  3. Router Offload

  4. L3 Router OffloadService Orchestration Use Case • Internet edge Offload • Extending the life of edge interfaces by keeping intra-metro traffic in the metro • Data Centre Gateway optimization • Selective routing of inter-DC traffic before traffic hits the DC gateway. • Provide fine-grained control of traffic flows to support low latency/cost DC interconnect CYAN CONFIDENTIAL

  5. Layer 3 Offload Use-Case Route Reflector IBGP L2 Aggregation L2 Aggregation L3 Offload #1 PE #1 j j CPE #1 CPE #4 CPE #2 CPE #3 IP/MPLS Core IBGP PE #2 L3 Offload #2 Static routing/eBGP CYAN CONFIDENTIAL

  6. L3 Router OffloadOrchestration Requirements • OpenFlow used for south-bound control to keep the solution open & flexible. • Dynamic OpenFlow methodology used to discover offload physical topology. • SDN controller talks BGP to learn logical topology. • Mapping between existing and new offload topology configured via API. • Policy-Based Offload: • Traffic analysis determines candidate routes for offload • L3 switch FIB limiting factor in solution scalability CYAN CONFIDENTIAL

  9. SDN Use Case WAN + CloudService Orchestration

  10. Data Center Interconnect (DCI) Scenario • Virtualization has made compute all singing and dancing • Network aren’t currently as agile • Lack of orchestration mandates too much or not enough… Demand-based migration of VMs, compute tasks, and content Insufficient resources or overprovisioned bandwidth Data Center Data Center Ethernet & Optical Carrier Network CYAN CONFIDENTIAL

  11. Enterprise toCloud Connectivity Business Apps OSS Customer Front-End SDN Orchestration & Back-End Network Virtualization Self-Provisioning SLA Monitoring Performance Management Usage Billing APIs Automatic allocation of data center resources including VMs 3 Multi-Vendor Element Adapters Customer Portal PCE and A-to-Z Provisioning OpenFlow OpenStack & Quantum Customer orders cloud service (e.g. IaaS) Data center connectivity automatically provisioned 1 2 Data Center Data Center Enterprise Ethernet & Optical Carrier Network CYAN CONFIDENTIAL
