  2. Service Lifecycle IT Policies SP Policies SP & IT Domain Tier 1 App Tier 2 App Tier 3 App Application Developer Service Request LB Inter-Connect Inter-Connect Inter-Connect Properties Properties Properties Service Mapping

  3. SDN Controller Framework Compute & Storage Controller Compute & Storage Controller Compute Domain API API Network Domain Service SPEC Policy Policy SDN Controller(s) SDN Controller(s) API API Network Specific Module Interface SPEC Network Specific Module API API Network Management System Existing APIs Network Element Control Plane Network Element Control Plane Domain A Domain B

  4. Example: Instantiate VM and connect to IP VPN SP PE VM Private Network IP VPN DC PE IPVPN VRF VM ELAN Service (ISID PBB) Application Service Request VM VM Service Mapping

  5. DC Space : SPB service instantiation Service Provider VPNs/LTE/ BNG or Internet Networks DC DC User Request (Application Definition) VPLS/IP VPN PEs Compute (VM) Management 7. ISID Service AD (SPB core) 2. Service Request Policy 4. VM Configuration Core SW B 3. Policy Verification 6. Service Instantiation ToR 5. Network Binding SDN Controller (Network Mapping & Binding) NIC NIC v-Switch v-Switch VM B New VM

  6. Use Case: VPN Configuration 7. BGP Route distribution Service Provider VPNs/LTE/ BNG or Internet Networks DC DC 1. User Request VPLS/IP VPN PEs Compute (VM) Management 6. VRF Instantiation 2. Service Request Policy Core SW 4. VM Configuration B 3. Policy Verification ToR 5. DC LAN Binding SDN Controller Network Mapping & Binding NIC NIC v-Switch v-Switch VM B New VM

  7. Limiting the Scope • Define the SDN framework (communications & schema) for • Applications & SDN controller interactions • SDN controllers to network elements and/or network management systems • Focus on simple use cases • End-to-end solution for selected use cases • Enable extensions • Allow technologies to evolve framework
