Abstract: Hierarchical traffic control is a promising approach for improving scalability in the face of network size. In this scheme, multiple controllers are introduced in a network, and these hierarchically decide operations. At the bottom layer, controllers decide specific operations in a small area, while the controllers at the upper layer decide inter-area operations using abstracted information from the lower layers. These controllers depend mutually on controllers in other layers, which may cause control oscillations, disturbing the appropriate ne...
