A Bandwidth-Feasibility Algorithm for Reliable Virtual Network Allocation

Currently, the Internet is the main communication medium, however it does not guarantee Quality of Service. To contour this problem, companies establish Service Level Agreements with their Internet Service Providers, including parameters like bandwidth and reliability of the network. This paper presents an algorithm for virtual network allocation in a reliability context, where a feasible bandwidth approach and reliability calculation are used to deploy the virtual network according to the client´s requirement. Simulations using a real network topology show the effectiveness of the algorithm to deploy the virtual network in a scenario of multiple cumulative requests.
