A Hardware Implementation to Emulate Traffic Characteristics Based on Timed Automata Models
In realtime networkstraffic characteristic with burstiness constraints is one of the key QoS (Quality of Service) factors in the worst case.Using timed automata to model the traffic can reflect the uncertainty under the constraints by arrival curves.We adopted hardware description language to describe timed automata formal modelsand studied correspondence between hardware logic and timed automata model.The method took the advantages of programmable array chipsfully represented the concurrent behaviors between timed automataand then implemented the hardwareintheloop testing and detection.With such a methodwe simulated the virtual link traffic generation in realtime network.Some typical test results indicated that the model can constrain the traffic characteristics of virtual linkwhich proves the feasibility of the hardware implementation method.
