ETSI Open Source MANO LAUNCHES RELEASE TWELVE with enhanced network function resiliency and runtime operations


Sophia Antipolis, 30 June 2021:: ETSI OSM is pleased to announce OSM Release TWELVE, the second Long Term Support release of ETSI Open Source MANO and one of its most prolific releases. One of the main new features of Release TWELVE is the ability to heal network functions that may be affected by any kind of infrastructure failure. This healing process, which may be triggered either manually or automatically depending on operator preference, can be applied in all the clouds supported by OSM, in line with OSM’s multi-cloud approach.

In addition to significant improvements in day-2 operation of a network service, this release makes it possible to upgrade a running network function instance with a new package version, all with minimal downtime. Moreover, the composition of network services can also be modified in runtime.

To further increase interoperability with 3rd party solutions, ETSI OSM Release TWELVE supports additional ETSI NFV Specifications, such as ETSI GS NFV-SOL003 for VNF Lifecycle Management. With the support of the VNF Lifecycle Management APIs, Release TWELVE offers both the API of an NFV Orchestrator and the API of a Generic VNF Manager, providing operators with additional options for the integration of OSM in their Telco Cloud Architecture. This support of additional ETSI NFV specs continues the journey initiated since OSM creation, where ETSI GS NFV-SOL005 was already the foundation of OSM’s northbound interface, OSM data model and descriptors were derived from ETSI GS-NFV SOL 006, and its NF and NS package formats were also based on ETSI GS-NFV SOL 004 and ETSI GS-NFV SOL 007.

Finally, this new Release includes several interesting features for production deployment, such as the support of anti-affinity groups per VNF, the addition of password expiry policies, new options for Kubernetes cluster registration, and the experimental migration of Openstack-based network function instances.

OSM Release TWELVE is the second Long Term Support release (see OSM Release TEN declared LTS), and will provide two years of continuous support with bug fixes and security patches.

And the winner is…

This month was also the date of the remote OSM13 Hackfest featuring a Team Challenge aiming to on-board Magma 5G Core. The event was run as a team challenge with 6 teams collaborating through the week on the onboarding tasks and demonstrations. The best demo was awarded, briefings and videos are available here.

During the same week, the OSM#13 Ecosystem Day allowed organizations in the OSM Ecosystem to share their experience and how OSM is helping them to achieve their goals. Presentations and demos covered a wide range of aspects from research activities to production deployments, focusing on cutting-edge Telco use cases, such as Edge/MEC, 5G deployments and Wide Area Networks (WAN).
