  1. HEAnet's Major Network Evolution Andrew Mackarel David Wilson

  2. Agenda National Networking Projects • HEAnet’s IP network • New ROADM Network European Networking Research Projects • AutoBAHN • Manticore & Federica • Questions & Answers

  3. HEAnet’sIP network Current Network Map on the Website

  4. Today Effective limit of old equipment Effective limit of new equipment 5 years Bandwidth Demand

  5. Hardware New IP Network uses Cisco CRS-1s • Scalability • 40 Gbit/s interfaces currently installed • Upgrade to 100Gbit/s interfaces in future => 1.5+ Terabits per second total • Supports current and future services • New operating system platform: IOS-XR designed for future Protocol and Services.

  6. New Features • Top Class solution which allows for future growth • 10Gbit/s connections available now • Scale to 100Gbit/s peer, multi-10Gbit/s per client when required in future • Support for critical new features • High Availability online IOS-XR updates etc • IPv6 multicast • 4 byte ASN • Secure Domain Routing (Virtual Routing)

  7. Collapsed backbone • Best Current Practice: • Model now being followed by many NRENs SURFNET , SUNET Concentrate, then duplicate • Concentrating => • Less hardware, • Less to go wrong, • Easier to scale • Duplicating => • Resilience • Network Consistency • Two routers • One in Citywest, one in Kilcarbery Park

  8. Project Implementation • Late Nov - Acceptance tests • End Nov - HEAnet services transferred • Dec - First clients and peers • Jan-Feb - Next 10 clients • Feb-April - Next 20 Clients • May-Aug - Remaining 25 clients • Technology conversions / connection upgrades

  9. Current Client Status • All Clients transitioned onto New Network • Ethernet Connectivity • allows clients burst up to 10Gbit/s per interface • Provision for Future 10Gbit/s client connections • BGP Peerings • client gets connectivity via NBE to both routers • Primary/backup connections • Resilience now a function of the underlying NBE • BGP changes in previous years paid off – Thanks!!

  10. Current Peering Status 2007 2008 Tiscali Telia

  11. Multi-pop backbone • Overlaid on National Backbone • Dark fibre network provides Ethernet point-to-point capability • Brings networkto the client • Reduces cost • Increases flexibility • Adds resilience • now expanded by NBE Project

  12. HEAnets ROADM Network HEAnets ROADM Network Uses Adva FSP 3000 ROADMs Rev 7 CfT 2008 Fully Compatible with CWDM Network

  13. Why ROADMS in HEAnets network? Why are ROADMS needed ? • More Capacity is needed in Fibre Core Network now • By 2009/2010, UCD, DCU and TCD will all require 10Gbit/s IP links • The aggregate bandwidth (considering p2p and IP links) inside the Dublin Metro Ring will be soon be larger then 10 Gbit/s. • Other Regions are following the same pattern • Other Projects expected to aggravate this Bandwidth problem • e-INIS Project • HPC: ICHEC & other grid clusters or supercomputers • Researchers may also require Point to Point Connections to CERN’s Large Hadron Collider and other projects. Normally 10Gbit/s links.

  14. What is a ROADM? Reconfigurable Optical Add Drop multiplexer • Software configurable DWDM Multiplexer • Flexibility to add/drop/continue wavelengths • Ability to provide 10Gbit/s circuits “on demand” • Uses Combination of new technologies. • Tunable lasers • GMPLS control plane • Fast Evolving Technology Performance and cost reductions continuously => implement only in network where required

  15. ROADM advantages • Network Layout planning is flexible and can be modified quickly. • Allows Backbone capacity expansion without need for additional Fibres • ROADM allows for remote configuration and reconfiguration. • ROADMs allow for automatic power balancing • In a DWDM network , making changes is more complex requires more pre design , provision and power balancing . DWDM Networks => Static Designs ROADMs give more flexibility

  16. HEAnets wavelength service ? • Point to point circuit connectivity • Ethernet Frame format • Offers • No contention • Protection or No Protection • Dublin Metro Ring Dynamic connections Immediately availability with ROADMs • National/International Static Immediately with DWDM Dynamicconnections 2010 availabilitywith ROADMS Contact HEAnet NOC for further Details

  17. HEAnet National Fibre Core Today’s Network ROADMs DWDM Commissioned Oct 2008

  18. Future Network Integration • Development of an API/Web service for access to the GMPLS interface for E-INIS , AutoBAHN projects and others • Implement as a GMPLS Network This will allow • Wavelength based network discovery • Wavelength based end-to-end circuit/path provisioning • Optical Restoration

  19. AutoBAHNBandwidth on Demand

  20. AutoBAHN • a Research activity for engineering, automating and streamlining the inter-domain setup of guaranteed capacity (Gbps) end-to-end paths • Bandwidth on Demand … a Joint Research Activity of the GN2 project • GN2 is an European Commission-funded project, with all the European Research and Education networks (NRENs) as partners

  21. SC 08 Demo 4 Sites simulating Radio Telescopes, 3 in Europe and 1 in the US Data transferred on 4 by 1 Gb BoD links to Software Correlator in Amsterdam

  22. Point to Point path issues • Multiple administrative domains • Multiple data plane technologies • Security

  23. AutoBAHN’s approach • NREN Distributed control and provisioning • Business-layer related interactions include AA, policies, advance reservations etc. • Privacy and control of intra-domain resources must be safeguarded => Definition of a Full Architecture • Inter-Domain Manager (IDM) Provisioning • Domain Manager (DM) Technology Specific • Interfaces Local Provisioning

  24. Current Status • Working Prototype based on GEANT Testbed • 8 participating NRENS locations • HEAnet, PSNC, GRNET, CESNET, • CARNET,DANTE,GARR,FCCN • 2 Working Technology Proxies for full automated Provisioning • HEAnet MPLS/ Ethernet, DANTE SDH • 7 Demos in 2008 • 4 Connectivity based • 3 Application based High Definition Video, SCARI/e • GN3 Implementation across NRENS 2009 – 2013 • Working on standardisation efforts

  25. AutoBAHN is Internet2 compatible Links to US NREN Networks => Transatlantic Point to PointResearch Links

RPSL aut-num: AS1213 as-name: HEANET descr: HEAnet national network import: from AS1299 # Telia [transit provider] action pref=100; accept ANY import: from AS3257 # Tiscali [transit provider] action pref=100; accept ANY import: from AS20965 # GEANT [private peer] action pref=50; accept ANY export: to AS20965 # GEANT announce AS-HEANET export: to AS3257 # Tiscali announce AS-HEANET export: to AS1299 # Telia announce AS-HEANET 5 32

  33. Logical IP Network Service • Define the edge ports of the IP network • Define the external Routing Service(policy) • In case there are preferences on internal transport services, QoS: the internal Routing Service metric • Your IP address pool (guided by your ISP) 6 33

  34. Benefits • On-demand network • Share virtual routers, not buying your own • No self-assembly required 6 34

  40. Example deployment • Two organizations: • NREN A: Physical Network Administrator. In this very simple example it operates a network with one physical router. • i2CAT: Virtual Network Administrator. In this very simple example it will request two logical routers to NREN A. • MANTICORE Software deployment • NREN A Server: • User Workspace WS • Ethernet Resource WS • IP Network WS • Router WS • i2cat Server: • (optional)‏ • User Workspace WS • Ethernet Resource WS • IP Network WS 43 15

  41. When NREN A first launches the GUI client, it must create a new physical network and add all the routers they want to manage to it. 44 16

  42. 45

  43. Create logical interfaces • Create logical routers • Assign i/fs to routers • Create tunnel between the logical routers 46 18

  44. 47

  45. Physical network admin creates “resource list” 48 20

  46. OSPF configuration BGP configuration • i2cat logical admin creates a new IP Network and adds the resources of the resource list to it. • Now he can configure the IP parameters of the interfaces, configure IGPs, configure the peering, ... 50 22
