Presentation Outline

Interoute – In Brief

Research networks - current model

The future challenge - flexible networking

Technology

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

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

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

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

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

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.

L2/L3 NetworkNext 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!

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 usageaccess to physical portsadditional access to “Freepool”unrestricted bandwidth.

13

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.
