\nObjectives:<\/span><\/strong><\/h4>\n

Softwarization and virtualization are recent network technologies expected to be more and more adopted in next-generation networks and already intensively used in current terrestrial infrastructures, from cloud environments to mobile networks. They operate in synergy by decoupling network functionalities from the underlying hardware.
\nWhen used together, they allow the creation of software instances of network functions and digitalized services that were traditionally hard-coded into network equipment and most often tied to a specific manufacturer or model.<\/p>\n

The main objective of the project is to design, develop, and test fully virtualized ground software components that can be deployed, configured and scaled dynamically over shared infrastructures exploiting edge or cloud resources. Orchestration and network automation mechanisms can combine, manage and control such components, exploiting their open programmability, to build and deliver end-to-end services supported by both flexible high throughput satellites and terrestrial networks among multiple end-users and service providers.<\/p>\n

The resulting virtualized platform is deemed fundamental to ease the creation procedure and management of Satellite Virtual Network Operators (SVNOs), through simplified north bound interfaces to allow a complete while simple management of the terrestrial and satellite physical resources available.<\/p>\n

 <\/p>\n

Challenges<\/strong><\/span><\/h4>\n

The application of the network virtualization and automation paradigms to the satellite is not straightforward, because resource \u201cslicing\u201d is more than a simple network partition. It needs an increased flexibility in the network management, for the satellite network operator, and an overall abstraction and virtualization of the complex physical infrastructure underneath, specifically extended to the satellite ground segment. The landscape is further complicated by considering that the satellite standpoint is often based on legacy or proprietary technologies, software and hardware, quite far from terrestrial networks with additional challenges related to virtualization techniques, deployment constraints and programmability.<\/p>\n

 <\/p>\n

Benefits<\/strong><\/span><\/h4>\n

The virtualization and the centralized orchestration of satellite resources within end-to-end multi-domain network infrastructures open to the definition of new added-value services extended towards a larger group of end-user devices and applications. Fully digitalized and orchestrated satellite resources, considering flexible HTS SatCom payloads and integration with software based terrestrial networks, bring several advantages and allow a much more effective and efficient SatCom utilization.<\/p>\n

System architecture<\/strong><\/span><\/h4>\n

The possibilities enabled by accessing fully digitalized and orchestrated satellite and terrestrial resources are manifold:<\/p>\n

    \n

      \n
    1. Leveraging the key characteristics of satellite communication (SatCom) technologies, such as broadcast and coverage, in an efficient and smart way following a top-down and multitenancy configuration approach.<\/li>\n
    2. Offering smooth integration with virtualized terrestrial infrastructures, introducing innovative multi-domain orchestration concepts.<\/li>\n
    3. Reducing service costs and improving operational aspects (i.e., time to setup a service, or reconfigure it in case of need or failure) by enabling network resources, either satellite or terrestrial or both, on demand, in fully automated way.<\/li>\n
    4. Fostering in-network functions and network digitalization\/virtualization functions directly onboard of future satellite payloads.<\/li>\n
    5. Ensuring market compatibility thanks to the possibility of exploiting working principles of already consolidated network architectures, such as the one foreseen by 3GPP specifications and ETSI-MANO initiatives, as well as well-established virtualization infrastructures (VIM, orchestration) and technologies (i.e., SDN, SDR), network monitoring and automation, etc.<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n
