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

 

One point the industry as a whole can agree on is that an agile, flexible, and intelligent network is a must-have requirement for 5G, irrespective of use case. Key to this is enabling network-wide virtualization of both the infrastructure and the essential functions that promise to accelerate the development and deployment of new applications and services. At the most recent Mobile World Congress, Netrounds, RIFT.io, Telenor, Intel, and Arctos Labs unveiled a highly relevant proof of this concept with “DevOps in Service Chains and 5G Network Slices”.

This week, the ETSI Open Source MANO (OSM) Leadership Group is pleased to announce that this proof of concept has been officially accepted as ETSI OSM PoC #1. The DevOps in Service Chains and 5G Network Slices PoC is the first of what will be many such PoCs within the OSM project. Here is a birds-eye view of the PoC courtesy of a Netrounds presentation:

ETSI NFV PoCs “help to build industry awareness and confidence in NFV as a viable technology and help to develop a diverse, open, NFV ecosystem.” In the same way, ETSI OSM PoCs build awareness and confidence in OSM as a production quality MANO solution, as well as creating momentum and collaboration amongst VNF vendors, MANO providers and integrators, and NFVI/VIM vendors. ETSI OSM PoCs also provide comprehensive feedback to the TSC and OSM community from experience with OSM in real-world use cases and multi-vendor environments.

ETSI OSM PoC #1 highlights three important advantages and capabilities made possible through cloud-enabled network virtualization, specifically:

DevOps for Telecom: By integrating the development and operations functions under one cohesive organizational structure, DevOps can compress the time required to roll out new assured applications and services, which can mean more revenue streams for operators. In other words, adopting DevOps can fully leverage the agility and flexibility benefits of network virtualization.

Simplified Service Chaining: Network virtualization, via SDN and NFV, can streamline the process for chaining various network services using a single network connection through automation and defined policies.

Network Slicing: This is the ability for operators to split a physical network into any number of virtual networks, a concept similar to server virtualization and its role in creating virtual machines. Network slicing will be a critical capability for 5G networks in order to accommodate the capacity and reliability requirements for supporting the very large number of connected devices.

The PoC integrates all three elements as part of an assured, end-to-end service fulfilment/assurance lifecycle that directly addresses the reality of complexities and frequent changes that mobile and even wireline operators must contend with today in their networks. The goal of the PoC is to demonstrate that operators can ensure that the services they are delivering meet both their contracted SLA requirements and demanding customer quality expectations. Ensuring optimal customer experience is arguably the top priority for any mobile operator, among the many challenges they face in fully rolling out 5G.

As we are kicking off the ETSI OSM PoC program, I am excited about the new opportunities that this initiative brings to tangibly demonstrate the value of OSM to advance the use cases and service deployment scenarios that are critical to operators worldwide.
