ETSI Open Source MANO (OSM) Activity Report 2019

Chair: Francisco-Javier Ramón Salguero, Telefónica S.A.

Established as a community driven initiative – hosted by ETSI – to develop a production-quality NFV Management and Orchestration (MANO) software stack aligned the requirements of commercial NFV networks.

ETSI continues to actively explore synergies between the worlds of Open Source and standardization in its work on NFV. Two key components of ETSI’s NFV architectural framework are the NFV orchestrator and the virtualized network function manager – known collectively as the NFV Management and Orchestration, or MANO.

To enable accelerated standardization with a fast feedback loop to our NFV Industry Specification Group, our Open Source MANO group (ETSI OSG OSM) is developing a software reference implementation example for the ETSI NFV MANO along with Slice Manager functionality, according to accepted Open Source working procedures and using a software development platform hosted and managed by ETSI.

OSM is a community driven effort that aims to offer a production-quality Open Source MANO stack that meets the requirements of commercial NFV networks.

It was confirmed during 2019 that earlier OSM Releases (ONE to SIX) have been downloaded more than 15,000 times from 85+ countries.

Delivered in June, OSM Release SIX brought many new capabilities to provide end-to-end orchestration across heterogeneous networks and cloud technologies. Among a large number of enhancements, Release SIX makes the management of complex services easier thanks to the extended capabilities to create Network Service primitives and the extension of its Service Assurance (SA) framework, which now can control, store and react to a much wider set of events and conditions in the context of running Network Services and Slices.

In addition, Release SIX further widens the range of underlying technologies that are supported by OSM. New connectors have been developed for FOG05 Edge clouds, TAPI-based transport networks, VMware’s vCloud Director 9.5, and public clouds. Similarly, various improvements have been added to the already large set of connectors available from previous releases to support additional EPA attributes and ameliorate the support of underlays with the addition of multi-segment networks.

Delivered in December 2019, OSM Release SEVEN has brought cloud-native applications to NFV deployments, enabling OSM to on-board over 20,000 pre-existing production-ready Kubernetes applications, with no need of any translation or repackaging. Release SEVEN allows combination within the same Network Service the flexibility of cloud-native applications with the predictability of traditional virtual and physical network functions (VNFs and PNFs) and all the required advanced networking required to build complex end to end telecom services.

Release SEVEN extends OSM's SDN framework to support the next generation of SDN solutions providing higher level primitives, increasing the number of available options for supporting I/O-intensive applications. Furthermore, plugin models for intra and inter-datacenter SDN have been consolidated and the management, addition and maintenance of SDN plugins significantly simplified.

The power of OSM to help orchestrate 5G networks was illustrated in March 2019, when the University of Bristol’s Smart Internet Lab conducted a unique multi-site live music concert. Performers in Bristol and London were linked in real time via low latency, high capacity 5G connections orchestrated by ETSI OSM.

Open Source collaboration is a hallmark of our popular Hackathons and Hackfest events that provide a platform for the IT development community to validate ETSI specifications through live demonstrations and practical challenges. These plenaries, mid-release meetings and accompanying Hackfest events were held during the year:

  • OSM Mid-Release SIX meeting and Hackfest, Barcelona (February)
  • OSM Release SEVEN Plenary meeting and Hackfest, Santa Clara (May)
  • OSM Mid-Release SEVEN meeting and Hackfest, Patras (September)
  • OSM Release EIGHT Plenary meeting and Hackfest, Lucca (November)

Collaboration with other projects and bodies has remained a key aspect of our work. During the year OSM maintained close links with our ETSI NFV, Multi-Access Edge Computing (MEC) and Zero Touch Network and Service Management (ZSM) ISGs and other bodies dealing with 5G technologies.

There are currently 22 EU Projects working on 5G research that are using and contributing code and feedback to OSM.
