Much of the physical infrastructure of a network is built on a static and fixed platform where there’s a one for one correlation between what is physically connected on both ends of the fiber. That model is increasingly being challenged because of costs and complexities associated with running new fiber, underutilized network assets, and evolving multi-vendor networks to work in concert for next generation architectures.
The economic benefits of converging network layers are powerful. Estimates suggest potential 35% to 50% savings in core router network CAPEX by allowing layer 3 to drive the optimization of optical transport networks. Converging network layers also offers up new range of services and revenue opportunities, allowing end users and service providers to dynamically setup optimal paths based on traffic patterns, quality of service level commitments and time of day effects. Today however, this level of optimization is constrained by the inability of the optical transport layer to flexibly respond to the requirements of the packet layer. While new technologies such as CDC ROADMS offer the needed level of flexibility they are not deployed widely enough to support implementation of multi-layer optimization.
This presentation will discuss creative solutions that solves these issues and supports network wide deployment of multi-layer optimization today by implementing a fabric of optical circuit switching at the edges of networks and between network and vendor domain boundaries and network operators can virtualize all of the new and legacy resources in their optical transport networks, providing a pool of network resources that be efficiently utilized dynamically and in some cases reconfigured on demand.
