In its quest to deliver an open network functions virtualization (NFV) management and orchestration (MANO) stack for a wider implementation across different technologies, ETSI Open Source MANO (OSM) group has made some improvements in Release Two. In the second iteration, it has added new capabilities for software-defined networking (SDN) as well as a new plug-in supporting public and hybrid cloud deployments for Amazon Web Services (AWS).
Launched in October of 2016, Release ONE looked to deliver a production-quality MANO stack for NFV that was readily available to everyone and would consume published information models for all VNFs that was VIM-independent operationally significant. At the time, the group said Release ONE was engineered, tested and documented so it can be installed quickly in operator labs around the world looking to create an interoperable open source MANO environment that was fully scalable. In addition to improving interoperability with other components, it was also able to create a plug-in framework to simplify platform maintenance and an extension for providing support.
According to the group, one of the most important steps in advancing the previous version was the production readiness in 2017, which it says is a significant milestone in Release TWO. It goes on to say, “The bar the community is setting for itself before applying a ‘deployment ready’ label is high. Nonetheless, the leadership team feels comfortable in advising operators that they should now consider this release to be of sufficient functionality as a framework for PoCs and trials. Operators can also use OSM Release TWO to progress their RFx processes.”
In Release TWO, the following capabilities are now available: interoperability with other components such as virtual network functions (VNFs), virtualized infrastructure managers (VIMs) and SDN controllers, as well as an increase in the number of on-boarded VNFs.
An Amazon Web Services EC2 plug-in was created supporting public and hybrid cloud deployments.
“AWS support allows automation of NFV deployments in public clouds or in hybrid multi-site scenarios so that developers and testers of OSM and NFV orchestration will no longer need to set up a private cloud to run basic NFV use cases and tests,” said Andy Reid, vice chairman of ETSI OSM.
Improvements have also been made to make the VMware vCloud Director VIM plug-in compatible with vCloud NFV 1.5 and 2.0.
Support for ONOS as well as the previously supported ODL and Floodlight by the SDN controller can now be managed directly from the Resource Orchestrator (RO).
“The SDN assistance in Release TWO is a huge leap forward to enable full automation of key operators’ use cases with the most popular VIMs on the market,” said Francisco-Javier Ramón, chairman of ETSI OSM group.
Some of the other improvements include: packaging, distribution and installation; usability; data modeling; data plane configuration; and service assurance.
