4. 5G-MoNArch Innovations (II)

5. Functional Innovation: Resource Elasticity
Elasticity: ability to gracefully adapt to load changes in an automatic manner such that at each point in time the available resources match the demand as closely and efficiently as possible.
Dimensions of elasticity: i) computational, ii) orchestration-driven, iii) slice-aware.

6. VNF Elasticity
Three key contributions of resource elasticity functional innovation:
Introduce elasticity at both edge and central cloud taking into account the associated constraints of the cloud infrastructure and the mobile network
Consider that in 5G cloud resources are shared by different slices and their availability may change according to the dynamic request of tenants
Provide an edge cloud architecture where computational and storage resources can be federated, assigned, and scaled where needed according to the load

7. Artificial Intelligence
An AI engine provides the following:
ability to automate network configuration and monitoring processes to reduce OPEX
understanding the configuration and context, such as the dynamic demand of the resources, and the varying service requirements.
taking actions and automating complex human-dependent decision-making processes
ensuring that automated decisions taken by the system are correct
finding bottlenecks of service or failure of network
rapidly reacting to faults to recover
