What is Cisco Viptela SD-WAN? A Beginner's Guide

SD-WAN is a virtualized network architecture that enables businesses to:

  • Use multiple connection types: Combine MPLS, broadband, LTE, and other transport technologies.
  • Improve performance: Optimize application performance by dynamically routing traffic based on policies and real-time conditions.
  • Simplify management: Centralize control through a user-friendly dashboard.
  • Reduce costs: Shift from expensive MPLS circuits to more affordable internet connections without compromising performance or security.

Key Components of Cisco Viptela SD-WAN

  1. vManage:
    • A centralized controller for configuration, monitoring, and management of the SD-WAN fabric.
    • Provides a single pane of glass for administrators to manage the entire network.
  2. vSmart Controllers:
    • Act as the brain of the network, managing control plane traffic and enforcing policies across the SD-WAN fabric.
    • Securely exchange routing and security information between devices.
  3. vBond Orchestrator:
    • Facilitates initial onboarding of SD-WAN devices.
    • Manages secure connectivity between devices and controllers.
  4. WAN Edge Devices:
    • Physical or virtual routers deployed at branch locations, data centers, and cloud environments.

Handle the forwarding of data traffic based on policies.

Key Features of Cisco Viptela SD-WAN: Simplifying Modern Networking

  1. Application-Aware Routing

    • Reduces reliance on expensive MPLS circuits, enabling hybrid WAN models with broadband and LTE.

These features make Cisco Viptela SD-WAN a modern, flexible, and secure solution for businesses transitioning to digital and cloud-first operations.

Cisco Viptela's Overlay Network Architecture

Cisco Viptela’s overlay network architecture is a software-defined, secure, and virtualized communication layer built on top of any underlying transport network (MPLS, broadband, LTE).

Key Components

  1. Overlay Tunnels: Secure IPsec tunnels connect WAN Edge devices, forming the virtual fabric.
  2. Control Plane: Managed by vSmart Controllers, which distribute routing information and enforce policies.
  3. Data Plane: Handled by WAN Edge devices, responsible for traffic forwarding.
  4. Orchestration Plane: Managed by vBond, which authenticates devices and establishes overlay tunnels.

The Role of vManage in Cisco Viptela SD-WAN

vManage is the centralized management platform in Cisco Viptela SD-WAN, serving as the control center for configuring, monitoring, and managing the entire SD-WAN fabric.

Key Responsibilities

  1. Centralized Configuration:
    • Simplifies deployment with templates for device and network configurations.
    • Enables policy definition for traffic routing, security, and QoS.
  2. Real-Time Monitoring:
    • Provides visibility into network performance, device status, and application behavior.
    • Offers analytics and insights for troubleshooting and optimization.
  3. Automation:
    • Automates onboarding of WAN Edge devices with zero-touch provisioning (ZTP).
    • Streamlines software upgrades and device management.
  4. Policy Enforcement:
    • Distributes and enforces policies across the SD-WAN fabric.
    • Controls traffic flow and ensures adherence to security and business rules.
  5. Security Management:
    • Integrates with Cisco Umbrella and other security tools for comprehensive protection.
  6. Scalability:
    • Manages thousands of devices, ensuring scalability for businesses of all sizes.

vManage is the single-pane-of-glass interface that empowers administrators to efficiently control and optimize their SD-WAN environment.
