With the achievement of this field trial, the IPTN solution shows that we can reduce the operational costs and decrease the delay in provisioning of new services in the IP layer as well as in the optical transport layer.
He added : 'OpenFlow and OF-config hold great promise in enabling a logically centralized network controller to subsume more and more of the embedded control plane and vendor-distinct management system functions; however, it may be a couple years before a carrier-grade WAN can be fully OpenFlow-controlled at the packet layer, and it is likely that the optical transport layer will continue to leverage some distributed control plane and/or vendor-distinct management capabilities especially at the photonic layer for the foreseeable future.
This proof-of-concept demonstration shows the potential of Transport SDN, extending the concepts and benefits of SDN to the dynamic optical transport layer.
Unique technology: The network is the first to broadly deploy multi-layer SDN technologies, providing OpenFlow-enabled SDN at both the optical transport layer as well as the packet networking layer.
FLAG has deployed the Infinera DTN in its terrestrial network to provide dense wave division multiplexing (DWDM) and intelligent digital bandwidth management in the optical transport layer.
The capability of switching a Gig E path within the optical transport layer and maintaining the path throughout the entire network and assuring it with a Service Level Agreement (SLA) makes it ideal for wholesale interconnect services.
The optical transport layer provides the basic light-based transmission systems that carry higher-level services such as Internet Protocol and Voice over IP.
The Vx7's VersiColor(TM) wavelength selectable switch, dynamic gain control, rapid transient response, all optical backplane, and tunable lasers enables the industry's first fully automated optical transport layer that enables simple, one-time node engineering with a modular, pay-as-you-grow architecture to ensure low first-in costs.
