However, it has Computer simulation modelling has the advantage of flexibility and modelling accuracy. However, it has limitations in its ability to be used to simulate cell loss rate when deriving t limitations in its ability to be used to simulate cell loss rate when deriving t limitations in its ability to be used to simulate cell loss rate when deriving t limitations in its ability to be used to simulate cell loss rate when deriving t required for data services to guarantee specific Quality of Service (QoS) requirement. Cell loss rates are required for data services to guarantee specific Quality of Service (QoS) requirement. Cell loss rates are required for data services to guarantee specific Quality of Service (QoS) requirement. Cell loss rates are required for data services to guarantee specific Quality of Service (QoS) requirement. Cell loss rates are simulated with excessive and unacceptable computer simulation run times. This limitation was overcome simulated with excessive and unacceptable computer simulation run times. This limitation was overcome simulated with excessive and unacceptable computer simulation run times. This limitation was overcome simulated with excessive and unacceptable computer simulation run times. This limitation was overcome in an earlier publication in an earlier publication in an earlier publication in an earlier publication by the author using an integrated simulation technique. This paper, therefore, by the author using an integrated simulation technique. This paper, therefore, by the author using an integrated simulation technique. This paper, therefore, by the author using an integrated simulation technique.
