The capacity of the resources is limited, and if the user demands exceed the
capacity, the network becomes ’congested’. The congestion causes a degradation
in system performance. In interconnected networks there are two classes
of traffic within a network. One class is the local traffic that is generated and
transmitted within the network. The other class is the internetwork traffic
transmitted to or from other networks. In this thesis, the effect of internetwork
traffic on the performance of a network is investigated. Computer
simulation of an interconnected network model is provided in order to evaluate
the effectiveness of a window-based congestion control mechanism on
preventing congestion in gateways and in attached networks caused by the
overload of internetwork traffic. Also two dynamic window congestion control
algorithms are provided and studied. These algorithms provide further
control to window mechanism by adjusting the window size in accordance
with the availability of the network resources at the destination. Dynamic
algorithms are evaluated comparing them with static window control.Ulusoy, ÖzgürM.S
