Measurements driven traffic technologies in ATM networks

This paper describes new traffic technologies in ATM networks called Measurement Driven Traffic Technologies. Existing traffic technologies estimate performance according to various assumptions about traffic characteristics and perform traffic control and dimensioning on that basis. In future networks, however, it will be impossible to perform traffic measurement that can describe traffic characteristics completely for the variety of traffic characteristics. It will be questionable that we can make likely assumptions about such traffic. This paper proposes measurement driven traffic technologies to control and design networks on the basis of ordinary traffic measurement items and incomplete information on traffic characteristics, minimizing assumptions. In particular, it describes the relationship between the number of cells and the cell loss ratio, Bayesian performance estimation based on monitored performance, and an operation system that applies the proposed technologies while reducing the length of the operation cycle.
