  1. TRILL/802.1aq activityLHCOPN and LHCONE Joint MeetingStockholm, SwedenMay 4, 2012 Ronald van der Pol rvdp@sara.nl

  2. TRILL/SPBM • Offer an Ethernet broadcast domain • Shortest path forwarding • Resilience (IS-IS based re-route) • Multipath support • Normal Ethernet framing at ingress and egress • MAC learning at the edges only • TRILL • Ratified IETF standard • 4096 virtual networks • No OAM defined yet • SPBM • Ratified IEEE standard • 16M virtual networks • IEEE 802.1ag OAM support in hardware

  3. TRILL/SPB is Ethernet Domain with:

  4. Applications & Multipath (1/3)

  5. Applications & Multipath (2/3)

  6. Applications & Multipath (3/3)

  7. Next Steps • Assumption: not all LHCONE is going to use the same technology (be it VRF, L2 domain, IDC, NSI, ProtoGeni, Orca, TRILL, SPB, OpenFlow, etc., etc.) • Currently we have L2 domains, p2p links and VRFs • Question: how can we add TRILL/SPB/OpenFlow to the LHCONE ecosystem?

  8. TRILL/SPB in LHCONE Options • Replace p2p link(s) with TRILL/SPB and get + resilience + multipathing • Replace L2 domain with TRILL/SPB and get + no spanning tree + shortest path forwarding + multipathing • TRILL/SPB features can be emulated with OpenFlow • Proposal: take small steps and open mind approach regarding control planes and network abstractions (NSI community, GENI community, OpenStack/Quantum community, …) • Work with these communities on overall E2E design

  9. Proposal • Start OpenFlow based tests to experiment with TRILL/SPB features • Automatic failover after link failure • Shortest path forwarding • Multipath support • Participants: • SURFnet/SARA, USLHCNet, CERN, Internet2 (MANLAN), NORDUnet?Others?
