Characterisation of Singapore one ATM network

The statistics of cell loss at both burst and cell levels are studied by si mulation based on the configuration of the Singapore One ATM network. A vir tual connection through the Singapore One network is modelled as a tandem q ueueing network to which mixtures of homogeneous discrete-time burst-silenc e traffic with different burst lengths are offered. Attention is focused on a designated traffic stream as it goes through the tandem queueing network . in the simulation, the authors have not introduced the 'independence assu mption' between the adjacent queues, i.e. the actual tandem queueing networ k is used to obtain the performance measures for the designated traffic str eam. Cell loss probability and high-order cell, loss distributions such as cell. lass-free run distribution and cell loss pattern distribution are obt ained. These results provide valuable information for the estimation of end -to-end overall quality of service (QoS), design of the cell policing mecha nism and flow control schemes in the ATM networks.
