This paper presents the results of a transmission quality study in a network with a DiffServ architecture. The impact of differentiated services based on traffic prioritisation was studied. A carrier network model in a differentiated servicesarchitecture with traffic prioritisation was designed and tested. The operator network used the OSPF protocol, while the client networks communicated using the EIGRP protocol. Different traffic classes in the queueing systems were studied, influencing delay and delay variation. Traffic generated with Exfo FTB-860 test equipment was introduced into the designed network. The measurement equipment used supported the ITUT Y.1564 measurement methodologies. The transmission quality was tested according to the EtherSAM methodology and carried out in bidirectional mode. The tests carried out showed the influence of different data lengths on the quality of transmission in the test network. The results proved that the correct implementation of QoS mechanisms in the network makes it possible to ensure the required quality of service. It was shown that for delay-sensitive traffic which fluctuates beyond its nominal speed, queuing systems allow transmission quality to be achieved with guaranteed bandwidth and delay.
