DHCP Lease Forecasting Windows

Forecasting in DDI Central for DHCP leases allows network admins to forecast their organization network's DHCP services performance by analyzing the historical data.

These dashboards provide visual summarization over the network trends, volumes, intensity and more.

Note: DHCP lease forecasting is available for both DHCPv4 and v6 addresses in the network.

Note: For minimum level of forecasting, historical data need to be under the following criteria

  • 24 hours data forecast requires at least minimum two days historical data.
  • 7 and 30 days data forecast requires at least minimum 14 days historical data.
  • 3, and 6, and 12 month data forecast requires at least minimum of 4 months historical data.

For accurate forecasting, historical data needs to be double the forecasting time period:

  • 7 day forecast requires 14 days of historical data.
  • 30 days forecast requires 60 days of historical data
  • 3 month forecast requires 6 months of historical data
  • 6 month forecast requires 12 months of historical data
  • 12 month forecast requires 24 months of historical data

For more accurate forecasting, DDI application in the network is expected to have consistent historical data for the projected time period of forecasting.

Ex: In order to forecast DHCP leases for the next 30 days, the application need to have consistent data for the last 30 days for accurate forecasting.

If theres a significant drop in the data input, the prediction may not be valid.

DHCP lease forecasting can be view by going through IPAM>Lease, and selecting a specific subnet and clicking on Forecast option.

In DHCP lease forecasting, the dashboard shows the following data:

  • Predicted Trend: Percentage value of predicted spike or downgrade in DHCP lease count compared to the historical data.
  • Total Forecast: The total increase or decrease in the lease count that is predicted based on the historical data.
  • Intensity: The increase or decrease in the lease count on business hours (9-6) and non-business hours in hourly basis, and for daily basis, it is based on business days and non-business days.
  • Average Volume: Average increase or decrease in lease volume per time metrics configured, that is predicted based on the historical data.
  • Average Unique Clients: Average increase or decrease in DHCP requests sent by clients that is predicted based on the historical data.
  • strong>Average Leases per Client: Average increase or decrease in DHCP leases leased per every client that is predicted based on the historical data.
  • Utilization Trend: The time period that could be taken to reach the 90% lease utilization capacity.
  • Average Lease Duration: Average lease duration period that is predicted based on the historical data.
  • Note: DHCP host reservation data and static lease data wont be used for DHCP lease forecasting.
