US cable firm Comcast today unveiled a scheme that aims to improve the interoperability between optical and IP network layers and so boost compatibility among multiple networks vendors' equipment.
It aims to identify and define a set of common interfaces which will be used to integrate and manage Nortel dense wavelength division multiplexing and Cisco IP equipment.
Such open interfaces, it is hoped, will improve the vendors' ability to interoperate within the same transport infrastructure, making it simpler to combine optical and IP technologies on the same network.
"This collaboration is a natural and much needed step in the evolution of network technology and the interoperability of multi-vendor networks," said Dave Fellows, chief technology officer at Comcast.
Philippe Morin, general manager for optical networks at Nortel, added: " Together with Cisco and Comcast, we plan to support the broader adoption of the common interfaces that result from this initiative.
"This effort will enable the removal of operational barriers that currently exist between IP and optical networks and establish an intelligent, high bandwidth 'service on demand' network capable of delivering any service, over any path - optical or copper - with complete operational simplicity."
