The invention provides a centralized resource information synchronization method and equipment based on a hybrid grid optical network. Wherein the hybrid grid optical network comprises fixed grid nodes and flexible grid nodes; the method comprises the following steps: collecting network resource information of all nodes in a network by using a routing module, and sending the network resource information to a path calculation module; sending the network resource information to a traffic engineering database for storage through a path calculation module; and in response to the change of the target node, synchronizing the change information of the target node into the network by using the routing module, and updating and storing the change information into the traffic engineering database through the path calculation module. The traffic engineering database performs real-time updating according to the change of the resources in the network, and the information does not need to be flooded among the nodes of the n
