  6. 6. NECOS View on Cloud-Network Slicing 11 5G PPP Architecture Working Group View on 5G Architecture (Version 2.0) From network slicing to cloud network slicing LSDC a novel cloud network approach for Edge and Core that extends the virtualization to all the resources in the involved networks and data centers, providing a uniform management with advanced levels of orchestration.
  7. 7. NECOS Approach: Lightweight Slice Defined Cloud (LSDC) • LSDC usage in – abstracting, isolating, orchestrating and separating logical behaviors from the underlying physical network& cloud resources – creation of logically or physically isolated groups of network & service resources and (virtual) network functions configurations – helping adoption and integration of cloud computing in their large networks – supporting edge devices with low computation and storage capacity • LSDC cloud network - Differentiated Factors – The Slice as a Service –- a new deployment model. Grouping of resources managed as a whole, and that can accommodate service components, independent of other slices. – Embedded methods for an optimal allocation of resources to slices in the cloud and networking infrastructure, to respond to the dynamic changes of the various service demands. – A Management and Orchestration approach making use of methods and artificial intelligence techniques in order to tackle with the complexity of large-scale virtualized infrastructure environments – Making reality of the lightweight principle, in terms of small footprint components deployable on large number of small network and cloud devices at the edges of the network 12
