Based upon 10 Gbit/s core

Presents Ethernet at exit points:

- Many 100 Mbit/s for long periods times

- Few 1 Gbit/s for long periods-in practice pseudo-persistent for now-Cross bridges when (if) we come to them

- If needed, and for shorter periods, access to full 10 Gbit/s possible

Today:• 2 x 1 Gbit/s in place for RAL CERN Switched through Amsterdam • 500(290) Mbit/s RAL Lancaster

1-Jan 2006• 6 x 1 Gbit/s

Feb 2007 • Requested 10 Gbit/s

HEP Provision Fermilab UCL

1 Gbit/s for foreseeable future

HEP Provision Tier1 Tier2 and Tier2 to elsewhere

Today we have said to UKERNA: ~ 1 Gbit/s between WITHIN a Tier-2 (i.e. between Tier-2 Institutes) ~ 1 Gbit/s aggregate from EACH Tier2 to Tier1

(note: this means 4 Gbit/s into RAL !!!)

Next (up to 2007): Consolidate existing differentiated Tier2 estimations by

Roget Jones & Barney Garret to revisit existing papers Visit Tier2 sites Visit experiment reps

Default is that Tier2 uses production network for now until ~2007 If clear case for dedicated connections for a Tier2 before end 2006 then we

WILL ask for it. BUT to do this is will be essential that someone at Tier2 GUARANTEES to use

the connection we cannot ask and not use. We cannot do this just based upon generalities

Post 2007 – see next slide

SuperJANET5 and Geant-2

Geant-2 Already committed to provided dedicated capacity across GN2 NRENS will be offered a 10+10 Service (10 IP + 10 GE) They plan to do this for Tier1 to CERN

SuperJANET5: Will be fully live by end 2006 Will incorporate pervasive dedicated circuits Who pays ? work ongoing ?

Messages for UK sites: Dedicated circuits can be provided If your site thinks it needs one we should ask for it – but only if you

know you will use it We must present authoritative documents to UKERNA in advance of

SJ5 as and when we know what we need.
