This solution improves the network transport performance by overcoming the limits imposed by a transmission control protocol/Internet protocol (TCP/IP)-based stack suite, while maintaining the interfaces offered by it. This is an important issue since TCP/IP is widely used and most of the applications are based on it. The

A number of pricing models have been proposed and analyzed in the context of Quality of Service (QoS) guaranteed networks (e.g.,

The reference allocation algorithms considered are based on multi-objective programming (MOP) and are called "Utopia minimum distance" (UMD), "constrained Utopia minimum distance" (CUMD) and "QoS point minimum distance" (QPMD). The rationale under the algorithms is considering bandwidth

The basic idea of this work is that a resource allocation algorithm where the allocation function is conscious of the difference may result more efficient. To

In particular, it shows the analytical approximation of the round trip time (RTT) of a TCP connection and defines a bandwidth asymmetry index, which is the key point of the work. The final goal
