Adaptive connection admission and flow control: quality of service with high utilisation
(IEEE, 1994)In this paper, we use adaptive feedback and adaptive feedforward control methodologies to avoid congestion at high server utilisation. This addresses the combined connection admission and flow control problem (generic ...

Adaptive nonlinear congestion controller for a differentiated-services framework
(2005)The growing demand of computer usage requires efficient ways of managing network traffic in order to avoid or at least limit the level of congestion in cases where increases in bandwidth are not desirable or possible. In ...

Content-selection strategies for the periodic prefetching of WWW resources via satellite
(2001)In this paper we study satellite-caching, that is, the employment of satellite multicasting for the dissemination of prefetched content to WWW caches. This approach is currently being deployed by major satellite operators ...

Fuzzy backward congestion notification (FBCN) congestion control in asynchronous transfer mode (ATM) networks
(IEEE, 1995)In this paper, we study the performance of a fuzzy control scheme as a first step to develop better control strategies for avoiding congestion and attaining high link utilisation in ATM based networks. Due to the complexity ...
