mpls backbones and qos enabled networks interoperation
It is believed that in the future the telecommunication and data networks will be integrated into one single network, based on IP switching. One of the technologies that certainly will be adopted in the core of this new network is MPLS. Together with MPLS, other QoS architectures, such as IntServ and DiffServ will be used. As a result of this, a framework that allows the interoperability of the different existing architectures is needed. In this paper, an integration model based on MPLS and DiffServ is presented. The model was tested in the ns2 simulator and the results certify its applicability as the presented model showed better performance in all analyzed QoS parameters: delay, jitter, packet loss and bandwidth.
