摘要: A switching unit (1) for the through of different types digital data in asynchronous transfer mode, a so-called ATM-switch, is to be tested whether it able overcome specific load. The installation provides feedback (4) from outputs (2) inputs (3) baseload cells, which are fed by generator (5) an input (35), and constantly circulate because their routing information. also emits test cells (35). chooser or discriminator (6) connected measuring output (21) feeds back (41) (31). read, change, copy suppress certain contents cells. It routs and/or second analyzer (7), evaluates them statistically. Load testing such unit, can handle load, may cause instabilities switch, as uncontrolled cell loss, congestion, errors like. inventive method load switch has two stages. In first stage, supplied successively controlled manner until base near specified reached. flow this altered rerouting individual superimposing way, any that occur result overload immediately brought under control.
