OVNES: Demonstrating 5G network slicing overbooking on real deployments

摘要

The network slicing paradigm provides the necessary means to allow vertical segments to seamlessly share the same network infrastructure, while delivering the expected service level agreements (SLAs) to their own customers. However, the concurrent access at shared resources and the huge disparity among different verticals' service requirements opens up new technical challenges that must be addressed. With this demonstration, we showcase the benefits that centralized orchestration operations, such as slice brokerage and resources allocation, can bring to tackle these issues. Our testbed, namely OVNES, implements the network slicing paradigm on real network equipments and discloses the novel concept of 5G Network Slice Broker as an entity in charge of mediating between vertical network slice requests and physical network resources availability.
