Key Elements of Agile Photonic Network<br />
Wavelength Selective Switch<br />
• Compact equalisation for Ciena and foreign <br />
• Per routing.<br />
• Experience of building WSS infrastructures<br />
since 2005<br />
Metro Network<br />
Coherent terminals <strong>with</strong> advanced<br />
signal processing and error correction.<br />
• Compensation of per wavelength path.<br />
• Improved performance<br />
• Cost effective spectral efficiency<br />
• Simple operations.<br />
Long Haul<br />
Network<br />
Leverages Moore’s Law<br />
& DSP innovation<br />
through arbitrary<br />
routing of progressive<br />
generations of terminal<br />
across the same<br />
photonic cloud<br />
Distributed, hierarchical photonic control<br />
system (Domain Optical Control)<br />
• Simple digital provisioning on analogue<br />
photonics for Ciena and foreign <br />
• Service continuity through fast control to<br />
suppress transients.<br />
• Enables addition of progressive terminal<br />
generations to installed infrastructure.<br />
• Reports photonic parameters and topology<br />
to <strong>network</strong> <strong>management</strong> to simplify planning<br />

Software Defined Networking<br />
The addition of a software layer to mitigate between the demands of the<br />
services and the available <strong>network</strong> resources in a dynamic environment where<br />
service changes frequently occur due to end-user, operator, or application<br />
requirements.<br />
• The<br />
• The<br />
treatment of traffic tailored on a per service basis (e.g. SLA, latency, bandwidth).<br />
routing of traffic may be designed to optimize the <strong>network</strong> (e.g. power, cost, …)<br />

Software-Driven Networking<br />
Service providers see lengthy tenure of legacy <strong>network</strong>s, especially in core; but want<br />
key benefits of SDN through software<br />
Service providers want & need powerful controllers: virtualization, abstraction for large <strong>network</strong>s<br />
Service providers are looking for an eco-system in software to address their needs<br />
