The next generation of cellular networks are expected to support multiple user-oriented services that have various quality of service (QoS) requirements, yet must be serviced by a single infrastructure.

Abstract

The next generation of cellular networks are expected to support multiple user-oriented services that have various quality of service (QoS) requirements, yet must be serviced by a single infrastructure. To achieve this, network virtualization can play an important role by partitioning/slicing a single physical network resource into multiple virtual networks such that each of the slices can support various services independently. The main contribution of this work is an implementation of static and dynamic resource allocation schemes for different slices supporting different services. We use this implementation to study the effects of increasing the number of network slices on the number of optimization trigger events. Moreover, we propose a non-uniform resource sharing agreement (policy) between the participating network slices and investigate how these sharing agreements affect the frequency of optimization trigger events.
