dc.descriptionCurrently, it is hard to imagine our lives without the Internet, where services are accessed and shared by billions of users every day. However, even after many years, the Internet cannot guarantee Quality of Service (QoS) for the main services to current and future clients. To deal with this problem, clients establish Service Level Agreements (SLAs) with their Internet Service Providers (ISPs), including resilience parameters. The Internet is recognized to be resilient enough for many services, but it is still sensitive to failure events that affect the performance of these services. Software Defined Networks (SDNs) together with Virtual Network (VNs) approaches aim to enhance the management, planning and resource usage of networks. When both approaches are mixed together, we have Virtual Software Defined Network (VSDN). However, the allocation of VSDNs considering resilience issues is still an open issue. Within this context, this paper presents an algorithm for VSDN allocation, called Bw-Risk-Ratio, that considers resilience factors, as well as it deploys the VSDN according to QoS parameters defined in the SLA. Experiments using a real network topology show the effectiveness of the algorithm to deploy the VSDN resilient to failure events when compared to existing solutions. (C) 2016 Elsevier B.V.
