• OPNFV creates a platform for NFV

• OPNVF collaborates with existing upstream projects and initiatives• Open source projects and standards

organizations/industry fora• Forking is strongly discouraged

• Focus is on integration, closing of gaps, testing• Code development would typically happen in

upstream projects• If code development within OPNFV is required,

it’ll use Apache license version 2.0

Theme: “Run my VNF for real” Assemble a minimal set of base infrastructure to enable real-world VNF deployments

• Predictable performance – Deploy to bare metal

• Validated – Functional testing, multiple test environments

• Repeatable – Automatic deployment

• Carrier-class – High availability

• Servers• >= 3 Control nodes• >= 2 Compute nodes• 1 Provisioning node (“jumphost”)

(Centos 7, runs test infra and installer VM)

• Services• No additional services (e.g. DHCP)

available on subnets. Installers runservices that are required themselves

• Remote access for community members• Lights-out-management (IPMI, PXE boot)

Summary & Closing Thoughts

© 2015 Cisco and/or its affiliates. All rights reserved. Cisco PublicDEVNET-1162

Summary• OPNFV – Systems-integration as an

open, meritocratic, community effort

• Starting point (“Arno” release): • “dotadiw” approach to get started• Lab/developer focused first release• “Run my VNF for real” mind set:

Deploy to bare metal with HA• Instantiate cross-project CI/CD tool chain• Distributed lab infrastructure

• Multiple ways to leverage and participate in OPNFV: Run your VNF, get your use-cases/test-cases implemented, articulate your requirements• User uptake to determine OPNFV’s success:

Can common merit be achieved quickly enough to achieve industry acceptance?

© 2015 Cisco and/or its affiliates. All rights reserved. Cisco PublicDEVNET-1162

Closing thoughts• NFV base infrastructure is a natural candidate for

open-source and community driven development• “Hard work” – “Low on IP”, … but integration is still an art

• NFV base infrastructure has a strong systems-integration aspect:Choose vs. Choice• Systems-integration is about picking, choosing and Trust• Open-Source is about creating choice and recognizing merit created• … Could a meritocratic approach provide for a solution?

• Create and Maintain one Open Platform for NFV – adhere to “dotiadiw” • Verification (test driven) definition of OPNFV target system state moving forward?
