Evaluation of Virtualization Models for Optical Connectivity Service Providers
In the SDN architecture, the control and data planes are decoupled, network intelligence and state are logically centralized, and the underlying
network infrastructure is abstracted from the applications.
• SDN is an architectural framework for creating intelligent networks that are programmable, application aware, and more open.
• SDN allows the network to transform into a more effective business enabler.
• SDN enables applications to request and manipulate services provided by the network and allows the network to expose network state back to the applications.
• A key aspect to the architectural framework is the separation of forwarding from control plane, and establishment of standard protocols and abstractions
• To be exposed as tunability constraints to client layer for packet-optical integration (where packet routers connects optically to the colorless ROADM of optical network)
• Lambda selection group (LSG)
• Transponder tunable range constraint, network degree
• Edge binding constraint (EBC)
• Array of { transponder ID, lambda selection group }
• To be exposed as generic mutual exclusivity to client layer
• Resource grouping constraints (RGC)
• Representation of shared resource exclusion between groups of transponders; may be identified by the ID of their connected multiplexers or ROADMs
• To be exposed to virtual networks as resource sharing constraints
Virtualization facilitated by Network Hypervisor and commercial control plane.
