9 Example OTT Platform operated in Distributed Cloud OTT wants to offer platform (API) with global support for a fancy new application E.g. CRUD application modules near a given location Provides scalability for API provider Provides better QoE for API consumers Platform operated in distributed cloud (or edge) computing environment Platform implemented in VNFs Resource requirements of platform depend on location, time of day/week and local events Tier 1 Platform in VNF Local IPX Platform in VNF Local NFV orchestration NFV and Connectivity orchestration Platform in VNF Tier Local 3 Platform Tier 2 in VNF Local Tier 3 Tier 2 Platform in VNF Tier Local 3 Platform in VNF Tier 3 Local OTT Platform in VNF Local 5GEx Customers Towards a Distributed Cloud Public Ericsson AB Page 9

13 Distributed Cloud in 5G: Reasons for change Virtualized RAN New functional split allows some RAN functions to run on run in a virtualized environment Flexible scalability and elasticity to minimize permanent peak rate dimensioning New deployment models Gives control to operator to support various deployment models, e.g. centralized or distributed Support co-location of RAN and Core function Potential to provide added value services for third party applications Modular design Current DUs capacity underutilized for many deployments Modular design allows investing where it makes sense Use of merchant silicon Reprogrammable hardware allows repurposing of earlier investments instead of throwing them out LEAP Overview Ericsson Confidential Page 13

18 5GEx in 5G Key Characteristics High diversity types of communication services; Separation of concerns data / control/ management / service Embedded native softwarization in all planes Transition form network of entities to network of (virtual) functions / capabilities ; On demand composition of network functions and network capabilities; Automation in all network segments, network components, network elements, network and resource slices. 5GEx 1st Review: Overview Sept 20,

19 Innovation in 5GEx A technical and business solution for multi-domain service orchestration and provisioning, inclusive of service discovery, bilateral negotiation and service assurance. The solution leverages the NFV architectural model and a new composite (computing and connectivity) crossdomain resource slicing Towards a Distributed Cloud Public Ericsson AB Page 19 A set of APIs enabling service catalogue publishing/sharing, rapid provisioning and large scale invocation of composite services across multiple autonomous systems. The APIs map to reference points in the NFV MANO stack, and extend NFV services into multi-actor wholesale service offerings A live sandbox interconnecting five leading European operators, enabling automated end-to-end orchestration of multiparty 5G services to undergo accelerated prototyping and piloting prior to market launch. The 5GEx sandbox will be evolved and become a living in-operation lab after the project end
