Cross-layer Multiuser Session Control for Improved SDN Cloud Communications
Helber Silva, Felipe Barbalho, Augusto Neto · 2018 International Conference on Computing, Networking and Communications (ICNC) · 2018
The integration of Cloud Computing and Internet of Things (IoT) is foreseen as an enabler to suit a plethora of novel latency critical applications (e.g, e-health, intelligent transportation, safety, energy, smart cities, and many others). These applications require multimedia (mainly video) flows to be handled by the underlying network in an efficient and scalable way, as they expect to consume a massive data produced by billions of things. In view of this, we propose a dynamic multiuser session control plane which leverages 5G's support of Software-Defined Networking (SDN) substrate to advance beyond todays limited, per-flow IP-based communication systems. We handle such limitations by proposing CLASSICO, a Cross-LAyer Sdn SessIon COntrol architecture that exploits SDN to offload the flow streaming computation operations from the IoT cloud platform to the network edge, affording high timeliness and scalability for the IoT-cloudified system. CLASSICO dynamically builds Application Layer multiuser data sessions and maps them into enhanced group-enabled data paths featuring SDN replication at branching nodes. We applied our solution to multimedia-alike use case, and results show that CLASSICO outperforms typical SDN-enabled IoT systems in terms to Quality of Service (QoS) and Quality of Experience (QoE) video metrics.
