Orange has initiated transportPCE, an OpenDaylight project related to the control of OTN/WDM transport networks, relatively static by nature. AT&T, Telia and Comcast have joined the initiative since they share the same needs of programmability and openness for transport networks. Several system vendors have also joined the project in order to share their own vision on the way of controlling these networks.
By developing PCE application for OTN/WDM networks based on OpenDaylight, service providers are willing to get a network controller being open, programmable and independent from industrial implementation thanks to common topological and equipment YANG models. This project is a first step towards dynamic and optimized control of multilayer networks.
