The invention discloses a robust routing and channelizing system and method in an optical network based on a symmetrical hose tube model, and belongs to the technical field of communication network. The system comprises an initialization module, a robust routing module and a robust channelizing module. The channelizing method comprises the following steps: 1, constructing an optical network; 2, calculating a network load allocation vector; 3, translating into a three-dimensional volume of a business channelizing matrix; 4, constructing a virtual topology; and 5, continuously channelizing the left service from the step 4 into the constructed optical circuit on the constructed virtual topology of the step 4. The robust routing and channelizing system and method in the optical network based on the symmetrical hose tube model has the advantages that the energy efficiency of the network route is improved; the energy consumption of an optical transceiver consumed by mobile X-ray system withhigh frequency (MXHF) is lower, more energy consumption of a routing terminal is saved, smaller channelizing energy efficiency factor is provided, thereby improving the network channelizing energy efficiency.
