Span-Restorable Mesh Networks with Multiple Quality of Protection (QoP) Service Classes

Span-Restorable Mesh Networks with Multiple Quality of Protection (QoP) Service Classes In the modern business environment there is considerable interest in being able to support a range of different transport service classes in an optical network, and charge accordingly. In this work we consider the capacity design problem for a mesh-restorable optical network supporting any mixture of four basic “quality of protection” (QoP) classes. The service definitions are (gold): assured restorability, (silver): best efforts, (bronze): non-protected and (economy): preemptible service. We give design models for optimal capacity design of span-restorable (or corresponding link-protected) mesh networks having any particular mixture of these service classes. We also apply and test the design models under several multi-QoP test case scenarios to gain insights about various strategies and options possible in a multi-QoP design environment. An interesting finding is that in some test cases, 15 to 30% of all demand can be in the gold class enjoying 100% restorability solely through preemption of economy class service capacity. This suggests the potential to design and operate mesh-based networks that have no spare capacity at all in the conventional sense: all capacity is bearing service of some paying type. The resulting frequency of preemption in the economy class services is also studied. Results also show typically high levels of best-efforts restorability in the silver class occurring in networks that are strictly designed only for the restorability of the gold class services. High restorability of best effort services, however, requires the preemption of economy services. These methods and findings can be used by network and business planners to evaluate a number of different service structuring, pricing, and capacity-design strategies that may offer advantages to them and new options for their customers. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Photonic Network Communications Springer Journals

Abstract

In the modern business environment there is considerable interest in being able to support a range of different transport service classes in an optical network, and charge accordingly. In this work we consider the capacity design problem for a mesh-restorable optical network supporting any mixture of four basic “quality of protection” (QoP) classes. The service definitions are (gold): assured restorability, (silver): best efforts, (bronze): non-protected and (economy): preemptible service. We give design models for optimal capacity design of span-restorable (or corresponding link-protected) mesh networks having any particular mixture of these service classes. We also apply and test the design models under several multi-QoP test case scenarios to gain insights about various strategies and options possible in a multi-QoP design environment. An interesting finding is that in some test cases, 15 to 30% of all demand can be in the gold class enjoying 100% restorability solely through preemption of economy class service capacity. This suggests the potential to design and operate mesh-based networks that have no spare capacity at all in the conventional sense: all capacity is bearing service of some paying type. The resulting frequency of preemption in the economy class services is also studied. Results also show typically high levels of best-efforts restorability in the silver class occurring in networks that are strictly designed only for the restorability of the gold class services. High restorability of best effort services, however, requires the preemption of economy services. These methods and findings can be used by network and business planners to evaluate a number of different service structuring, pricing, and capacity-design strategies that may offer advantages to them and new options for their customers.
