Sažetak:

Communication networks are witnessing the architectural shift, which manifests through employment of the software-defined networking (SDN) and network virtualization paradigms. Seen as key enablers for network evolution towards the fifth generation (5G), SDN relies on a separated control plane with SDN controllers to set up packet forwarding in the underlying network devices, while network virtualization allows creation of multiple virtual networks that run on top of the same infrastructure, but which may offer different network functions and transport options tailored to specific requirements. Network hypervisors support the latter innovation. SDN-based networks with such a virtualization feature call for customized design, which is of a particular importance for the control plane resilience to different failure types. In this talk, main concepts behind SDN and network virtualization will be outlined, followed by recent research efforts of the “Resilient controller and hypervisor placement for future communication networks (RESyST)” project in that area. More specifically, cost aspects introduced by the network hypervisors will be described, different strategies for protecting the control plane from possible failures will be discussed, while also presenting initial results on the control plane availability and cost analysis with respect to these strategies.
