Simulations of a Service Velocity Network Employing Regenerator Site Concentration • “The transitions from today’s static networks ( to dynamic photonic networks ), ….., has been stymied by a range of technology and cost issues.” • “Practical ROADM designs …. have been published, and hardware is becoming commercially available, but challenges remain in operational practices and business models.” Page 5 Multi-Layer Awareness and Management (NFOEC)

Simulations of a Service Velocity Network Employing Regenerator Site Concentration • Previous work (JOCN, Feb. 2012): � Service Velocity: Rapid Provisioning Strategies in Optical ROADM Networks � “ For networks to achieve fully dynamic operation, not only technology, but also business models and network operations must evolve. …, a key application driver for CN ROADMs may be the ability to pre-deploy regenerators in support of accelerated connection provisioning in the network. If all needed regenerators are pre-deployed, a new circuit can be remotely provisioned without requiring manual operations at any intermediate nodes, enabling new connections to become operational with minimal delay.” Page 6 Multi-Layer Awareness and Management (NFOEC)

Simulations of a Service Velocity Network Employing Regenerator Site Concentration • Traffic: � Quasi-static � Traffic matrix in which the population of each city determines its probability to be used as a source or destination. • Upgrade: � Adding regenerators when it is needed to sustain future demands. � Overbuild of individual fiber links when they exceed 60% wavelength fill, up to maximum of three fiber pairs per link.

Simulations of a Service Velocity Network Employing Regenerator Site Concentration Results above 900 demands are not plotted as these represent a distorted traffic pattern and an unrealistic mode of operation (above 900 demands, the network operator would be turning away customers whose requests are inconvenient).

Optical network evolving towards smart network in Korea Page 11 Multi-Layer Awareness and Management (NFOEC)

Optical network evolving towards smart network in Korea • Maintaining an efficient fiber management system meeting to the growing needs of fiber cable connection in the access network… • Meeting to the dynamic needs regarding the network management coming from the dynamic convergence service environment… Page 12 Multi-Layer Awareness and Management (NFOEC)

Optical network evolving towards smart network in Korea Video As the smart node is content placed at the nearest edge request in the cell service area, the quality of video service is properly guaranteed. Video content request Delivers the satellite broadcasting channels. RF signals are relayed to customer premise through fiber cable by using a third wavelength dedicated for the video overlay.

Designing Survivable Networks (NFOEC) On Shared Risk Link Group Optimization Guangzhi Li, Dongmei Wang, Timothy Gallivan, and Robert Doverspike AT&T Labs Page 23

On Shared Risk Link Group Optimization • The SRLG Information for each IP-layer link describes a list of SRLGs to which the link belongs. • SRLGs are often represented by IDs in layer planning systems at various network layers (e.g., “bundle” ID). • Some routing protocol enforce a maximum list length of the number of bundle IDs per link. • However, in reality, there are links that exceed the maximum (the number of SRLG IDs could exceed 50,000 IDs easily in a large carrier). • One solution is to combine multiple fiber spans (without bifurcation) to one super fiber span to reduce the number of SRLGs.
