The international keynote speech of Prof. Augusto Neto at the II MOBISLICE workshop, co-located in the IEEE MFV/SDN 2019: “NECOS Project: Vision Towards Deeper Cloud Network Slicing”.
6. NECOS View on Cloud-Network
Slicing

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. 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
