WHAT IS OSM?

OSM is developing an open source Management and Orchestration (MANO) stack aligned with ETSI NFV Information Models. As a community-led project, OSM delivers a production-quality MANO stack that meets operators' requirements for commercial NFV deployments.

ETSI NFV Alignment

OSM is closely aligned with the evolution of ETSI NFV and provides a regularly updated reference implementation of NFV MANO.

Open Source

ETSI OSM uses well-established tools and methods to develop code under the Apache Public License 2.0.

Open Community

Participation to OSM is open to members and non-members of ETSI, as well as individual developers and end users from all across the globe. Check how to join or learn more about OSM.

WHAT PEOPLE ARE SAYING

“Operational effectiveness at the edge is critical to a successful 5G strategy and emerging business models for edge-based compute. OSM Release SIX connects edge and core to provide repeatable and reusable services that span the full telco topology and enable both 5G infrastructure and third-party app ecosystems for the edge in VMs and containers.”

Mark Shuttleworth

CEO of Canonical and founder of Ubuntu

“Management and Orchestration (MANO) is, at the same time, one of the key components and most controversial concepts in network virtualization architecture. Telefónica has long been working from the point of view of innovation in its development. A first result and seed of OSM is OpenMANO, a highly functional framework pioneering the first open source NFV Orchestration and Management stack and, currently, a key component of Telefónica’s NFV Reference Lab. By joining this community, we aim to accelerate the development of MANO while recognizing the value of open-source implementations of NFV and a need to harmonize efforts there.”

Antonio Elizondo

Head of Network Virtualisation Strategy and Technology, Global CTO Unit, Telefónica

“OSM has evolved from an interesting PoC into the most promising architecture for orchestrating VNFs, under the multi-vendor, standardized approach that our Telco customers have been looking for. Increased robustness, as well as exciting features that pave the path towards 5G and the Edge, let us build with confidence the second release of our distribution, WhiteNFV Barcelona, in order to cover the increased demand for operator-led, automated NFV deployments.”

Joris Vleminckx

COO Whitestack

“The ETSI OSG Open Source MANO (OSM) initiative will facilitate the development of open source software for management and orchestration of future networks. Knowledge, capabilities and solutions within this area will be of critical importance to Telenor when virtualizing the network for increased flexibility, faster service delivery, rapid innovation and operational efficiency.”

Patrick Waldemar

Vice President, Telenor Research

“Proprietary management and automation approaches have impeded NFV deployments. Service providers recognize the need for a standardized MANO information model delivered in conjunction with an open source MANO platform to cultivate a robust commercial NFV supplier ecosystem. I’m thrilled with the progress OSM has made to meet these needs and its growing industry acceptance.”

Matt Harper

OSM Founding Member, CTO, RIFT.io

RADCOM premiered their MaveriQ solution running on OSM to show that the tight integration of the service assurance stack with OSM can enable on-demand virtual probing that will be automatically deployed and configured when new services are launched or service changes are made. The power play here is thorough monitoring of customer experience and service performance using real-time packet capture so that horizontal and vertical scaling can occur without human intervention to accommodate fluctuating network traffic and resource needs. 

In the RIFT.io booth, Telenor, Intel, Netrounds, Arctos Labs and RIFT.io debuted their DevOps in Service Chains and 5G Network Slices PoC. What are the key takeaways here? Active testing is key for implementing DevOps agility into virtual and 5G networks, and automated test and monitoring will be critical for operators to deliver assured services in these increasingly complex and dynamic environments. The PoC goes deeper technically to illustrate that active test agents should be included in network service design stages so that service models describe which KPIs to actively measure and assure throughout the service lifecycle.Are you sensing a common theme? Testing, monitoring, automation. Testing, monitoring, automation. 

Finally, proceeding to the Canonical stand, we saw Ixia, DataArt Solutions and Sonus teaming up with Canonical to demonstrate the integration of automated VNF verification for network services using OSM. The main takeaway from this PoC is that the automated deployment and execution of carrier-grade network testing and service monitoring will be critical for the assurance of service quality in diverse, virtual network environments. So once again, the themes of testing, monitoring and automation makes their way to the forefront.

When the Open Source MANO team put out a call to action for OSM participating organizations showing demonstrations of OSM at MWC, we did not expect to receive word of demonstrations that all relate to testing and monitoring virtualized network services. Although the companies participating in the PoCs do more than NFV T&M, it is apparent that the role of active testing is only making its silver screen debut in what will be a very long career. Pairing our T&M leading lady with advanced service and resource orchestrator players on the virtual scene will enable end-to-end service assurance in a completely automated fashion – even when the whims of the capricious director call for small cast alterations here, a scene reassessment there, or a full-on location change. Service assurance may be trending and in the spotlight today, but with the desire for added dynamism and dynamite service quality for increasingly demanding patrons, it is no surprise that vendors in our space are rushing to remedy any foreseeable problems so that service providers will receive all five stars from their harshest critics (the subscribers). 

If you missed OSM at Mobile World Congress, we will be present at several industry events coming soon. Catch us at the MPLS + NFV + SDN World Congress coming up in Paris from March 21st to 24th. There will be an OSM Session on Tuesday the 21st starting at 14:00 that will include an OSM overview and two live demos.
