ETSI Open Source MANO (OSM) Activity Report 2020

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.

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. ETSI OSM is an operator-led ETSI community, delivering a production-quality open source MANO stack aligned with ETSI NFV Information Models and meeting the requirements of production NFV networks.

Unveiled in July 2020, OSM Release EIGHT added ultra-scalable service assurance capabilities and support for new resilience schemes. It also facilitated visual operation for large-scale network deployments from Cloud to Edge. For this Release, OSM’s VNF Configuration and Abstraction layer (VCA) introduced a new scheme for high-availability setups that greatly improves its resiliency to potential outage events. It also extended the support and flexibility of configuration tasks for the various components within a Network Service or a Network Slice.

Launched in December, OSM Release NINE completes the alignment process with ETSI NFV specifications, culminating in native adoption of ETSI’s previously-published Group Specification [GS NFV-SOL 006] for network functions and service modelling. Standardizing the onboarding process for VNFs into OSM fosters interoperability and boosts the growth of OSM’s VNF ecosystem. As a result of this journey, OSM has acquired quite significant experience on the practical implementation of this spec, capturing a number of suggestions for its refinement which were shared with ETSI NFV, as part of OSM’s commitment to help to extend and refine relevant ETSI specifications.

Highlights of Release NINE include:

  • Next Generation of Resource Orchestration: enables OSM to manage differential scenarios and be ready for smooth support of the rollback and resumption of new deployments over different infrastructures.
  • Extended VNF and CNF lifecycle management: the VNF configuration engine has been extended to support Helm 3, the new version of the package format for Kubernetes applications, and to allow the centralized operation of distributed CNFs. Among other benefits, this improves the resiliency of highly distributed edge deployments.
  • Smooth integration with external systems: production deployments require the integration of OSM with external systems, which has been significantly simplified in this release after the first production deployments of OSM, with enhancements in role-based access control (RBAC) and support for standardized subscription and notification APIs for OSS/BSS.
  • User Interface improvements: multi-tenancy has been added to OSM’s Grafana dashboard along with numerous improvements in the Graphical User Interface (GUI).

The launch of Release NINE coincided with the announcement of a new production deployment, confirming OSM as the most comprehensive open-source NFV orchestrator and a key enabler for zero-touch end-to-end network and service automation.

Originally scheduled as physical events, four OSM Hackfests were run virtually during the year, while still allowing participants to complete hands-on sessions remotely in a shared lab environment provided by ETSI through its Hub for Interoperability and Validation (HIVE).
