The 10.000 feet view
• LHCONE should• Interconnect T1/T2/T3• Avoid saturating general-purpose
R&E IP backbone• Give users better connectivity

Short-term Objectives
• Need to urgently identify LHC-related bottlenecks in general-purpose R&E networks – and provide fixes or workarounds
• Make VLAN solution operational
• Evolution of VLAN model• Evolve into a Routed VPN over P2P?• Evolve into L3 service?• …• Many good proposals on the table
• We are dealing with the short-term issue

NORDUnet Focus
• NORDUnet prefer to focus on the long-term architecture for LHCONE
• According to WLCG, reasonable timeline objective for LHCONE is the 2014 LHC startup / restart
• Action• We need to work on the architecture• We need to test new paradigms and tools• Need for urgency, but no need to rush an
implementation

NSI
• Open • NSI is an open community effort
• Framework• It is a Framework for distributed
network services – not simply the next signaling protocol
• Standard• It is now a standard (OGF), and
gaining increasing support and adoption

NSI Roadmap
• NSI Connection Service (CS) • inter-domain, scalable, and secure
• NSI Topology Exchange (DToX)• Dynamic distributed topology exchange.
Required to automated the local maintenance of local topology and to enable scalable global pathfinding.
• NSI Performance Verification (PFVM)• An architecture for automated service
verification and fault localization/remediation
• Common Service Definitions• Enabling interoperable transport services

OGF NSI Working Group
• The OGF NSI WG is an open working group • Comprehensive community participation
• You can get active• If you have ideas you would like to see incorporated• Pick the brain of an active WG member• Join mailing list, lurk and learn, then join the calls…• Contribute – ask, comment, propose…
• Highly active community, standardizing and developing code

The GLIF Automated GOLE WG was initiated in 2010 to provide a global testbed of Open Lightpath Exchanges for the purpose of maturing the dynamic provisioning software, demonstrating the value of GOLEs to emerging network service models, and to develop a set of BCP for these services.

Dynamic GOLE LHC Pilot
• Déjà vu• …but now we have the standards, an
infrastructure, an engaged community, and a vision for dynamic lightpath exchanges
• Proposal• In parallel to the phase-1 effort…• Form a team representing
• A few T1 / T2 / T3• A few key applications• Members of the Dynamic GOLE WG
• Try it out

Issues to be considered
• Capacity • Dynamic GOLE testbed – sufficient for testing
connectivity, but need expansion for serious data
• Getting to the sites• The last-mile problem
• L3 integration• Announcing L3 connections on internal
networks or to applications when dynamic lightpaths are provisioned
• Getting to the applications• Software stack• Do applications (and their users) want to know
about networking?
