Conclusions from the LHCONE meeting in Berkeley

From Edoardo:

At the last LHCONE meeting held in Berkeley two weeks ago, important
progress were made on several matters.
 
It has been agreed to progress with the implementation of the LHCONE has
a Layer3 VPN (Virtual Private Network), made by the interconnections of
few VRF (Virtual Routing and  Forwarding) instances provided by R&E
network providers. The VRF suppliers will provide access points to
connect to the T1/2/3 and the necessary bandwidth to interconnect the
access points and the VRFs.
Currently Esnet, Internet2, Geant (and the European NRENs), USLHCnet,
Nordunet, Surfnet, ASGC and CERN have already started to build their own
instances of VRFs and they are agreeing on the interconnections.
 
At the same time, four study groups have been launched to evaluate new
technologies which can be used for the next version of the LHCONE, which
is planned for 2013.
 
Concerning the LHCONE VRF:
 
The LHCONE VRF service will allow to interconnect T1/2/3s in a private
environment: only LHC data will be transprted. Since all the connected
sites will be adhering to the WLCG MoU, LHCONE traffic  may be allowed
to bypass statefull firewalls.
 
A BGP capable router and a public Autonoums System number (ASn) are the
recommended tool-kit to connect to the LHCONE; however small sites can
take advantage of aggregation routers which will be made available by
some VRFs.
 
A set of BGP communities will be made available to allow each site
endowed with a public ASn to set its preferred routing policies in any VRFs.
 
The Shared-VLAN service, aka VLANs 2000 and 3000, has been discontinued.
IP addresses obtained for this service must be returned.
 
More technical information is being added to the LHCONE twiki:
