• Resumen

  • This article provides a performance evaluation between DiffServ and IntServ, two computer architectures that allow the implementation of quality of service (QoS) to a given network. A simulated scenario in NS2 is proposed and the two types of QoS are implemented to evaluate variables such as jitter, bandwidth, delay, and packet loss, all with the aid of graphs and with statistical results.First, the simulation is done without implementing QoS; subsequently, IntServ and DiffServ are implemented to compare between the two architectures and define the advantages and disadvantages of each type of service and determine the most appropriate for a specific program.
