Downward communication is a popular push-based scheme to forward messages from headquarters to front-line staff in a large-scaled company. With the maturing intranet and web technology, broadcasting algorithms, including pull-based and push-based broadcasting algorithms, it is feasible to send downward messages through web-based design by sending packets on(More)
We propose a precomputation-based scheme which offers Pareto optimal solutions to the network dimensioning problem. This scheme is performed by means of a two-phase procedure. The first phase precomputes paths for a wide range of possible constraints, while the second phase selects an adequate path through a simple procedure. That is, the first phase(More)

We present an integer programming approach to offer optimal bandwidth allocation and QoS routing for network management problems with heterogeneous service classes. The bandwidth allocation policy in such communication networks is determined in accordance with the proportionally fair rule, which can be expressed by utility functions of network users. The(More)
