RESEARCH NETWORKING FROM AN OPERATOR’S PERSPECTIVE Don Mc. Auley Senior Optical Pre-Sales Engineer Interoute Barnard’s Inn London

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

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

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

Current Model l Networks for Research § University campus, school network, research institute etc. § Connection via NRENs § GÉANT (CAESAR, EUMEDCONNECT etc. ) l Project Specific Networks § Research on networking • Test-beds, validation, IPv 6, (G)MPLS, etc. § Other research • HGP, EGSO, DATATAG, GRIDSTART, etc. 4

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

Technology l Current § § Fixed, point-to-point E 1 – STM-64 2. 5 Gbit/s wavelengths 10 Gbit/s wavelengths l Future § § § Ethernet over SDH 2. 5 Gbit/s wavelengths 10 Gbit/s wavelengths Bandwidth On Demand (BOn. D) Customer Web Access & Control 6

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

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

Ethernet Service Delivery • Deploying Ethernet as an Access Medium • Adaptation may occur within the MSP • Granular medium ranging from 2 Mb to 1 Gbps • Eliminates costly WAN CPE/CO Upgrades • Scalable from day one • Maintain Interoperability with Core DS 1/DS 3/TDM GE 10/100 Mb 10/100 Mb MSP Next Generation SDH ADM 1 Gb L 2/L 3 Network 10/100 • CPE Model simplified • 2 Port Ethernet L 2/L 3 device • Interoperates with existing SDH network • IP Forwarding • Proven and Reliable technology • Installed just about everywhere! 9

Wavelength Services l Meet the needs of customers who seek the benefits of dark fibre without the associated capital investment l Protocol transparent wavelengths at speeds of 2. 5 Gbps and 10 Gbps. DWDM ODF CUSTOMER ODF Traffic Node 10

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. 11

What is BOn. D? l similar to VPN except controlled by equipment l utilises 1355 BOn. D equipment (OIF – UNI 1. 0 compliant) l requires UNI capable equipment 12

Layer 1 OVPN – Benefits l Reducing OPEX § Automating and speeding-up the Optical Service delivery l Reducing CAPEX § Increasing Transport Network capacity utilization through sharing resources l Ability to set up and tear down circuits in SDH network using a normal PC with OVPN software. l Performance Monitoring l Fault management 14

Commercial l Lease vs buy ? l Lease only l Lease then buy l Buy dark fibre l Buy lit fibre l Bandwidth On Demand 15
