ETSI has announced the availability of Release Four of its Open Source MANO (OSM) spec for NFV, which it says constitutes a huge leap forward in terms of functionality, user experience and maturity.
The new release brings a number of architectural improvements that result in a more efficient behavior and much leaner footprint – up to 75% less RAM consumption. Additionally, its new northbound interface, aligned with ETSI NFV work, and the brand-new cloud-native setup, facilitate OSM’s installation and operation, while making OSM more open and simpler to integrate with pluggable modules and external systems, such as the existing OSS.
New functionalities of OSM Release Four are particularly relevant from a usability and interoperability perspective:
- New northbound interface, aligned with ETSI NFV specification SOL005 [PDF], providing a single pane of glass to control the OSM system. To facilitate the interoperability with existing and new client applications, the details of the interface are entirely available in OpenAPI format.
- Monitoring and closed-loop capabilities have also been extended. On-demand and descriptor-driven setting of alarms and metrics are now much simpler and convenient to configure and consume. Likewise, the support of push notifications and configuration of reactive policies, via the new Policy Manager, opens the door to closed-loop operations.
- Modeling and networking logic have also been enhanced. The full support of IP profiles, the consistency checking of addressing, the ability to configure specific MAC addresses for non-cloud-native VNFs, the support of service function chaining assisted by the VIM, or the possibility of using alternative images for public clouds, are only some examples. It also sets a solid path for the support of native charms – so that conventional Juju applications can run natively in OSM – and for the seamless management of Physical Network Functions (PNFs) or hybrid components (physical and virtual), enabling a true end to end service orchestration across virtual and physical network domains.
ESTI says that since Release Three, 17 new members have joined the OSM group: Amazon Web Services, Comptel, Datatronics, FBK, Infoblox, Instituto de Telecomunicações, King’s College, Keysight Technologies, Korea Telecom, Mujico, Mycom OSI, Pensa, Mantica Solutions, Tata Elxsi, University of Bristol, University of Lancaster, University of Surrey and Virtuosys.
