Abstract:
A method of determining the throughput capacity of an access node adapted to service a plurality of terminals in a communications network, said access node being coupleable to an Internet Protocol (IP) network, said method comprising:inputting network parameters, said network parameters including a number of subscribers using said terminals, an average number of data transfer requests per subscriber in a peak time period, access line speed of said terminals, average file size of said data transfer requests, average packet size of said data transfer requests, and a desired grade of service (GoS); and determining the required throughput capacity of said access node based on the number of terminal data transfer requests, wherein said determining step comprises: calculating the mean incoming rate of data transfer requests; calculating the mean duration for data transfer; determining the upper bound of the number of simultaneous data transfer requests meeting said desired GoS; calculating the average packet transfer rate per data transfer; and calculating the edge router throughput capacity.
