Title: JRA3 - Bandwidth on Demand

JRA3 - Bandwidth on Demand
GGF16 Athens, 14th February 2006 Afrodite

GN2 project
  • Multi-Gigabit European Academic Network
  • Project funded under FP6 (Research
    Infrastructures-Integrated Infrastructure
    Initiative)
  • 31 partners (NRENs, DANTE, TERENA)
  • Total expected budget 178.643.730
  • EC contribution requested 93.000.000
  • Duration 4 years
  • Combining in a single contract, several
    activities essential to reinforce research
    infrastructures and to provide an integrated
    service at the European level
  • Networking activities (including consortium
    management)
  • Provision of access to transnational users
  • Joint Research Activities
  • Scope
  • Further develops the successful GN1 project which
    has created the GEANT pan-European network
  • Specific emphasis on end-to-end provision of
    services across multiple interconnected networks
  • Gaining improved understanding of user needs
  • Direct support and performance monitoring
  • Migration from IP services to combination of
    routing and switching, network control,
    light-paths

Goals of JRA3 in GN2 project
  • Joint Research Activity
  • aim for a proof-of-concept and pilot network
    service for dedicated capacity provisioning
  • production service during a subsequent project
  • Streamline the inter-domain setup of lightpaths
  • shorten the provisioning time
  • reduce the amount of human intervention
  • Take into account heterogeneity from the
    beginning
  • Specify and document the manual procedures
  • Automate the process step-by-step focus on
    inter-domain coordination process
  • Provide northbound interfaces/APIs to
    applications-middleware

4
Service Definition
  • Point-to-point, connection oriented service
  • Non-contended capacity
  • Layer 1, 2
  • focus on provisioning of a deterministic
    non-contended bandwidth pipe between two 1Gigabit
    Ethernet access ports over multiple domains that
    employ different technologies
  • Multi-domain and multi-technology
  • e.g. SDH with GFP, EoMPLS, native Ethernet
  • Automated provisioning
  • Advance reservation (scheduled)

5
Requirements survey
  • Deliverable DJ3.2.1 GÉANT2 Bandwidth on Demand
    (BoD) User and Application Survey
  • disappointing response rate (6 out of 12)
  • GRID community most responsive
  • The questionnaire was organized as follows
  • General Issues, description of the application
  • Control Issues, requirements on BoD system and
    its interfaces
  • Network Issues, capacity requirements, service
    duration, etc.
  • ReIiability Issues, latency, security,
    restoration, etc.
  • Other Issues, accounting, participation in a BoD
    pilot, etc.
  • RESULTS
  • The need for BoD-like services exists today for a
    (small) number of different communities/projects/u
    sers groups
  • BoD users/applications should be provided with
    standardized interfaces for resource
    reservations and service monitoring
  • Web services approach looks popular
  • Ability to schedule reservations seems important
  • Bandwidth requirements range from 10 Mbps to 10
    Gbps
  • A number of the projects/user groups contacted
    expressed interest in testing a prototype BoD
    system

6
State-of-Art survey
  • Deliverable DJ3.2.2 Initial Review of
    Technologies Related to the Provision of
    Bandwidth-on-Demand (BoD) Services
  • Mainly covers
  • Transmission switching technologies
  • Control Plane technologies
  • BW broker implementations
  • BMP, CATI, DRAC, DRAGON, ODIN, Operax, SBM,
    Tequila, UCLP
  • An update is expected during Y2 including
  • recent developements in the OIF, IETF
  • results of the collaboration with other projects
    related to JRA3 activities (MUPBED, DRAGON,
    VIOLA, HOPI ...)

Multi-domain provisioning
8
Service characteristics
  • Inter-domain the end user points may be located
    in different domains
  • Capacity The minimum amount of capacity that can
    be requested will depend on local domain policies
    and restrictions imposed by the technology used
    (e.g. SDH granularity)
  • Point to point the BoD service provides
    Point-to-Point services. Point-to-Multipoint may
    be realized as a set of point-to-point services
  • Bi-directional the service is a bi-directional
    service
  • Symmetric capacity
  • Symmetric paths
  • Advance reservations
  • Protection

9
Inter Domain Manager
  • A set of automated procedures for the required
    non-technology specific inter-domain negotiations
    in order to establish an end-to-end non-contended
    1 GE bandwidth pipe
  • Reservation process
  • Ensure adequate e2e capacity
  • Ensure technical feasibility (e.g. a common VLAN
    id along the e2e path)
  • Capacity reservation scheduling
  • Path resilience-restoration

10
Intra-domain provisioning
  • Manual intra-domain configurations and
    provisioning processes 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
  • Intra-domain modules, implemented in later
    phases, will comprise the so-called BoD service
    Domain Manager (DM)

11
Integration of technologies
  • Evaluating the implementation implications and
    testing a number or scenarios

12
Monitoring
  • Inter-domain monitoring system must
  • Troubleshoot in case of failure
  • Provide concatenated monitoring data of the
    quality of the end-to-end service
  • Working together with relevant GN2 project
    activities (JRA1 and JRA4)
  • JRA3 will provide technology-specific monitoring
    data at L1-2 as well as topology data
  • JRA1 will provide monitoring data management and
    visualization
  • Activities
  • Design and prototype implementation of the
    database schema and interface for retrieving and
    storing monitoring data from the Alcatel NMS
    (GEANT2 core)
  • Specification and design of the database schema
    and application for retrieving and storing
    monitoring data in EoMPLS and native Ethernet
    topologies
  • Integration of the monitoring data extraction and
    storage components with the JRA3 Network Topology
    Database
  • Minimum requirements for monitoring
  • Initially focus on availability lt up/down
    info, unavailable-seconds
  • Also offered capacity, errors lt BER, error
    counter, errored-seconds

13
Implementation
  • Following the Web-services paradigm
  • Each component of the system is implemented as a
    Web service
  • Interfaces are defined between IDMs, the IDM and
    the DM of a domain, the DM and the technology
    proxy within a domain
  • Using Java, MySQL
  • A prototype of the IDM is expected by May 2006
