  1. Update on OpenNSA LHCONE Meeting, CERN, February 2014 Henrik Thostrup Jensen <htj@nordu.net

  2. NORDUnet at TNC, Reykjavik, May 2012 NORDUnet BoD Service • NSI CSv2 is out for public comments • NORDUnet will offer a BoD production service based on NSI • Initial availability: May-June for something simple, but working • Continued improvements after that

  3. NORDUnet BoD Service • Close cooperation with SURFnet & GEANT • Provide an interoperable service across Europe • AAI & Topology is outside the NSI CS specification, but required for an interoperable service • Common way to describe AAI attributes • Connection traces to identify origin and loop prevention • Topology model based on reachability • Still presents an NML topology for compatibility

  4. Technical Setup • MPLS VPNs • No policing/guaranties/shaping for 1H 2014 • Will be added later • Backbone will be upgrade to 100G this spring • Operational tools is still on the weak side • Have CLI, but a lot of stuff missing • Probably holds for most NSI implementations Juniper OpenNSA NCS Juniper NSI Juniper

  5. Technical Setup • Initial demarcation points • Netherlight • Copenhagen (DeIC/GEANT) • Stockholm (Onsala) • London

  6. OpenNSA • NSA = NSI Agent (no relations to NSA) • Used on ~5 sites outside NORDUnet • UvA, CESNET, iCAIR/Starlight, AMPath, UFRJ • Pluggable backends (ethernet+vlan) • Juniper MX/EX, Force10, Brocade, NCS … • Built-in aggregator • Implements NCS CSv2 (WSDL r117) (mostly) • Python, Twisted, BSD-license • git clone git://git.nordu.net/opennsa.git
