HEAnet Ireland’s National Education and Research Network, CTVR and Catalan’s
i2CAT Demonstrate First-Ever User-Controlled Provisioning of Pure Optical
links On-Demand using Network Virtualization Networks Dynamically
Reconfigure Themselves to Economically Connect Large Data Flows

Dublin, Ireland/Hayward, CA – February 21, 2007 – A consortium of network
innovators proved today that a user, without prior knowledge of a network or
an understanding of how to configure it, could create their own private
optical network on demand, via a web page and Web Services interface.

Additionally, the consortium’s members demonstrated the ability to
automatically detect and re-route large data flows between countries along
more optimal paths to improve customer service and provide greater network
efficiency.

This series of announcements were made today by HEAnet, Ireland’s National
Research and Education Network (NREN); Trinity College Dublin’s Centre for
Telecommunications Value Chain Research (CTVR); Barcelona’s i2CAT, a
non-profit organization that promotes research and innovation for advanced
Internet technology and Glimmerglass, developer of optical switching
solutions at the core of the new optical Internet. 
  
Using User Controlled LightPath (UCLP) software to control two Glimmerglass
Intelligent Optical Switches via a web interface, a HEAnet user created a
Gigabit Ethernet circuit from the i2CAT facility in Barcelona to Trinity
College in Dublin, using a link from GÉANT over a L2 MPLS Virtual Leased
Line network. In this way, the group demonstrated an agile optical Internet
in which users and communities can define and determine network connections
and desired bandwidth on demand as needed.

“This is the first successful demonstration of using optical switches and
UCLPv1.5 software” said Eoin Kenny, project manager, HEAnet.  “It’s
important because, previous to this UCLPv1.5 software had only been used
with traditional SDH/SONET transmission or Ethernet equipment. This
demonstration enabled a user to automatically request an optical link as
part of complete end to end Gigabit Ethernet circuit from i2CAT in Barcelona
to CTVR in Dublin.” 

In addition to i2CAT developing UCLPv1.5 software to control Glimmerglass
all optical switches, CTVR were able to demonstrate how their IP flow
software was able to create on demand pure optical links using UCLP’s Web
Services and the Glimmerglass switches based on detecting IP flows which
were then switched to alternative optical paths. This technique is often
referred to as optical IP switching (OIS).

Optical IP switching is a pioneering technique developed at CTVR that can be
embedded in IP routers. It analyzes and correlates IP packets, and if IP
flows appear with specific characteristics the router establishes an optical
cut-through path between its upstream and downstream neighbors, requesting
the upstream node to place all the packets belonging to the flow into the
new path. The newly generated trail bypasses the IP layer of the router, as
the packets transparently flow from the upstream to the downstream neighbor.

About HEAnet
HEAnet is Ireland’s national education and research network, providing high
quality Internet services to students and staff in Irish Universities,
Institutes of Technology and educational community including primary and
post primary schools. HEAnet today is one of the largest Internet Service
Providers in the country providing high-speed national network with direct
connectivity to other networks in Ireland, Europe the USA and the rest of
the world in the academic and research communities.

About CTVR
The Centre for Telecommunications Value-Chain Research (CTVR) is an Irish
government initiative established in 2004.  It brings together a team of 100
researchers operating in 8 Universities and third level institutes working
on key problems in wireless and optical networking. The centre aims to carve
out an international leadership position in industry-guided research, which
redefines key elements of telecommunications systems, architectures and
networks, and the value chains used to design, build, market and service
them.



About i2CAT
i2CAT is a non-profit Foundation aimed at fostering research and innovation
supporting advanced Internet technology. Based in Barcelona, Spain, i2CAT
promotes deployment of services and wideband applications from private and
public research companies supporting the Catalunya region. The i2CAT model
aims to make Internet research and innovation accessible to the whole of
society through collaboration between the public sector, businesses and
research groups within universities and the educational world.
