Using OpenFlow to extend software-defined networking (SDN) to the optical
layer is a compelling prospect for enterprises seeking to achieve joint
orchestration of information technology (IT) and network resources for cloud
services, to virtualize the network and to more simply manage
interconnections of distributed data centers that require synchronization.
Today's fragmented, specialized management and control approaches are fraught
with proprietary protocols and management systems, limited scalability and
configuration complexities. With an OpenFlow-enabled transport network, an
enterprise could instead engage in a kind of "one-stop shopping" for control
of cloud computing, storage and networking resources - all via one, unified
application programming interface (API). The benefits could include
significantly simplified configuration, management and scaling of larg... (more)
