Traffic generator.

摘要

A traffic generator (TFG) for generating a packet information stream (OUT) with predetermined characteristics based on individual characteristics of a plurality of traffic sources (S0-255, G240-241) is proposed. Such a traffic generator is an essential test tool for 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) storing a series of individual data (Group A-E) related to said sources, and a generation means (GM) to cyclically read said series of individual source related data. Each of said individual source related data (Group A-E) relates to at least one of said sources (S0-255, G240-241) as well as to generation decision data (GD, GEOT) associated thereto. The generation means generates for this one source based on its associated generation decision data. Thanks to the generation decision data it can be avoided that a complicated and time-consuming algorithm for calculating a new series of individual source related data needs to be run every time the actual bitrate of one of the sources is updated.
