Blueprint Overview

Introduction & Purpose of EALTEdge

Enterprise Application on Lightweight 5G Telco Edge is a blueprint under 5G/MEC system blueprint family. It intends to provide a edge computing platform along with application orchestration & management to host enterprise applications on lightweight 5G Telco Edge. Provided edge computing platform and management is meant to be implemented in reference to ETSI MEC (please refer ETSI MEC for further details - https://www.etsi.org/technologies/multi-access-edge-computing) For details kindly refer "Targeted Architecture section". BP also intend to provide platform for enterprise application developers to develop, test, package & onboard their applications easily & quickly, thereby empowering developers to innovate & ship faster. Also eventually BP aims to provide platform capabilities and features like Multi-Tenancy, Network-Isolation, Dynamic Orchestration, Network Capabilities exposure, enhanced identification etc. as needed for "MEC in an Enterprise Setting"

...

The edge computing platform(s) (MEP) needs to be installed at the telco edge(s) and Application development/management related components (MECM (MEO+MEPM+Edge Connector), AppStore, Developer Platform) needs to be installed in Telco's cloud (private/public). Edge computing platform (MEP) provides a platform as a service environment for running "Enterprise Applications" In order to be useful, BP requires 5G RAN & UPF to enable connectivity & have configurations based on use case need. Also 5Gc and OSS system needs to be in place with desired configurations.

Use Case

Diverse types of applications in various enterprise sectors, not limited to below:

...

Use Case 1 

Use Case 2

Use Case 3

Architecture

Targeted architecture

Center Node (Located at Telco Cloud)

...

By leveraging upstream projects like EdgeGallery and In collaboration with other BP in same family "5G MEC/Slice System to Support Cloud Gaming, HD Video and Live Broadcasting" (5G MEC/Slice System to Support Cloud Gaming, HD Video and Live Broadcasting Blueprint - Tentative roadmap of integration other BP is Q2 2022), this BP intends to deliver targeted architecture.. 

SDO Compliance/Reference

ETSI MEC

BP leverages EdgeGallery as an upstream which follows the reference architecture as defined in "section 6 Reference architecture" of "https://www.etsi.org/deliver/etsi_gs/MEC/001_099/003/02.01.01_60/gs_mec003v020101p.pdf". Following are components which are available/planned

...

EALTEdge BP will leverage other BP in same BP family "5G MEC/Slice System to Support Cloud Gaming, HD Video and Live Broadcasting Blueprint" for dynamic Traffic routing & steering. Kindly refer that BP for any related SDO references/compliance.

Release 5 Architecture

In this release, BP has been upgrade from EdgeGallery version 0.9 to version 1.1. Also have enhanced Smart shelf in retail sample application.

...

1. In release 5 to use BP, Either
   1.  UPF (external entity to this BP) needs to be pre-configured with DNS redirection rules and traffic rules to ensure connectivity.
   2. UPF integration via UPF adaptor for DNS redirection and traffic rules configurations 

SDO Compliance/Reference

ETSI MEC

BP leverages EdgeGallery v1.1 version which deliver implementation referring some part of ETSI MEC reference architecture as defined in "section 6 Reference architecture" of "https://www.etsi.org/deliver/etsi_gs/MEC/001_099/003/02.01.01_60/gs_mec003v020101p.pdf". Following are components which are available as part of release 5

Platform Architecture

The below diagram gives a overall architecture of the Enterprise Application on Lightweight 5G Telco Edge blueprint as given in Release 5. 

...

• aPaaS:
  
  • Object Detection Service: This service can be used by developer app for various Object detection for example Bottle detection and count for Retail store inventory.
• PaaS:
  • Secret Management: Platform services and developer apps can use this service for sensitive info storing like password, cert etc.
  • Cert Management: Platform services and developer apps can use this service for automate certifications management.
  • DB: common DB for applications data 
  • Monitoring: system and apps health monitoring. 
  • CNI: k8s based networking for multi interface support in a POD for SFC scenarios, network policies etc.
• MEP Server:
  • DNS: DNS server and DNS record management service
  • Service Registry: Service registry and discovery, availability notifications
  • AppLCM: applications life cycle management
  • Network Isolation:  Provides separation of control, management and data plan
• API Gateway: Provides secure End points for MEP services as well as producer Applications.
• Edge Portal: Portal for autonomous edges.
