Model-based approaches for self-diagnosis of telecommunication networks develop reasonings based on formal and explicit representation of network structure and network behavior. Network behavior modeling is a central issue for these methods. In a recent work, we have proposed a model of architecture and fault propagation of the FTTH (Fiber To The Home) access networks based on GPON (Gigabit capable...
Efficient design of networks topologies is challenging, especially with the arrival of the virtualization in these last years. In this paper, we deal with the Capacitated Network Design Problem (CNDP) with modular link capacities to design minimum cost network while satisfying the flow demands. We propose a two levels Genetic Algorithm (GA) based model that can deal with several variations of CNDP...
The aim of this research is to enhance the performance of the Fast Re-Route (FRR) mechanism by adopting a methodology similar in many aspects to that used in Software Defined Networking (SDN). This methodology is represented by using a central controller to calculate the paths of backup MPLS tunnels that are used to protect previously established primary MPLS tunnels, and a messaging system to install...
