MPLS-based QoS interworking among wide area subsystems

This paper deals with a novel protocol architecture to interconnect autonomous systems (ASes), together with guaranteeing the QoS provision. The adoption of the MPLS protocol allows defining an effective way to face the heterogeneity due to the interconnection of ASes implementing different QoS technologies. In this view, the problem regarding the management of the traffic flows that cross the boundaries of the ASes reveals to be a hot topic of research and will be deeply investigated in the paper.
