exposes the main contribution of the Thesis. The window bounded D/D/1/W model and Window-Time (WT) plane are defined. On this basis, a new Window-Time-Space flow control (WTFC) is developed, which enables the transmitter to estimate its optimal packet sending rate and window, under condition that total network (path) capacity is known. Simulation measurement results are presented and analyzed.

describes the introductory definition of the heterogeneous networks expected to be dominant in the near future, consisting of Ethernet LANs interconnected through the worldwide public ATM network. The main conclusion is in favour of end-to-end transport layer flow control, which is independent of the underlying network structure and keeps user data out of the network.

verifyes the use of the D/D/1 queuing model in the flow control field. It is concluded that actual traffic bursteness is not only a result of the natural user behaviour, but also of the interaction between the flow control algorithm used and the network dynamics. It is shown that lowering the variance of the packet interarrivals by one order of magnitude (traffic shaping) gives the response curves of G/G/1 model which are close enough to the D/D/1 ones. This is later used to derive the D/D/1/W model and the WT (Window - Time space) flow control algorithm.

describes the extensions to the NS-1.1 LBL Network Simulator with ATM virtual channels. Although not actually the part of the Thesis, this extension was used in the experimental part of the research. The article contains a breef comparison of TCP (RWIN limited) and WT flow control algorithms
