Abstract

Simple integrated media access (SIMA) is a new service category for packet based communications systems, such as ATM or IP. SIMA offers a simple way to introduce easy charging, real time support and increase in the capacity of networks. According to the SIMA concept each customer shall define only two issues before a connection establishment: a nominal bit rate (NBR) and the selection between real-time and non-real- time classes. NBR forms the basis of charging and defines how the network capacity is divided among different connections during overload situations. The ratio of momentary bit rate of the source and NBR defines for each individual cell a priority level that is used to select the cells to be discarded under congestion. Simulation results are described about the cell loss as a function of priority level of a cell. SIMA can be also be equipped with a priority feedback system that informs traffic sources about the condition of the network. Results on the performance of sources using this information are published. This paper also presents some simulations on a SIMA network that uses packet discarding. Simulations presented in this paper show that SIMA is capable of fulfilling requirements for the future broadband Internet networks.
