OPEN-O Mission & Scope • Enabling end-to-end service agility across SDN, NFV, and legacy networks via a unified orchestration platform supporting NFV orchestration (NFVO and VNFM) and SDN orchestration. • This platform will be implemented and periodically released as open source software. Its modular nature will support common and vendor-specific data models and interoperability across multiple controllers, VNFs, VIMs and VNFMs. • Open-O will allow service providers to maximize the use of available network capacity, reduce customization, and accelerate innovation in a multivendor ecosystem OPEN-O SW Architecture • End-to-End SDN/NFV Orchestration • ETSI NFV MANO compliant • Modular and multiplatform • Service and Resource Orchestration • YANG and TOSCA support Use Case Example: eHealth application of SDN + NFV User Story: 1. A doctor sends a patient to the hospital for X-rays 2. The doctor needs to set up a VPN connection between his office and the hospital (L2/L3 vpn) to download the X-Rays 3. Both the doctor and the hospital need to turn on L2 + L3 firewall VNFs VPN 4. They also need to turn on encryption 5. The VPN should adjust the amount of bandwidth it delivers – for example, a lot of bandwidth for the X- rays, but only a little for billing records Sequence Diagram for eHealth Use Case Common Cross SDN Ctrl.
