Research

You cant do it alone (by definition its an end-2-end thing)

Trust

Initial condition: Random water/ surfactant mixture.

Self-assembly starts.

Rewind and restart from checkpoint.

Lamellar phase: surfactant bilayers between water layers.

Cubic micellar phase, low surfactant density gradient.

NETWORK NETWORK

Future should be digitised and

processed images

Remote Radiographers ?

Remote Patient information

2nd opinion

• Requires ~ Gbit/s flows for remote access

• Will not be possible without scheduled guaranteed net-

services

What can be accomplished on lambdas that cannot be accomplished on "best-effort" networks?

An R&D network is not a production network – you can do “out of the box” things

Certainty of having what you need when you need it (but not scalable today of course) – means research

computing can be planned

Ability to use non standard transport

Fixed latency => “backplane” connections between compute centres => virtual machine rooms

Provide virtual networks a la UCLP, and push management to the users

What's missing? When will we implement a totally functional LambdaGrid?

When NRENS all adopt hybrid networking as the normal business model

o Requirement: irrefutable proof of benefit o Political: national competitiveness, one price for all

issues.. o Financial: proof of cost effectiveness

o Policy:

When we have a common and “standards” based control plane infrastructure – not individual solutions : now is the

time to get together on this one (IMHO)

I have no idea about the last mile issue

SC2004 GLIF Panel Peter Clarke

What do you see as the future of networking

Wrong guy to ask – I think from point of view of future of computationally intensive research where I would say:

We must get to point where network is not seen by researchers as a big barrier which keeps sites disjoint

Must ensure it is understood that research capability is currently inhibited by “traditional” network provision

Must ensure it is understood that one size doesn’t fit all is a good idea

(there is no way research could be carried out if we all took commercial IP connections)

… a possible Network of the Future….

Provides• Normal best effort IP network where appropriate • Extended “virtual LANs” where appropriate • Switched lightpaths where appropriate
