WHAT IS 5GASP?

“Accelerating SME’s towards the ‘new world’ of 5G-based Network Applications (NetApps)”

5GASP offers and operates an Open, and Inter-Domain 5G NFV-based Reference (Open5G-NFV) ecosystem of 5G Experimental Facilities.

5GASP platform provides facilities to test and validate NetApps, embracing a fully automated and open DevOps based CI/CD process for developers, which can translate their applications/services into NetApps, taking into consideration vertical-specific requirements.

NetApp (Onboarding)

NetApp Model Approach:

NetApps defined as Helm Charts

-> VNFD/NSD (OSM based)

Prepare the network slice in order

to host the netapp according to the

NEST requirements

The netapp is deployed in the

prepared slice (attached to the UPFs

edge or Core depending on the NSDs)

NETAPP REQUIREMENTS

To gather 5GASP NetApp requirements it is needed:

1. A generic architectural template to be followed by our NetApps in order to better understand their requirementsin terms of data paths, interactions with the 5G system, placement etc. The developers need to place theirservices in the template. The architectural template is given in following Figure

2. Identification of their requirements by expressing them in the form of the Generic Slice Template of GSMA, thusproducing a NEtwork Slice Type (NEST)

3. Provide integration and dependency needs in terms of resources (VNFs, NSDs, VDUs, etc) and APIs (e.g. 3GPP NEF,ETSI SOLs, TMF, etc)

2. Define NetApp characteristics and properties that a NetApp (must,

should, may) have that will later help us to:

- characterize

- 5GASP certified

- and publish a NetAPP to 5GASP NetAppStore

A NETAPP IN THE CONTEXT OF THE 5G SYSTEM

Although there is no specific definition of what a NetApp is, in 5GASP we identified some key characteristics that may define a NetApp in the context of the 5G System.A NetApp in the context of the 5G System is defined as set of services that provide functionality to verticals. The following are some identified characteristics of a NetApp, thusa NetApp:

• Should deliver services to 5G Verticals• May consist of both software and hardware parts.• Must embrace the Service Based Architecture paradigm• Should follow the ETSI NFV model• Software parts should be delivered in a virtualized or containerized manner.• A NetApp may be part of one or more vertical application services.• May be part of one or more slices. The slices may be shared or not.• May expose APIs to be consumed by other service consumers. The exposed APIs should be delivered in an OpenAPI model and may follow the 3GPP recommended APIs for

applications (i.e. 3GPP CAPIF, SEAL)• One or more services of the NetApp may be attached to one or more UPF data paths• Part of it may reside at the UE side. The part of the UE side may interact with a NetApp service that resides within the domain network. The UE part may follow the

definition of the Vertical Application layer client (VAL) of 3GPP• May be part of the 5G Core. In such case, then it must follow the 3GPP standards.• May interact with the 5G System by consuming 5G system APIs if the 5G system allows(e.g. via NEF). When interacting with the 5G System, it must support 3GPP standards.

Such interactions may include location services, QoS management, AF traffic, etc)• May support service continuity, by minimizing service interruption when transferring application context• May have resource and network requirements in terms of hardware, memory, cpu usage, gpu, H/A availability, etc• May have placement requirements (in the edge, region, core, etc), expressed by a network latency KPI when requesting a vertical slice• May consume monitoring and telemetry data from the 5G System. Such data from the 5G System should be consumed by functions like the NWDAF• May interact with the VIM/CIM of the domain, if this is not restricted by the host domain• May interact with the Service or NFV Orchestrator of the domain, if this is not restricted by the host domain• Should follow 3GPP security definitions and recommendations.
