System, method and computer-readable storage medium for calculating addressing and bandwidth requirements of a network

Abstract

Apparatuses, methods and computer-readable storage mediums are provided for calculating estimated addressing and bandwidth requirements of a customer domain, such as to facilitate designing the respective domain. A method includes selecting customer premises equipment (CPE) of a domain including a plurality of CPEs, where each CPE includes one or more devices, and one of the one or more devices include an interface with which the domain communicates with the respective CPE. The method also includes determining if the interface of the selected CPE comprises a router, and calculating an addressing requirement of the selected CPE, where the addressing requirement includes a number of device addresses for the selected CPE. The method may additionally or alternatively include analyzing traffic patterns of the selected CPE with respect to one or more other CPEs, and based on the analysis, calculating a bandwidth requirement of the selected CPE.
