Virtual Data Center Networks Embedded as a Service Using Software Defined Networks

Based on Software Defined Network paradigm we apply the Network-as-a-Service model to build a data center network architecture well-suited to the problem of virtual networks embedding. This task is performed by the algorithm proposed in this paper, which is based on aggregated information from a virtual routing plane using the BGP protocol and a physical network topology based on Open Flow 1.3 devices. The experimental evaluation shows that the proposed algorithm performs efficient load balancing on the data center network and altogether yields better utilization of the physical resources.
