5 Infinera 500G on a PIC DTN-X solution from Infinera Photonic integrated circuits (PICs) OTN switching core Ease of use and excellent service wrap Supports GÉANT lambda service: 10G and 100G wavelengths GÉANT lambda service can be extended beyond the GÉANT dark fibre footprint with third party wavelengths. 5

6 Juniper MX MX series of IP/MPLS switch/routers from Juniper The Juniper MX can provide a wide array of switched services (based on EoMPLS) Includes MP2MP as well as P2P Optimised for Ethernet Supports 100GE Replaces our T series routers It is also very good at routing and ready for virtualisation 6

7 What does that mean for your institution? High bandwidth connectivity to most of the world s universities and research institutions Access to remote resources Transmitting large or sensitive data sets Collaboration with colleagues in multiple locations International network services available to HEAnet clients Dedicated international connections (L2, L3, VPN) Access to GÉANT testbed for network research International trouble-shooting Content provider peerings 7

8 Case study: MDVPN and XIFI Multi-domain VPN: supports international MPLS VPNs Security and reassurance of a VPN whilst avoiding firewall traffic inspection = trusted Science DMZ Developed by GÉANT + HEAnet + European NRENs Successfully piloted by the Future Internet XIFI project with TSSG/ Waterford Institute of Technology + HEAnet for Federating Future Internet Infrastructures Adopted by HEAnet for provisioning international L2 and L3 VPNs for Irish users as quickly and easily as within Ireland 8

9 MDVPN: BGP-signalling L2VPN, L3VPN MDVPN: BGP-signalling L2VPN, L3VPN ibgp VPNv4, VPNv6, L2VPN Multi-hop ebgp VPNv4, VPNv6, L2VPN BGP-signaled L2VPN and L3VPN label and prefix exchange Multi-hop ebgp VPNv4, VPNv6, L2VPN ibgp labeled-unicast ebgp labeled-unicast ebgp labeled-unicast Multi-domain PE to PE MPLS path MDVPN is now part of the GÉANT product portfolio

10 A scientist project using MD-VPN for production A scientist project using MD-VPN for production A first scientist project FIWARE FIWARE is a project of the European Public-Private- Partnership on Future Internet (FI-PPP) programme 16 sites connected in 12 countries

11 Focus: GÉANT peering service GÉANT connects to over 50 commercial peers at seven IXs in Europe: robust and dense peering mesh Reflects the changing way that R+E users access and collaborate; academic resources increasingly provided commercially Traffic grown threefold from peaks of 30G in 2014 to 100G today 11

12 GÉANT SA7 supporting clouds GÉANT cloud catalogue, 15 providers: IaaS tender: 30 suppliers have expressed interest. NRENs are collaborating on OwnCloud. NRENs are deploying the open source Rendez-Vous (JITSI) web conferencing platform based on webrtc, as spearheaded by RENATER. The Okeanos IaaS platform from GRNET - adoption pilot. Knowledge sharing activity for OpenStack. Cloud Showcases: 12

13 Focus: Peering service + Blackboard GÉANT established a peering at AMS-IX with Blackboard in 2014 Established primarily on behalf of HEAnet clients but benefits all GÉANT users Provides HEAnet with robustness of an additional path to Blackboard as well as reassurance about the quality of the network as every step is managed by GÉANT, AMS-IX or HEAnet 13

14 Focus: GÉANT test-bed service A facility to the European network research community for testing novel network architectures quickly and easily 2,500km dark fibre infrastructure Dynamically provisioned network environments consisting of computational servers, data transport circuits, and switching/forwarding elements. Generic API for researcher control of their test-bed resources Supports SDN and OpenFlow Available for use by Irish network researchers now: contact HEAnet More at: 14

15 GÉANT Testbed Service (GTS) Network testbed concept to test novel idea Testbed Alpha Description VLAN L1 Virtual Machine A A User logs in, and builds a testbed description via a web GUI frontend to their Testbed Control Agent Ethernet Switch B B Virtual Circuit L3 Resource A port p0, p1; Resource B port out1, out2; Adjacency VLAN L2 C X86 Server C Testbed Description Doc fed to RM TCA B/out1==A/p0; Researcher has a brilliant idea TCA Testbed is activated and user controls it via the TCA RM Resource Manager Allocates resources and sets up the testbed control plane

16 Focus: international connectivity High capacity connections dedicated to Europe s R+E users, including: 100G to North America 10G to China International service delivery p2p, VPN requires close collaboration with partners Support for international performance issues/improvements 16

17 Trans-national education Remote campus support (trans-national education) led by Jisc within GÉANT Includes: requirement gathering, working with local NREN to establish or improve connectivity, supporting roll out of services e.g. eduroam. Case study: UK university with plans to build remote campus on Malta. Worked with Maltese NREN to design solution, including procurement of new national connectivity to the site and GÉANT upgrade (delivered) to cater for capacity requirements. End to end service to be provided by Jisc in the UK, entire connection back to the UK provided by R+E networks Now: preparing business case for dedicated connectivity between GÉANT and the Middle East to benefit institutions with collaborations/ partnerships in the region. 17

18 Beyond the network: collaborative activities Joint procurement for cloud services Objective to bring economies of scale to HEAnet clients Work to cost cloud services Network greening HEAnet led work in GÉANT Encourage the improvement of energy efficiency of the GÉANT service delivery chain from core GÉANT services > NRENs > connected institutions Creation of GÉANT Sustainability Policy + Implementation Strategy For more information on all activities available from HEAnet noc@heanet.ie 18

20 New eastern ring IP IP trunks follow traffic not fibre Trunks follow traffic rather than fibre 50G 50G 50G 100G 10G 50G 10G 10G 50G 50G 40G 10G 50G 10G Routing layer OTN allows flexible and rapid reallocation network services PXM cards allow multiple services to terminate on a single DTN-X 100G port Allows for fine-grained allocation of GÉANT trunks IT FR CH DE CZ AT SK HU Transmission layer Express links saves on high cost router interfaces Trunk capacity can be rapidly adjusted without the need to change routers interfaces Optimises for low latency SI HR Removing n x 10G lags ensures that >10G elephant flows are supported. 20

21 Final thoughts HEAnet plays a vital role in furthering the interests of its clients within the GÉANT community HEAnet clients don t just benefit from international bandwidth but bespoke services and support for the particular needs of R+E users Encourage you to think about whether your institution could benefit from: Dedicated connectivity Test-bed access International troubleshooting Environmental best practice Remote campus/overseas partnership connectivity For more: engage with HEAnet: noc@heanet.ie Find out more about GÉANT: 21
