A nonlinear ABR flow control with feed-forward compensation for ATM networks
Abstract
The problem of flow control in fast, connection oriented communication networks supporting traffic generated by multiple sources is considered. The network is modelled as a dynamic system with different delay times. A nonlinear strategy governing the behaviour of the sources is proposed. The strategy combines Smith principle and feed-forward compensation with the conventional relay type controller. The strategy guarantees no cell loss and full bottleneck link utilisation in the controlled network. Furthermore, the feed-forward compensation helps to achieve better quality of service in the controlled network.
