Overview
  • SURFnet a hybrid network
  • Lightpath networking
  • Global networking (GLIF/GOLEs)
  • NetherLight
  • Automation on SURFnet
  • Key themes review

3
SURFnet
  • The National Research Network in the Netherlands
  • 170 connected organizations, 750.000 users
  • Infrastructure services
  • innovation paid for by government
  • cost effective exploitation for higher education
    and research gt SURFnet6

4
SURFnet6
  • Based on SURFnet-owned managed dark fiber - all
    the way to the customers premises
  • Native IPv4, IPv6 and Light Path Provisioning -
    over a single transmission infrastructure
  • IP Network nodes reduced from 20 routed locations
    to 2 routed locations
  • A hybrid optical and packet switching
    infrastructure

Paving the way to a ubiquitous and scalable
Services Grid

SURFnet6 Lightpath service
  • Lightpaths
  • End-to-end transmission path - with fixed
    characteristics
  • L0/1 connections
  • Virtual lambda!
  • Divert high-bandwidth streams from routed core
  • Enable creation of Optical Private Networks (OPN)
  • Turn the network into an integral part of
    scientific instruments
  • Service
  • Reliable
  • User provisioning - on a managed network
  • Automation
  • Rely on control plane technology for the
    mechanics
  • Add extra intelligence at the service layer

What is GLIF
  • Global Lambda Integrated Facility
  • Virtual international organization promoting
    paradigm of lambda networking
  • Collaborative initiative among worldwide NRENs,
    consortia and institutions
  • World-scale Lambda based Laboratory to facilitate
    application and middleware development

15
GLIF organisation
  • Open community
  • Participants, not members
  • GLIF glues together the networks and resources
    of its participants
  • Jointly make lambdas available for use by
    scientists and projects
  • Work together to develop, test and implement new
    lambda networking technologies, middleware and
    applications
  • Exchange information to learn from each other's
    experiences
  • Bring together leading networking engineers and
    users worldwide

16
GOLE Glif Open Lightpath Exchange
  • GLIF Lambdas and GOLEs
  • GOLE GLIF Open Lightpath Exchange
  • Peering point for lightpaths
  • Global model MANLAN, NetherLight, UKLight,
    Starlight, NORDUnet, HK-light,
  • Open? anyone can bring lambdas
  • Lambda owner controls port
  • GOLE owner makes cross connects happen
  • Limitations only in technology
  • Looking for automation
  • Reduces effort, speeds up global service delivery
  • Enables new applications

17
NetherLight Lightpath connections to the
Netherlands
3rd quarter 2005
18
NetherLight technical
  • Centered around Nortels Optical Cross Connect
    HDXc
  • Up to 640 Gbit/s cross connect capability - i.e.
    up to 64 x 10G lambdas!
  • Generic Framing Procedure (GFP-F)
  • Partitionable on port basis for management
    (operator vs. control plane)
  • Currently still manual

DRAC Basic Architecture
  • Interfaces
  • DRAC UNI (web-service/XML)
  • DRAC Provisioning Client (GUI)
  • DRAC Administration Center
  • configuration, provisioning, monitoring
  • AAA external (SURFnets A-Select)
  • DRAC Server Components
  • DRAC Network Resource Broker
  • Bandwidth management
  • Routing intelligence (intra/inter domain)
  • DRAC Nodal Resource Manager
  • Network element abstraction and mediation
    services

21
Interacting with the service
  • Querying DRAC - before a service is established
  • Usable client ports
  • Indication of available bandwidth - calendar with
    extra functions!
  • Scheduling a connection
  • Query ? availability of specific connection
  • cost and other parameters returned
  • Reserve ? confirmation reference, and guarantee
    of parameters
  • Establish ? service is provisioned when establish
    time has come
  • Verifying a service
  • Status request of a reservation (existing,
    parameters)
  • Status request of an existing connection (up,
    down)
  • Performance monitoring
  • Ethernet level for edge-edge connection
  • STS level for interdomain connection

22
Managing the service
  • Access management
  • Groups
  • Policy (resource access limitations for groups)
  • Connections
  • Schedule, change, cancel connection
  • Monitoring
  • State of DRAC-controlled network
  • DRAC service only gt filtering
  • not a replacement for the network management
    system!!
  • Planning view
  • Per link (internal gt network dimensioning)
  • Per port, connections
  • Accounting

Key Themes
  • SURFnet6 as a hybrid network
  • Lightpath as a global service
  • From the campus around the world
  • GOLEs as peering points enabling GLIF
  • Lightpath automation
  • Static today (OPNs) rapidly automating on
    SURFnet
  • Work with Grid community on dynamic and
    inter-domain aspects, and see how far we can go
