Availability and Cost Based Evaluation of Demand-wise Shared Protection

چکیده
In this paper, we investigate the connection availabilities for the new protection scheme Demand-wise Shared Protection (DSP) and describe an appropriate approach for their computation. The exemplary case study on two realistic network scenarios shows that in most cases the availabilities for DSP are comparable with that for 1+1 path protection and better than in case of shared path protection.

Demand-wise Shared Protection revisited: A new model for survivable network design∗
In this article, a new integer linear programming model for the end-to-end survivability concept Demand-wise Shared Protection (dsp) is presented. dsp is based on the idea that backup capacity is dedicated to a particular demand, but shared within a demand. It combines advantages of dedicated and shared protection: It is more cost-efficient than dedicated protection and operationally easier tha...

متن کاملAvailability-driven optimal design of shared path protection in WDM networks
Availability, defined as the fraction of time a network service is operative, is a key network service parameter. Dedicated protection increases availability but also the cost. Shared protection instead decreases the cost, but also the availability. In this article, we formulate and solve an integer linear programming (ILP) model for the problem of minimizing the backup resources required by a ...
