Software-Defined WAN (SD-WAN) is an overlay architecture that overcomes the biggest drawbacks of traditional WAN. SD-WAN builds a secure, unified connectivity over any transport (MPLS, Broadband, LTE, VSAT etc.) and provides simplified operations with centralized management, policy control and application visibility across the enterprise.


Wide Area Network (WAN) connectivity models follow hybrid approach and companies may have multiple types – MPLS and Internet. Branch A has remote access over the Internet, while branch B employs private MPLS connectivity. Internet and MPLS have distinct connectivity models and different types of overlay exist for Internet and MPLS based networks. The challenge is to combine these overlays automatically and provide a transport-agnostic overlay network.

Solution – Viptela

To address these challenges, Viptela created a new overlay network-called Secure Extensible Network (SEN). For the first time, encryption is built into the solution. Security and routing are combined into one solution. Enables you to span environments, anywhere-to-anywhere in a secure deployment. Type of architecture that is not possible with today’s-traditional networking methods.

Key benefit of Viptela is any-to-any connectivity product offering. Connectivity previously found in Multiprotocol Label Switching (MPLS) networks. They purely work on the connectivity model and not security frameworks. They can however, influence-traffic path to and from security services.

  • Ubiquitous Data Plane
  • Transport Independence
  • Automatically Secure Routed Endpoints
  • Secure Network Segmentation
  • Centrally Enforce Policy
  • Advertise Layer 4 to Layer 7 Service to the Network
