A rapid tool to dimension broadband nodes in the access

All the existing and planned broadband access delivery systems have at least one point where some concentration takes place. This broadband node concentrates a large number of services with different behaviour such as take rates, usages and bandwidths. Then, there is a need for a dimensioning tool to size these nodes where concentration takes place. A blocking model is presented along with a relevant service set definition. This work is then used to develop a dimensioning tool for broadband nodes in the access system. The tool can be used to determine the bandwidth needed to serve a given population or, with a given bandwidth, to evaluate the population served
