New paradigms of legacy network features over SDN Architecture

The Software Define Networking (SDN) paradigm proposes faster implementations, flexibility, and a simplified network management, resulting very attractive to new carrier deployments. Nevertheless, migrating legacy networks to SDN scenarios has been slowed down. Traditional network features, such as high availability, load balancing, and scalability are constrained by the centralized nature of SDN architecture. This study evaluates legacy network features, applied to an SDN network, analyzing the impact of this evolution on the network performance. For the evaluation, a set of virtual scenarios has been implemented, assessing different network parameters, in order to measure the impact on the network performance.
