Effects of an extra link and routing on spatio-temporal packet traffic dynamics of network model

The spatio-temporal packet traffic dynamics of data networks is highly heterogeneous and unpredictable. Understanding these dynamics is of vital importance for their future development. Some of the aspects of these dynamics can be captured and investigated by studying simplified models of packet switching networks. Our model describes processes taking place at the network layer of the OSI Reference Model. We describe briefly the model used to study the spatio-temporal packet traffic dynamics for various routing cost metrics and traffic loads presented to the network. We investigate how an additional link added to a network connection topology affects the spatio-temporal packet traffic dynamics. We present a variety of simulation results and analyze them.
