  1. JRA3 - Bandwidth on Demand Mauro Campanella (from a slide set of Afrodite Sevasti)

  2. JRA3 architecture • Two major modules: Inter-Domain manager (IDM) and the Domain manager (DM) with Standardized interfaces • Each domain participating in BoD service provisioning needs to operate an IDM and honor the IDM-DM and IDM-IDM interfaces • the DM can be any existing one (just proxies need to be developed)

  3. Why an Inter-Domain Manager • The effort to provision end-to-end Bandwidth on Demand services in the European scenario requires specific inter-domain collaboration • Splitting intra-domain management functionalities from inter-domain ones in separate modules, allows multi-domain R&D to proceed autonomously and focus on this less standardized area • At the same time it is compatible existing intra-domain managers through wrappers and interfaces, exploiting a modular approach • This effort can provide solid experience for brokering services other than Bandwidth on Demand

  4. IDM multi-domain issues • The IDM is facing faces the following challenges due to its multi-domain scope: • policies and technological choices • a service and network abstraction schema and specification • advance reservation • multi-domain path finding procedure • monitoring • Authentication and Authorization

  5. IDM Prototype implementation • DJ3.3.2 ‘Functional specification of the IDM prototype’ is available on the GEANT2 web • Objectives • to validate design and architectural assumptions • to define potential risk points and bottlenecks • to test IDM reservation procedures and communication schemas • Modular implementation • Web-services’ technology

  6. IDM Prototype testing • A number of test cases • Single request • Multiple requests • Request with multiple reservations • Multiple simultaneous requests • Multiple simultaneous request to the same destination domain • Multi-domain setup • IDM prototype installations in PSNC, GEANT, GRNET, DANTE • Simulated topologies

  7. Intra-domain provisioning • Manual intra-domain configurations and provisioning for the establishment of the intra-domain segments of the end-to-end path • Intra-domain provisioning design to accommodate • Domains that have a G.ASON/GMPLS CP “out of the box” e.g. Generic MPLS Routing Engine (distributed control plane in their Alcatel 1678 MCC OXC) • Domains operated via NMS • Domains that may decide to adopt proprietary Bandwidth Brokers

  8. Technology StitchingNetwork Technology Types • Based on existing NREN technologies • SONET/SDH • Ethernet based: • Native Ethernet • L2 MPLS VPN • DiffServ technologies • PIP • IP MPLS QoS • 14 different interconnection scenarios in total identified

  9. JRA3 BoD Monitoring • JRA3 aims to use existing NRENs' network infrastructure to provide a BoD service, under a single interface • GN2 JRA1 activity aims to use provide ubiquitous access to monitoring information for groups of uses • JRA3 should build the technology-specific measurement tools for end-to-end L1-L2 services and feed them to the JRA1 framework for storage, processing, concatenation and visualization purposes • DJ3.3.3: Report on BoD service monitoring • Requirements for monitoring BoD service instances (lightpaths) • Functional specifications for the components necessary to allow partial and full path monitoring

  10. Monitoring priorities • Technologies: BoD Ethernet circuits over • One EoMPLS/switched Ethernet network • One SDH-based network • Metrics to be monitored, in order of priority • Up/down • Degraded/not degraded • Level of usage (where possible)

  11. Towards a common NIS • Network Information System to serve all Services • JRA3 focuses on SDH and Ethernet topology modeling

  12. Liaison activities, other than I2, Canarie, ESNET • We are (mainly) looking at: • DRAGON (http://cnl.gmu.edu/dragon/) • MUPBED (http://www.ist-mupbed.org), NOBEL (http://www.ist-nobel.org/) • VIOLA (http://www.viola-testbed.de/) • Testbed • ARGON (Allocation and Reservations in Grid-enabled Optical Networks) • HOPI- GLIF • OIF work and latest drafts

  13. JRA3 team • The JRA3 work is a joint effort of the following NRENs & DANTE • CARNET • CESNET • DANTE • FCCN • GARR • GRNET • HEANET • HUNGARNET • PSNC • REDIRIS • RENATER • SURFNET
