ETSI SUMMIT ONSTANDARDIZATION AND OPEN SOURCE
ETSI ISG NFV AND OPEN SOURCEPresented byMarie‐Paule Odini, ETSI ISG NFV Vice ChairFrank Zdarsky, ETSI ISG NFV Open Source Rapporteur© All rights reserved
ETSI ISG Network Functions VirtualisationNFV = Cloudification of current physical telco network appliances and their management and orchestrationETSI ISG NFV Phase 1 (2013‐2014) focus:creating industry momentum and alignment, architectural framework
ETSI ISG NFV Phase 2 (2015‐2016) focus:fostering interoperability between implementationsroughly follows stage model
Early identification of need for implementer feedbackPoC framework, creation of OPNFV project
2 ETSI Summit on Standards and Open Source – Sophia Antipolis, France, 2015‐11‐19
Open Platform for NFV (OPNFV)Open source, carrier‐grade reference implementation of an NFV platform= NFV Infrastructure & Management
Integrates and extends existingopen source, doesn’t develop own new implementationsOpenStack (cloud), OpenDaylight (SDN), Linux/KVM (virt.), …
Open Source devpt model:rapid iterations

Fostering Interaction between Std. & OSSETSI NFV formed OSS Work Item in TST WGOrganised joint session with multiple OSS projectsdifferent language / culturedifferent methodology / time linedifferent expectations“Here’s the spec, go implement.” vs. “Give requirements, come implement.”
Facilitated information exchangeall draft versions of specs immediately made publicly availablecreated public “issue tracker” to collect feedback from implementers
Joint activities / overlaps of ETSI NFV and OPNFV membersMapping activity of ETSI NFV to Open Source APIs, use cases
ETSI Summit on Standards and Open Source – Sophia Antipolis, France, 2015‐11‐194
Lessons LearnedStandards and Open Source are complementaryETSI NFV: broader representation of telco industry & stakeholders (incl. EU mandate, regulators, LEAs), E2E view, use cases and requirements, migration / backwards compatibility, stability.OSS: faster innovation, faster development cycles (from requirements to conformance and interop testing), design & validation of APIs, adoption outside telco industry.
Need new models of working togetherbuild on existing OSS body of work, rather than re‐designing APIscreate stable standard based on rapidly evolving implementations
Challenges & open questionsOSS coding NFV while ETSI NFV not in Stage 3 yetIPR (FRAND vs Apache 2.0 or others) to reference OpenSource API & work, exchange information, profile APIMaintenance of ETSI standards vs OpenSource 6 months release cycle
