Abstract
A packet-based communications network is dimensioned based on a maximum number of users able to receive a predetermined target throughput of data over a predetermined number of channels. For each of an incremental number of users, at least one blocking probability is calculated, based on a traffic distribution model, and a service delay is calculated, based on the blocking probability. An iterative throughput, corresponding to each of the incremental number of users, is determined based on the corresponding blocking probability and service delay. Each iterative throughput is compared to the target throughput. The maximum number of users is identified as the number of users having a corresponding iterative throughput that is closest to and less than target throughput.
Claims14
A method for dimensioning a communications network, comprising:
- receiving a predetermined target throughput, a predetermined number of terminals, and an average user load;
- calculating a throughput value based upon the predetermined number of terminals and the average user load;
- and
- determining, with a processor, the minimum number of channels needed to support the predetermined number of terminals at the predetermined target throughput, based upon the calculated throughput value, wherein the calculated throughput value is based upon a service delay and wherein the service delay is calculated based upon a blocking probability.
A computer system for dimensioning a communications network, the computer system comprising:
- a memory that stores executable instructions;
- and
- a processor, that executes the executable instructions, to:
- receive a predetermined target throughput, a predetermined number of terminals, and an average user load;
- calculate a throughput value based upon the predetermined number of terminals and the average user load;
- and
- determine the minimum number of channels needed to support the predetermined number of terminals at the predetermined target throughput, based upon the calculated throughput value, wherein the calculated throughput value is based upon a service delay and wherein the service delay is calculated based upon a blocking probability.
A non-transitory computer-readable storage medium encoded with an executable computer program for dimensioning a communications network and that, when executed by a processor, causes the processor to perform operations comprising:
- receiving a predetermined target throughput, a predetermined number of terminals, and an average user load;
- calculating a throughput value based upon the predetermined number of terminals and the average user load;
- and
- determining, with a processor, the minimum number of channels needed to support the predetermined number of terminals at the predetermined target throughput, based upon the calculated throughput value, wherein the calculated throughput value is based upon a service delay and wherein the service delay is calculated based upon a blocking probability.
