ONAP Orchestration for Multi-Access Edge Cloud

Mesut Soyturk, Madhu KashyapNETSIA

Agenda

• Why Multi-Access Edge Cloud?• Orchestration as a key control point• ONAP orchestration for Multi-Access Edge Cloud• Future Direction …

Broadband - the infrastructure for the digital society

Sample countries with National Broadband

initiatives

1 Billion users on 5G by 2023

~ 1Billion FTTH users by 2022

Globally, IP traffic (consumer & business, mobile & fixed) will reach 278.1 Exabytes per month in 2021, up from 96.1 Exabytes per month in 2016.- Cisco VNI, Sep. 2018

Global Orchestrator

Multi-Access Cloud for the Edge

• Cost savings by creating a single MANO domain for wired and wireless in the access network

• Increased velocity of new service roll-outs• Example: ONF COMAC

• Disaggregate all mobile and broadband components• Common data plane and control plane

• UPF & BNG

Initial PoC with OSAM

• Seba is fully container based – ONAP cannot onboard• The decision is made to have SEBA represented as a simple PNF to ONAP• 5G was the only use case that was using PNF approach• We based OSAM architecture on 5G

• SDN-R is an approved ONAP project as subproject to ONAP SDNC. The SDN-R project enhances SDNC by adding functions for wireless technologies.

• Exploring SDN-F (Fixed Broadband) for PON (Passive Optical Network)
