In order to solve traffic unbalancing caused by up/down routing for irregular networks, two-dimensional direction is introduced into a spanning tree, and novel routing algorithms based on two-dimensional turn model are proposed. The proposed algorithms improve traffic balancing by selecting prohibited turns for deadlock-free carefully. Simulation results demonstrate that proposed algorithms improve both the performance and stability.
