ABSTRACT:
A node size estimation tool for calculating a node size for interactive video, voice or data services placed on a system is provided. The estimation tool includes a computer processor, a data storage device, and the data entry device. Inputs are provided for receiving data on bandwidths for downstream and upstream passbands and for receiving data on node splitting information. Inputs are provided for receiving data on any limitations on the upstream and downstream passbands that are unavailable for use by the system. Inputs are provided for receiving data on requirement information for various services, and for receiving data on estimated service penetration rates, estimated simultaneous use rates, and a desired downstream data rate. Also, inputs are provided for processing data received to calculate the node size. A method of calculating node size utilizing the tool is also provided.
