Distributed Switching Overview

Intune has created a system that virtualises physical network connectivity across hundreds of kilometres. Intune's system is built using a new way of switching packets over long distances, with an optical Ethernet switch fabric that can forward packets between ports that are many kilometres apart. This dynamic, distributed system delivers a step-change in network efficiency by virtualising connectivity at layers 0-2, creating a pool of non-blocking connectivity that is available to any port.

The system is designed for large carriers and organisations that have demanding connectivity requirements. It brings a step-change in cost and operational efficiency when connecting distributed data centres, content distribution networks and virtualised IT resources across the wide area. It is also uniquely able to extend Software Defined Networks (SDN) over long distances.


Ultimately, Intune's system will transform operators' network into unified computing platforms, where virtualised IT resources are equally accessible from any point. Intune's technology uses tuneable LASERs to switch individual data packets across a long-reach optical backplane, each packet being sent with its own colour of light. It is the first carrier-grade system to use sub-wavelength switching technology, the standardisation of which is being led by France Telecom along with contributions from Verizon, Telefónica, Swisscom,Telstra, Telecom Italia and others within ITU SG-15.
