Minimum price inter-domain routing algorithm

We show a minimum price (MP) inter-domain routing algorithm that selects the cheapest paths among a number of independent domains, used for supplying end users with application services. The price of the network service is determined by the so-called service parameters and network parameters. The former represents the negotiable quality of service (QoS) parameters, summarized by the so-called virtual end-to-end delay, and the latter characterizes the intrinsic quality of the network.
