Are End-to-End Dynamic Circuits really practical?

I need my TeraBytes here Dynamic circuits? I need my TeraBytes here

I need my TeraBytes here Dynamic circuits? Here is your pipe! Here is your pipe! I need my TeraBytes here

I need my TeraBytes here Dynamic circuits? Here is your pipe! Here is your pipe! I need my TeraBytes here but...

Dynamic circuits? but... .... Here is your pipe! Here is your pipe! I need my TeraBytes here but... Have you set up the routing? Have you opened the firewall? Give me one week to call the maintenance window! How many circuits did you say?!? .... How do I debug it?

What's going on out there?

Social networking

Can't we do the same? Are you connected to CERN? Yes! Let's peer there Are you also at Starlight? Yes! Let's get redundancy there

Bandwidth on Demand? Yes please!

Bandwidth on Demand How fast? Choose your size! I need my TeraBytes here. Now!

No problem: business as usual! No problem: business as usual! Bandwidth on Demand How fast? Choose your size! I need my TeraBytes here. Now! No problem: business as usual! No problem: business as usual!

In practice:

Proof of Concept: the LHCOPN - Traffic between any pairs of connected sites - Effective use of expensive circuits - Dynamic bandwidth allocation on transatlantic circuits

What's next? Distributed IXP* for the LHC Tier centre Tier centre Tier0 Tier centre Access switch in US Access switch in EU Access switch at CERN LHCOPN meeting - Vancouver, September 2009 *IXP = Internet eXchange Point

Opinions?
