Introduction and Purpose of the PCEI Architecture

Suzy Gu Deepak Kataria

The purpose of Public Cloud Edge Interface (PCEI) Blueprint family is to specify a set of open APIs for Telco Edge Blueprints to expose towards Public Cloud Service Provider instances at the Edge. As Public Cloud Service Providers deploy Edge instances to better serve their end users and applications, Telco Edge deployments offer many opportunities for collaboration by exposing their network capabilities to provide value added services.

Currently the challengers includes:

• How to combine the public cloud management interface with telco orchestration interface?
• How to open more telco abilities to public cloud and support the DevOps?
• How to manage and monitor these different APIs in an efficient ways?
• How to guarantee security such as avoid the DDOS or SQL injection attack to telco core network?
• How best to leverage network capabilities to provide value added services?
• Can public cloud use the same APIs towards multiple telco cloud edge instances

This BP family is trying to resolve these challengers for both telco and hyperscalers.

High level architectural view:

Jane Shen Deepak Kataria

Architecture as following. This BP will bring a new "Enabler" layer as PCEI between the Telco network and public cloud platform on edge. The PCEI layer is responsible for :

• API Gateway & Management
• Authentication
• Policy
• Composition
• Security services
• Discovery
• SDK

In southbound, this layer will encapsulate the core network capabilities, interwork with BSS/OSS/management system from telco operators. We first suggest to deploy this layer on telco's edge hardware resource.

And in northbound, it provides RESTFUL APIs and SDKs to be called and integrated by public clouds. 

Objectives

Suzy Gu Deepak Kataria

provide an end to end deployment with this enable layer between telco and public cloud.
