  1. Trends in SDWAN Raghavan Kasturirangan (rkasturi@cisco.com) Principal Systems Engineer Cisco Systems

  2. Secure Cloud Scale SD-WAN

  3. Previously, Connecting Users to Data Center was the Priority Internet Applications Best Effort Users WAN Branch/Campus Data Center

  4. Today, things have changed completely Devices and Things DC/Private Cloud WAN Campus and Branch Users SaaS Mobile Users IaaS

  5. SD-WAN provides flexible connectivity and ease-of-management Campus X2-5 DC/Private Cloud Branches X100+ Intelligent connectivity becomes business critical SaaS Mobile Users X1000s IaaS • SD-WAN was About Flexible Connectivity

  6. Business Value of Cisco SD-WAN 38% Less unplanned downtime Faster to implement policy/ configuration changes Lower five-year cost of WAN operations 58% Full IDC report available on www.cisco.com/go/sdwan $14.98M increased revenue per organization 94%

  7. SD-WAN ArchitectureThe Power of Abstraction Orchestration Plane Management APIs Management Plane 3rd Party Automation Analytics 4G MPLS Orchestrator Control Plane INET Control plane Data Plane Campus Branch Cloud SOHO Data Center

  8. Cloud Ready WAN SaaS IaaS Public Cloud Data Center Cloud Applications Data Center Data Center Small Office Home Office Small Office Home Office Secure SD-WAN Fabric Secure SD-WAN Fabric Branch Campus Branch Campus Cloud On-Ramp SaaS Cloud On-Ramp IaaS

  9. Flexible ConnectivityApplication-aware Routing with any Topology Bandwidth Augmentation • Augment MPLS with Internet bandwidth Manage Manage • App Aware Routing Policy • Latency ≤ 150ms • Loss ≤ 2% • Jitter ≤ 10ms Traffic Engineering Policy Critical Application SLA Bandwidth Augmentation Internet Remote Site Remote Site Internet Path 1 A MPLS Data Center Data Center Path 2 App A B MPLS 4G LTE Path 3 SD-WAN Tunnel SD-WAN Tunnel

  10. Voice OptimizationImprove reliability with FEC and Packet Duplication • FEC guarantees voice/critical traffic across unreliable WAN links • Reduces retransmissions and improves throughput Manage • Packets sent on preferred path and a secondary path is chosen to duplicate packets • Packet duplication helps voice, video to work well over unreliable WAN links VPN1 VPN1 Forward Error Correction Packet Duplication Manage Receiver Sender Remote Site Internet Internet Data Center Parity Path 1 MPLS P2 P2 P2 P2 P2 P3 P3 P3 P3 P3 P4 P4 P4 P4 P4 P1 P1 P1 P1 P1 P1 P2 P3 P4 Data Center Remote Site Path 2 4G LTE Parity Parity Parity Path 3 P5 P5 P5 MPLS App A (VPN1) App A (VPN1)

  11. Right Security, Right Place Cisco SD-WAN Security Typical SD-WAN Solutions IPS FW SaaS SaaS IaaS IaaS Internet Internet DNS SWG • Direct Internet/Cloud Access • Exposure to attacks from Internet/cloud • Data breaches • Guest access liability • Internal Data Access • Compliance (PCI, HIPPA, GDPR) • Lateral movements CD FW SIG URL AMP Branch Data Center Threat Intelligence Secure SD-WAN Fabric Branch Data Center “No Compromise” Solution Single management console for networking and security with zero-trust fabric authentication and end-to-end segmentation that stop breach propagation. SD-WAN Fabric Challenge of Balancing Security and User Experience Adding various point-solution securities (on-premise and/or cloud) will compromise security, application experience or performance.
