1st OSM Hackfest

Overview

ETSI's Centre for Testing and Interoperability and the OSM community organised the 1st OSM Hackfest on 15-19 January 2018. The event was hosted in ETSI's headquarters in Sophia Antipolis, France and co-located with the Second NFV Plugtests event

Participation to OSM Hackfests is free and open to all.

Scope

The 1st OSM Hackfest concentrated on VNF on-boarding activities covering Day 0/1/2 operations.

It addressed complex descriptor development to leverage the full suite of capabilities offered by OSM Release THREE, from service and resource orchestration to VNF configuration with charm development.

Objectives

• Install OSM and run some examples
• Get familiar with OSM's GUI and CLI
• Create your own VNF and NS descriptors and build packages
• Understand how to deploy NS/VNF with EPA
• Learn how to add dynamic LCM with Day-1 and Day-2 actions with charms
• Basic troubleshooting
  • Special attention to be paid to troubleshoot real cases from co-located NFV Plugtests.

Who attended

• VNF vendors, who want to onboard their VNF in OSM following best practices
• System Integrators, who want to get used with OSM
• Service providers, who want to get first hand operational experience with OSM
• Academia and Universities, who are considering OSM as platform for their research activities in networking

And, of course, participants in 2nd NFV Plugtests who had specific demands of troubleshooting for their VNF descriptors or Infrastructure
