Demo: A Network Simulator for 5G Virtualized Networks

Current 5G and beyond research explores how to leverage network virtualization, which allows network operators to partition the network into multiple independent slices, each of which can carry multiple types of traffic, to provide flexibility and scalability in the deployment of new network services. In this context, this paper presents the description of a network simulator, that addresses the key related 5G features, i.e., modeling of virtual network functions, network slicing, ability to change some network parameters during run-time, and a more realistic network traffic generation. During the demo, we deploy several slices with different types of traffic to demonstrate that our simulator can support applications like network management and orchestration. The evaluation results show that our simulator is a powerful tool for testing 5G networks.
