According to the requirements of novel electric information and communication network, dynamic routing and wavelength assignment strategy with its effect on ICT network performance is addressed, and a heuristic algorithm based on hierarchy graph model is proposed to solve the dynamic centralized routing and wavelength assignment problem. Without rerouting, selecting available light channel count integrating with hop number as the link optimizing goal, the connection request is established on the lightpath with most available channel number and less hop number, so as to achieve load balance and reduce the occupation of network resource as less as possible. Simulating results show that the algorithm performs better than the other existing algorithms from the viewing of decreasing blocking probability.
