This article presents the results obtained by modeling the performance of a core IP/ATM network compared to a CRLDP/IP/MPLS network when carrying delay sensitive traffic (videoconferencing) with minimum resource reservation guarantees and optimal interaction between user and applications. In order conduct the experiments, OPNET-modeler simulation software (educational version) was used, which encouraged alternative implementation features that help decide which of the two technologies represents a suitable solution for current networking problems, where large volumes of information need to be transmitted and the QoS offered to average users is pretty poor.
