Key Enablers for Next Generation DWDM
Tunable Network—An optical network where optical channels can be moved and changed to different wavelengths completely via software
Omnidirectional—The ability to have a fixed fiber port interface directed to any of the degrees within the ROADM node
Colorless—Applies to lasers, multiplexers, demultiplexers, and receivers. It is the ability to change the wavelength aspects of these devices without moving any physical fibers

Reconfigurable OADM (R-OADM)
Total flexibility—drop an λanywhere, anytime
ROADM provides operational simplicity
No network reengineering for system growth
Nodes scalable from one to 32–40 wavelengths; efficient linear and DWDM rings
Increased service velocity—no need to visit intermediate sites (OpEx)
Low-cost pass-through of wavelength that do not need to drop at a site (CapEx)
Scaleable technology and wavelength path provisioning

Omnidirectional—Network Flexibility
Another flexibility point in the network is directionality
Directionality is the ability, in software, to redirect a channel local to a mesh node to any of the multi-degree directions
Leverage the mesh node for both degree termination and flexible add/drop

ASONASON is the control plane for SDH (HO, LO, Section), PDH (Path, Section) and OTN (Digital & Optical Path, Digital & Optical Section) layer networks.
Typically limited to legacy aggregation only
Other clients (e.g. Ethernet) can be supported through an Adaptation Function.
Acceptable for (low-speed) TDM traffic, may be a client layer for legacy TDM NEs on a newer Optical Control Plane.
Can‘t work for DWDM (no impairment aware)

GMPLS w/ Advanced Optical Control Plane
1. Request connection from A to C by optical user (via EMS) orIP user (via CLI), specifying:
Ports at both ends (optional)Route diversely from a set of links (subnets)Route the same way as another link (part of link bundle add/remove?)
2. The network will find ports at A & C as well as an optical path that respects these SRLG constraints
3. The network will then set up that path end to end
