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, Calif. -- 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 (1) Loosely, any online service delivered over the Web. Such usage appears in articles from non-technical sources, but not in IT-oriented publications, because definition #2 below describes the correct use of the term.  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 National Research and Education Network - (NREN) The realisation of an interconnected gigabit computer network devoted to High Performance Computing and Communications.

 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 as needed prn. See prn order. .

"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 Optical IP Switching (OIS), is a novel method of creating transparent optical connections between network nodes using a flow-based approach. An IP flow is a collection of IP packets going from the same source to the same destination: the exchange of IP packets is the mechanism that  (OIS Noun 1.

).

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.
