ETSI OSM launches Release THIRTEEN with a new scalable architecture for massive closed-loop operations

Sophia Antipolis, 15 December 2022

The ETSI Open Source MANO community is proud to announce OSM Release THIRTEEN, meeting the already established cadence of two releases per year, alternating between Long Term Support (LTS) releases such as Release TWELVE (2 years’ support) and Standard releases (6 months support).

This release introduces a new scalable architecture for service assurance and closed-loop operations leveraging on cloud-native version of Apache Airflow and Prometheus. This architecture is prepared to cover the most demanding service assurance scenarios such as auto-healing and auto-scaling in large clouds and multiple edge sites. Release THIRTEEN incorporates new workflows for obtaining the state of Network Functions (NF), Network Services (NS) and VIM, and will gradually incorporate new capabilities in the next releases.

In addition, Release THIRTEEN includes significant improvements in other key areas:

  • Execution environments. Day-2 operations are a key capability in OSM, which provides added value to the mere deployment of NS and NF through the use of Execution Environments (EE), isolated environments that allow the execution of code to perform operations on the NF and NS. Release THIRTEEN provides an improved secured communication channel between helm-based EE and NF, the capability to upgrade helm-based EE and a new naming convention for Juju application in Juju-based EE.
  • Network Service (NS) deployment. OSM has proved to be successful in production environments for the deployment of NS. This release incorporates new capabilities for NS deployment such as the ability to make persistent volumes of NF permanent in the VIM, the ability to store CA certificates as part of VIM registration and updates, and the automatic WIM selection for inter-DC networks.
  • Internal LCM evolution. LCM module in OSM is responsible for managing the workflows associated with life cycle events of VNF and NS such as instantiation, termination, scaling, healing and upgrading. In this Release, we have initiated the adoption of the Saga-based pattern for workflow management in selected operations. In addition, this release incorporates the communication channel between LCM and RO via Kafka.
  • OSM installation experience. The community installer will now be able to auto-detect installations of OSM behind a web proxy and perform the appropriate configurations, easing the global installation experience. In addition, the internal process in OSM to generate the installation SW has incorporated the automatic publication of charms for charm-based installation.
  • OSM client. Finally, this release includes some improvements in the OSM client, such as a more convenient registration of Prometheus-based telemetry systems as part of VIM registration and update, the refactoring of OSM client commands, and an installation procedure for OSM client in Windows and Red Hat Linux distros in addition to Ubuntu Linux distros.
