SD-WAN 2.0: Building a Better SD-WAN, October 2016

  1. 1. SD-WAN 2.0: Building a Better SD-WAN SDN World Congress World Forum, The Hague, Netherlands Wednesday October 12, 2016
  2. 2. © 2016 ADVA Optical Networking. All rights reserved. 2 Q: Why Is SD-WAN Hot? A: MONEY! SD-WAN can provide enterprise VPNs at a lower cost point than today’s provider MPLS VPNs $
  3. 3. © 2016 ADVA Optical Networking. All rights reserved. 3 MPLS VPN Versus Broadband Pricing Source: “Why does MPLS cost so much more than internet connectivity?” As we saw when covering why the NEW architecture will happen MPLS is typically priced at $300 - $600 per Mbps per month for the copper connectivity typically deployed at all but the very largest enterprise locations, while the monthly price of broadband connectivity is now $1.50 - $15 per Mbps per month.

  5. 5. © 2016 ADVA Optical Networking. All rights reserved. 5 It’s Not Just Pricing! Other issues with today’s MPLS VPNs: • Slow to install and provision • Slow adds/moves/changes • Lack of application-level visibility and control
  6. 6. © 2016 ADVA Optical Networking. All rights reserved. 6 Why Not Use Broadband for VPNs? Higher loss Lower reliability Lack of security Shared, best-effort bandwidth Required management of routing for VPN
  7. 7. © 2016 ADVA Optical Networking. All rights reserved. 7 What Is Software-Defined WAN (SD-WAN)? SD-WAN is an integrated solution to enable the augmentation or replacement of MPLS VPNs with an overlay network using lower-cost broadband connections SD-WAN solutions typically provide embedded routing and firewall capabilities, policy-based flow routing and in some cases, WAN optimization SD-WAN today consists of two parts: • A central controller, often hosted in cloud • Access nodes deployed at access sites
  8. 8. © 2016 ADVA Optical Networking. All rights reserved. 8 SD-WAN Controller The central controller: • Provides the command and control aspects of SD-WAN • Can run on the user’s site or hosted in the cloud The controller normally includes these capabilities: • Acting as a repository for configuration of the access nodes • Administering the network topology • Setting and distributing policies for QoS and access • Reporting usage and performance
  9. 9. © 2016 ADVA Optical Networking. All rights reserved. 9 SD-WAN Per-Site Access Nodes May be implemented as an appliance or a VNF on a server and include many or most of the following functions: • Zero-touch commissioning • Routing and tunneling engine • Hybrid WAN • Firewall and security • QoS and access policy • WAN optimization • Network loss and latency measurements
  10. 10. © 2016 ADVA Optical Networking. All rights reserved. 10 SD-WAN Benefits • Lower cost for VPNs • Access flexibility and redundancy • All-in-one solution • Policy-based control • Works over a variety of media
  11. 11. © 2016 ADVA Optical Networking. All rights reserved. 11 Current SD-WAN Limitations • SD-WAN is standalone • SD-WAN is monolithic • SD-WAN couples service and technology • SD-WAN implementations are large • SD-WAN is a pure overlay technology • SD-WAN is user-managed
  12. 12. © 2016 ADVA Optical Networking. All rights reserved. 12 SD-WAN 2.0: The Next Step Evolve SD-WAN by leveraging foundation of virtualization, NFV and SDN. Improvements over SD-WAN: • Scalable: Implemented as components using VNFs or containers • Network-focused: Supports underlay and overlay models • Flexible: QoS measurements decoupled from policy • Modular: Enables service providers to continue to select best-of- breed components for routing, firewall, DPI, etc. • Extensible: Platform available for innovative services • Managed: Designed to enable operators to offer as a part of managed services
