Abstract
The Fifth Generation (5G) mobile networking coupled with Internet of Things (IoT) can provide innovative solutions for a wide range of uses cases. The flexibility of virtualized, softwarized and multi-tenant infrastructures and the high performance promised by 5G technology are key to cope with the deployment of the IoT use cases demanded by various vertical businesses. Such 5G IoT use cases incur challenging Quality of Service (QoS) requirements especially connectivity for millions of IoT devices to achieve massive Machine-Type Communication (mMTC). In addition, network slicing is a key enabling technology in 5G multi-tenant networks to create logical virtualized networks for delivering customised solutions to meet diverse QoS requirements. This work presents a 5G IoT framework with network slicing capabilities able to manage a vast number of heterogeneous IoT network slices dynamically on demand. The proposed solution has been empirically tested and validated in five realistic vertical-oriented IoT use cases. The achieved results demonstrate a excellent stability, isolation and scalability while being able to meet extreme QoS requirements even in the most congested and stressful scenarios.
Highlights
The Fifth Generation (5G) mobile networks allow instantiating multiple concurrent logical systems to meet diverse vertical industry service requirements, over a common underlying softwarized, virtualized and multi-tenant infrastructure
SLICE CONTROL AGENT SOUTHBOUND: FLOW AGENT CAPABILITIES TO ENABLE NETWORK SLICING IN 5G Internet of Things (IoT) NETWORKS AND OPEN vSwitch EXTENSIONS 5G architectures are based on softwarization and virtualization, using software defined networks (SDN) and NFV paradigms as enabling technologies [1], [23]
The results presented in this paper are focused on a specific segment of the 5G data plane, the software data path, which is the segment that provides connectivity between the different VMs of the tenants allocated in the physical hosts of the 5G infrastructure
Summary
The Fifth Generation (5G) mobile networks allow instantiating multiple concurrent logical systems to meet diverse vertical industry service requirements, over a common underlying softwarized, virtualized and multi-tenant infrastructure. Industrial IoT services, e.g. mission critical services, can be moved to the Edge of the network in a specific slice to minimize transition delay while massive IoT services e.g. for smart cities will require vast number of dedicated slices, each one with different QoS needs. To the best of the author’s knowledge, the solutions identified in the current literature provide either partial solutions for specific use cases or present preliminary outcomes They have not been validated in a realistic 5G IoT scenario where different services with varying QoS requirements and traffic profile are demanded, challenging the 5G infrastructure and imposing the imperative of addressing 5G network traffic with multiple levels of nested encapsulation.
