A large flexible array of nonlinear service processing elements, which capture the functional characteristics of the signalling mechanisms of switching nodes in asynchronous heterogeneous networks (e.g. broadband ISDN), has been designed and implemented. The array is based on field programmable gate arrays and allows a wide range of network configurations and conditions to be explored at low cost with different types, numbers and arrangements of processing elements and architectures. The array provides a rapid and flexible way of studying the service dynamics of large arrays of interconnected multi‐processor systems, under normal and abnormal service loading conditions. It also allows integration issues, stability criteria and fault tolerance in the co‐ordination and control of asynchronous distributed heterogeneous networks to be investigated. Initial studies using the array have confirmed the existence of various behaviours (e.g. chaos, persistent oscillations) seen in real telecommunication systems. © 1997 by John Wiley & Sons, Ltd.
