Abstract
A traffic generator (TFG) is provided for generating a packet information stream (OUT) with predetermined characteristics based on individual characteristics of a plurality of traffic sources (S0-255, G240-241). Such a traffic generator is used in an Asynchronous Transfer Mode or ATM networks and thus plays an important role in the emergence of such networks. The traffic generator includes a generation memory (GT) for storing a series of individual data (Group A-E) related to traffic sources (S0-255, G240-241), and includes a generation circuit (GM) for cyclically reading a series of individual source related data. Each of the individual source related data (Group A-E) relates to at least one of the traffic sources (S0-255, G240-241) as well as to generation decision data (GD, GEOT) associated thereto. Based on its associated generation decision data (GD, GEOT), the generation circuit (GM) determines whether a packet is to be generated for the at least one traffic source (S0-255, G240-241) or not, and generates an idle packet if no packet is to be generated for the at least one traffic source (S0-255, G240-241). The generation decision data (GD, GEOT) eliminates the need to run a complicated and time-consuming algorithm for calculating a new series of individual source related data every time the actual bit rate of one of the sources is updated.
