“OpenStack has been a key enabler for radical transformation in the telecom industry, but there is still important work to be done in bridging the OSM and OpenStack communities and projects. Mirantis pioneered a popular NFV orchestration project in OpenStack (Murano), which today is used and co-engineered by carriers and telecom vendors such as AT&T, Saudi Telecom, Comcast, Telefonica, Fujitsu, Cisco, Huawei, and countless others. The formation of OSM will unite us in driving projects like Murano forward.”

Boris Renski

CMO, Mirantis

“Management and Orchestration (MANO) is, at the same time, one of the key components and most controversial concepts in network virtualization architecture. Telefónica has long been working from the point of view of innovation in its development. A first result and seed of OSM is OpenMANO, a highly functional framework pioneering the first open source NFV Orchestration and Management stack and, currently, a key component of Telefónica’s NFV Reference Lab. By joining this community, we aim to accelerate the development of MANO while recognizing the value of open-source implementations of NFV and a need to harmonize efforts there.”

Antonio Elizondo

Head of Network Virtualisation Strategy and Technology, Global CTO Unit, Telefónica

“ETSI OSM complements the work of the ETSI NFV ISG and vice versa. It will provide an opportunity to capitalize on the synergy between standardization and open source approaches by accessing a greater and more diverse set of contributors and developers than would normally be possible. This maximizes innovation, efficiency and time to market and ensures a continuing series of conformant reference implementations.”

Luis Jorge Romero

Director General, ETSI

“The ETSI OSG Open Source MANO (OSM) initiative will facilitate the development of open source software for management and orchestration of future networks. Knowledge, capabilities and solutions within this area will be of critical importance to Telenor when virtualizing the network for increased flexibility, faster service delivery, rapid innovation and operational efficiency.”

Patrick Waldemar

Vice President, Telenor Research

“Proprietary management and automation approaches have impeded NFV deployments. Service providers recognize the need for a standardized MANO information model delivered in conjunction with an open source MANO platform to cultivate a robust commercial NFV supplier ecosystem. I’m thrilled with the progress OSM has made to meet these needs and its growing industry acceptance.”
