Performance characterization of signaling traffic in UMTS virtualized network

Virtualization was invented more than thirty years ago to allow expensive resources to be easily shared in different application environments. As sharing resources, reducing cost and deployment time became hence new mobile virtual network operator (MVNO) requirements, the need for virtualization became more important. Many virtual machines running different applications and databases share the same hardware resources. This paper compares the utility of two virtualized MVNO types: data and voice call MVNOs. We first characterize each one by its signaling traffic load. Then, we formulate the response time for each MVNO based on the traffic models and virtual machine CPU allocation and deduces the utility function. The goal is to compare this two types and conclude the best one to be virtualized.
