  1. HOPI / Dynamic Services Update Rick Summerhill, Internet2 Director, Network Research, Architecture, and Technologies Tom Lehman, ISI East Jerry Sobieski, Mid Atlantic Crossroads John Vollbrecht, Internet2 Spring Member Meeting April 24, 2007 Alexandria, VA

  2. Introduction • Dynamic Circuits work • Intra-domain work focuses on Ciena CoreDirectors • Inter-domain work and collaborations with the International Community • Panel • John Vollbrecht - Summary of Overall Status • Tom Lehman - Control Plane discussion and demo • Jerry Sobieski - DRAGON/HOPI status and Workshops

  3. HOPI and Dynamic Circuit Services - Status Summary John Vollbrecht jrv@internet2.edu

  4. Session Structure • Present status of Internet2 Dynamic Circuit Capabilities and collaborations with other infrastructure providers • Demonstrate operation of new DCS services in “prototypical” multidomain environment • Describe a way that RONS, campuses and others can participate in multidomain infrastructure

  5. Status of Internet2 DCS capabilities • Internet2 has two dynamic circuit infrastructures • HOPI - Hybrid Optical/Packet Infrastructure • DCS - Dynamic Circuit Services being deployed • Both are planned to be maintained for different purposes for the intermediate term • Both use control software “DRAGON” that has been developed by the HOPI Testbed Support Center • Adapted by ISI-East to work with Ciena Infrastructure • Both use Infinera/Level3 infrastructure to provide connectivity between Access Points

  6. DCS Infrastructure - status

  7. Global Dynamic Circuit Infrastructure Many organizations are developing Circuit Services - sometimes called Waves or Lambdas • Internet2, ESnet /SDN, NLR, GEANT, CANARIE, JGN2, others Internet2 collaborates with several group managing/describing dynamic circuit services - DCS • DICE [Dante(GEANT), Internet2, CANARIE and Esnet • GLIF [Global Lambda Integrated Facility]

  11. Standards Bodies • OGF Open Grid Forum • IETF (CCAMP) • IEEE (PTB) • OIF (ASON)

  12. Dynamic Circuit Exchange Points • International networks interconnect • Currently Exchange Points provide ability to switch connections from one provider to another • In future the expectation is that these will provide the ability to switch under program control • For Exchange points that do L1 or L2 GLIF has coined the name GOLE • At Exchange points where switching (which may be single interconnection) providers must exchange information that allows interconnection under program control

  13. GOLES listed on GLIF web page • * AMPATH - Miami • * CERN - Geneva • * CzechLight - Prague • * HKOEP - Hong Kong • * KRLight - Daejoen • * MAN LAN - New York • * MoscowLight - Moscow • * NetherLight - Amsterdam • * NGIX-East - Washington D.C. • * NorthernLight - Stockholm • * Pacific Wave (Los Angeles) - Los Angeles • * Pacific Wave (Seattle) - Seattle • * Pacific Wave (Sunnyvale) - Sunnyvale • * StarLight - Chicago • * T-LEX - Tokyo • * UKLight - London

  14. Interernet2 Dynamic Circuit Connectors • HOPI and DCS provide access to Dynamic Circuits in logically identical ways • Access ports allow circuits to be multiplexed over backbone to other access circuits • Access may include control plane interaction • Connector locations are shown on map in previous slide

  15. Global Dynamic Circuits

  16. Specific Projects • Implement basic DRAGON control plane to run on Ciena infrastructure • See demo • Testing of Ethernet paths • Testing with Spirent has been completed, will be documented in next few weeks • Working to test ethernet between different hardware, at 10G and 1G.

  17. Projects • Work with ESnet to create common module that runs with both ESnet and DRAGON to support authentication of users and trust between domain controllers • Authentication, Authorization, Scheduling • Status- • demonstrated interoperability at control level • Demonstrated ability to make Ethernet path that extends through HOPI(dynamic) and ESNet(static) • Expect to be entirely dynamic in next week or so • Plan is to integrate this into DRAGON • Hope to make this code generally available

  18. OSCARS

  19. SC07 protocol demo plans • University of Amsterdam • Plan to collaborate on developing specific capabilities in DRAGON • Will establish permanent connection between HOPI and UvA • Will do SC07 demo together • Token signaling • Topology sharing

  20. Collaborations DICE • “Stitching” project to describe data layer interconnections between segments of a PTP path • Topology exchange • Reviewing schemas GLIF • Collaborating on developing control plane interoperation between domains

  21. DVTS

  22. TeraPaths • TeraPath sites use QoS within site • Between Sites they may create special path for some flows • MPLS path added over IP • Or create dynamic ckt between routers • Looking into how TeraPaths controllers can configure routers to send specific flows over newly created ckt

  23. Issues in finding and authorizing Segments for dynamic interdomain PTP circuits • Networked topology • Topology exchange, path computation • Types of exchange - OSPF/BGP • Grid/ VO approach • Resource allocation that includes computation, storage and networking Implementation approach is to create “InterDomain Contoller” that can participate in either approach

  24. Status Summary • Making progress in developing and deploying core infrastructure • Collaborating with dynamic circuit community on how it will develop • Working to get users / RONS/ Campuses connected to core • Currently we are at the start of an operational global infrastructure • future is being worked out • users and user needs will shape future development

  27. I2 DCS Control Plane Objectives • Multi-Service, Multi-Domain, Multi-Layer, Multi-Vendor Provisioning • Basic capability is the provision of a “circuit” in above environment • In addition, need control plane features for: • AAA • Scheduling • Easy APIs which combine multiple individual control plane actions into an application specific configuration (i.e., application specific topologies)

  28.

  36. VLSR uni-subnet LSR downstream LSR upstream Integration Core Director Domain into the End-to-End Signaling signaling flow uni, tl1 uni, tl1 data flow Ciena Region CD_a CD_z subnet signaling flow • Signaling is performed in contiguous mode. • Single RSVP signaling session (main session) for end-to-end circuit. • Subnet path is created via a separate RSVP-UNI session (subnet session), similar to using SNMP/CLI to create VLAN on an Ethernet switch. • The simplest case: one VLSR covers the whole UNI subnet. • VLSR is both the source and destination UNI clients. • This VLSR is control-plane ‘home VLSR’ for both CD_a and CD_z. • UNI client is implemented as embedded module using KOM-RSVP API.

DRAGON Control PlaneKey Components • Network Aware Resource Broker – NARB • Intradomain listener, Path Computation, Interdomain Routing • Virtual Label Swapping Router – VLSR • Open source protocols running on PC act as GMPLS network element (OSPF-TE, RSVP-TE) • Control PCs participate in protocol exchanges and provisions covered switch according to protocol events (PATH setup, PATH tear down, state query, etc) • Client System Agent – CSA • End system or client software for signaling into network (UNI or peer mode) • Application Specific Topology Builder – ASTB • User Interface and processing which build topologies on behalf of users • Topologies are a user specific configuration of multiple LSPs
