Adaptive bandwidth allocation schemes for lightwave LANs with asymmetric traffic

The bandwidth of a WDM star network that operates under asymmetric traffic must be allocated in such a way that each station takes a portion of the network bandwidth proportional to its needs. A dynamic bandwidth allocation scheme is presented. The proposed scheme is based on the network feedback information in order to be capable of adapting to the changing traffic characteristics. According to the proposed scheme, a set of learning automata processes the network feedback information and dynamically allocates the available bandwidth to the stations according to their needs.
