Self-Service Orchestration Alliance (showcase)MEF 3.0 – Service Fulfillment and Activation across multi-operator networks
• Create a L3VPN service spanning at least 3 Operators, terminating on a VM in a cloud service and integrate SD-WAN
• Use the L3VPN service for cloud services (e.g. stream video to a user device)
• Use LSO Innovation Platform to develop SOF functionalities and applications
• The setup is being turned into permanent MEF sandbox project, open to all MEF members.
