1. Don McAuley Senior Optical Pre-Sales Engineer Interoute Barnard’s Inn London R ESEARCH N ETWORKING FROM AN O PERATOR’S PERSPECTIVE

2. 1 Presentation Outline Interoute – In Brief Research networks - current model The future challenge - flexible networking Technology Commercial

3. 2 Founded in 1995 Interoute built and owns the “i-21” network, the largest, most homogenous, latest technology, fiber-optic network in Europe Established European Telecommunications Operator European based with European shareholders Committed investors, fully-funded § Sandoz is majority shareholder § Alcatel has provided vendor financing § No other debt Interoute in Brief

4. 3 13,500 km duct 18,000 km fibre 48 fibre pairs 80 lamda 10 Gbit/s 45 PoPs 9 countries 9 MANs i-21 network

5. 4 Current Model Networks for Research § University campus, school network, research institute etc. § Connection via NRENs § GÉANT (CAESAR, EUMEDCONNECT etc.) Project Specific Networks § Research on networking Test-beds, validation, IPv6, (G)MPLS, etc. § Other research HGP, EGSO, DATATAG, GRIDSTART, etc.

6. 5 The Future Challenge How to get cost-effective, flexible bandwidth to support the daily requirements of researchers How to get it at the same time (and preferably on the same infrastructure) Provide for the needs of an increasing number of bandwidth hungry projects Maintain control and develop the ability to re-charge end users

7. 6 Technology Current § Fixed, point-to-point § E1 – STM-64 § 2.5 Gbit/s wavelengths § 10 Gbit/s wavelengths Future § Ethernet over SDH § 2.5Gbit/s wavelengths § 10Gbit/s wavelengths § Bandwidth On Demand (BOnD) § Customer Web Access & Control

8. 7 Ethernet over SDH Common platform to carry TDM and Ethernet services Use of SDH end to end performance monitoring with guaranteed QoS for both TDM and Data traffic. Full fault management SDH resiliency <50 ms switching time for both data and TDM traffic End to End management, provisioning and billing

9. 8 Ethernet over SDH Ethernet frame mapped in SDH VC-12, VC-3, VC-4 SDH level protection SDH ring/Network Ethernet frame de-mapped from SDH VC-12, VC-3, VC-4 The optical Ethernet ISA boards are present only at each terminating node.

10. 9 10/100 10/100Mb 1Gb GE ADM L2/L3 Network Next Generation SDH Deploying Ethernet as an Access Medium Granular medium ranging from 2Mb to 1Gbps Eliminates costly WAN CPE/CO Upgrades Scalable from day one Adaptation may occur within the MSP Maintain Interoperability with Core CPE Model simplified 2 Port Ethernet L2/L3 device IP Forwarding Ethernet Service Delivery Interoperates with existing SDH network Proven and Reliable technology Installed just about everywhere! MSP DS1/DS3/TDM

11. 10 Wavelength Services Meet the needs of customers who seek the benefits of dark fibre without the associated capital investment Protocol transparent wavelengths at speeds of 2.5Gbps and 10Gbps. ODF CUSTOMER ODF DWDM Traffic Node DWDM ODF Traffic Node CUSTOMER ODF

12. 11 What is VPN? l provisioning and management of circuits and resources l partitioned sub network of a larger transmission network l Read Only: view their existing circuits (alarms, IS, OOS etc) l Restricted: access to physical ports and bandwidth in contract l Standard: same as restricted except bandwidth up to port size l Enhanced: minimum bandwidth usage access to physical ports additional access to “Freepool” unrestricted bandwidth.

13. 12 What is BOnD? l similar to VPN except controlled by equipment l utilises 1355BOnD equipment (OIF – UNI 1.0 compliant) l requires UNI capable equipment
