Performance of Rate-Based Control Method Using ERPCA
نویسندگان
چکیده
Rate-based congestion control is effective and still simple for traffic management in ATM networks. As one of practical realization schemes, Enhanced Proportional Rate Control Algorithm (EPRCA) is recently proposed in ATM Forum. The main purpose of this paper is to analyze the performance of EFCI switch, which is an essential one suggested in EPRCA. First, we provide an analytic model for EPRCA with homogeneous traffic sources and a single bottleneck ATM link. Then, we obtain performance measures in terms of the maximum queue length at the switch and its throughput by utilizing the first order fluid approximation method. We provide suggestive equations for parameter tunings of EPRCA and show some numerical examples. 英文 key words ATM Network, Rate-Based Congestion Control, EPRCA, EFCI Switch, Steady State Analysis

Perfect Tracking of Supercavitating Non-minimum Phase Vehicles Using a New Robust and Adaptive Parameter-optimal Iterative Learning Control
In this manuscript, a new method is proposed to provide a perfect tracking of the supercavitation system based on a new two-state model. The tracking of the pitch rate and angle of attack for fin and cavitator input is of the aim. The pitch rate of the supercavitation with respect to fin angle is found as a non-minimum phase behavior. This effect reduces the speed of command pitch rate. Control...

Increase of employment and reduction of unemployment are the most important indicators for community development. Statistical indicators derived from the implementation of the Labor Force Survey design are useful in evaluating employment policies and performances. But, it should also emphasize that using an indicator (such as the unemployment rate) alone cannot be a suitable criterion for asses...
