This situation causes a lot of waste of resources. The growing bandwidth demand puts large pressure on the transmission network, so it is necessary to increase the utilization of idle backup circuits. In this paper, we propose a survivable network design with capacity sharing between IP and wavelength service. An efficient heuristic approach is presented. This approach allocates the idle backup wavelength circuit to the IP network while ensuring the survivability of the IP net- work. We observe that sharing idle backup circuits with IP traffic enables higher resource utiliza- tion. The approach ensures its survivability while reducing network cost.
