1
Interoute in Brief
 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
2
i-21 network
 13,500 km duct
 18,000 km fibre
 48 fibre pairs
 80 lamda
 10 Gbit/s
 45 PoPs
 9 countries
 9 MANs
3
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.
4
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

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

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.

Ethernet Service Delivery
•
Deploying Ethernet as an Access Medium
•Adaptation may occur within the MSP
•Granular medium ranging from 2Mb to 1Gbps
•Eliminates costly WAN CPE/CO Upgrades
•Scalable from day one
•Maintain Interoperability with Core

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.

What is VPN?
 provisioning and management of circuits and resources
 partitioned sub network of a larger transmission network
 Read Only: view their existing circuits (alarms, IS, OOS etc)
 Restricted: access to physical ports and bandwidth in contract
 Standard: same as restricted except bandwidth up to port size
 Enhanced:
minimum bandwidth usage
access to physical ports
additional access to “Freepool”
unrestricted bandwidth.
11
What is BOnD?
 similar to VPN except controlled by equipment
 utilises 1355BOnD equipment (OIF – UNI 1.0 compliant)
 requires UNI capable equipment

Layer 1 OVPN – Benefits
 Reducing OPEX
 Automating and speeding-up the Optical Service delivery
 Reducing CAPEX
 Increasing Transport Network capacity utilization through sharing resources
 Ability to set up and tear down circuits in SDH network using a
normal PC with OVPN software.
 Performance Monitoring
 Fault management
14
Commercial
 Lease vs buy ?
 Lease only
 Lease then buy
 Buy dark fibre
 Buy lit fibre
 Bandwidth On Demand
