Abstract
The present invention concerns an apparatus for evaluating the quality of service in a network. The QoS evaluation apparatus includes an arrival detection section to provide a timestamp to a specific processing unit included in a packet that arrives at an attention point in the network and is branched off by duplicating from a switching system. An estimation section estimates the arrival times of the plurality of processing units arriving at the attention point, and a simulation section simulates arrival times corresponding to the estimated arrival times at the attention point, produced by the arrival time estimation section, according to a pre-determined logic equation.
