In this paper, we propose, verify, and evaluate a method combining cross‐layer method and bandwidth allocation to overcome the difficulty of flow control in a network with large bandwidth delay product. When the bandwidth delay product is large, there are problems with the convergence time, efficiency and stability of bandwidth utilization, and fairness among traffics of different round‐trip time...
The authors are studying backward simulators which trace from results to causes for comprehensive verification of system safety. It is not easy to make a backward simulation model because the forward model may not be expressed in a reversible formula, or it is not reversible in cases of multiple inputs or inclusion of internal state variables. In this paper, we propose a backward simulator which can...
To verify the safety of a system, it is desirable to test all the situation, at least, by simulation. However, it is difficult to test the entire situation because the number of situations is almost uncountable. As a promising method, backward simulation which traces back from the undesirable result to causal input(s) is proposed. For such backward simulation, we have to transform the forward model...
In recent years, various network devices have been provided by many vendors. Therefore, administrators must have knowledge of those network devices and network technologies when to design, configure and monitor their networks. To reduce administrative cost, we proposed Network Description Language (NDL) for network lifecycle (design, configuration and monitoring) managements. The administrator only...
Currently, power savings are strongly requested. We propose a method for power savings that considers the characteristics of appliances by using appliance classes and power margin of individual appliance by using bidirectional communications. In this paper, we show the mechanism, implementation and the results of verification experiments.
Optical long distance and high speed networks require an effective flow control scheme better than the ordinary TCP. In this paper, we examine two cross-layer flow control schemes, XCP and XLBA especially for short burst flows. Cross-layer flow controls are essential means to optimize bandwidth utilization and fairness without severe control instability. We are proposing XLBA which eliminates feedback...
