There has been a rapid traffic volume increase in packet switched networks due to the recent data communication growth. Consequently, the ease with which networks are capable of expanding to keep pace with this increase has become an important consideration. In this paper, a comparison is made of the hierarchical and non-hierarchical network configurations which may serve as possible methods for readily accommodating this increasing network expansion. A special developed simulation providing essential simulation analyses confirms that the hierarchical network offers the most promising approach to this problem from the viewpoints of cost effectiveness and network maintenance.
