VNI (Visual Networking Index): Understanding Global IP Traffic Growth

VNI, or Cisco Visual Networking Index, isn't directly related to Network Functions Virtualization (NFV) concepts like VNFD or VNFM. However, it's a valuable resource for understanding global internet traffic trends, which are crucial factors considered in NFV deployments. Here's a breakdown of VNI:

What is VNI?

VNI is a global forecast published by Cisco that analyzes and predicts future trends in internet protocol (IP) traffic. It provides insights into:

  • Traffic Growth: The projected annual growth rate of global IP traffic.
  • Traffic Volume: The estimated volume of IP traffic generated per year, typically measured in Exabytes (EB) or Zettabytes (ZB).
  • Traffic Sources: The breakdown of traffic by application, device type, and user activity (e.g., video streaming, social networking).
  • Regional Trends: Forecasts for IP traffic growth in different geographic regions.

Importance of VNI for NFV:

While not directly related to NFV technologies, VNI data is crucial for network operators and service providers deploying NFV solutions. Here's why:

  • Capacity Planning: VNI forecasts help network operators anticipate future traffic demands. This information is essential for planning infrastructure capacity and scaling NFV deployments to handle the expected traffic growth.
  • Service Design: Understanding traffic patterns and user trends can inform the design and deployment of new virtual network services. VNI data can help identify areas of high demand and opportunities for innovative services.
  • Resource Allocation: VNI forecasts can be used to optimize resource allocation within NFV environments. Knowing the expected traffic volume helps determine the required compute, storage, and network resources for VNFs.

Accessing VNI Data:

Cisco publishes VNI reports and white papers periodically. These resources provide detailed information on global IP traffic trends and forecasts. You can find VNI reports on theCisco website.

Conclusion:

The VNI from Cisco is a valuable tool for understanding global internet traffic patterns. While not directly an NFV technology, VNI data plays a crucial role in informing NFV deployments by helping network operators plan for future traffic demands and optimize resource allocation for their virtualized network services.
