Optimized Constraint-Based Scheduling of OSPF Graceful Restarts for Maintenance Purposes
10 June 2012
In this paper, we focus on the maintenance of the control plane functionalities in IP/MPLS transport networks by capitalizing on the standardized graceful restart mechanisms. The maintenance planning is formulated as a Constraint Satisfaction Optimization Problem (CSOP). In order to provide effective solutions to this problem, we describe, evaluate and compare two different algorithmic approaches.
