  1. Bram Peeters SURFnet Forskingsnet konference 2005 Middelfart - Danmark November 2, 2005

  2. 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 => 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

  5. SURFnet6 - DWDM on dark fiber

  6. SURFnet6: IP network implementation SURFnet6 Core Routers Avici SSR External IP connectivity Avici SSR Avici SSR Avici SSR 10 GE Nortel OM 5000 10 GE Nortel OME 6500 Nortel OM 5000 Nortel OME 6500 SURFnet6 Common Photonic Layer Nortel OM 5000 Nortel Passport 8600 10 Gigabit Ethernet Customer Nortel OME 6500 1 GE 1 Gigabit Ethernet Customer CPE 10 GE SURFnet infrastructure Non-SURFnet

  7. 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

  14. 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 Nortel’s 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…

  19. Automation of Lightpaths - using DRAC (Nortel’s Dynamic Resource Allocation Controller) “UNI” - Simple interface DRAC Control plane SURFnet6 Nortel OME 6500 Nortel OME 6500 User Nortel OME 6500 CPE Nortel OME 6500 1 GE resource Customer equipment CPE 1 GE Customer equipment Service: End-to-End Light Path SURFnet infrastructure Non-SURFnet

  20. DRAC Basic Architecture Interfaces • “DRAC UNI” (web-service/XML) • DRAC Provisioning Client (GUI) • DRAC Administration Center • configuration, provisioning, monitoring • AAA – external (SURFnet’s 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 • DRAC Light Path Control Plane • Dynamic management of resources within the network. • Server based => also non CP-elements supported

  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 => filtering • not a replacement for the network management system!! • Planning view • Per link (internal => network dimensioning) • Per port, connections • Accounting • Logs of usage

  23. 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
