摘要： Provided is a rerouting method. The method includes: updating network slice information based on service information of an affected service, wherein the service information includes service bandwidth resources, and the network slice information is information of one or more network slices obtained by dividing a topology of an original network; obtaining a network slice index of the affected service based on the service information of the affected service and the updated network slice information, wherein the network slice index is a correspondence between the affected service and the network slice; and determining a new route for the affected service based on the affected service and the network slice index. The rerouting method has the advantages of short time consumption, high efficiency and high success rate when performing rerouting. A rerouting apparatus, an electronic device, and a computer readable medium are also provided.
