In order to improve the lack of flexibility in traditional network routing and forwarding systems, an open architecture OpenTDR scheme was proposed. This solution combined two-dimensional routing and software defined network (SDN), which could implement different traffic balancing mechanisms and energy saving mechanisms in different time periods. The experimental results show that upgrading from one-dimensional to two-dimensional routing and forwarding mode, combined with the centralized global planning approach of SDN, can make the flow control and service quality of networks (especially wide area networks) more flexible, and achieve the goal of traffic balance and save energy consumption. On the other hand, two-dimensional routing can be compatible with traditional routing, which also provides a suitable transitional solution for SDN transformation based on traditional networks.
