The invention provides a FlexE-based resource allocation method and system. The method comprises the following steps: acquiring flow data of different slice services in each service type; according to historical traffic and current traffic data of the slice service, predicting a traffic change period of each slice service, and for a service needing to be monitored in real time, calculating an allocation bandwidth in real time; and setting a weight factor for each service type, calculating a product value of the weight, the time delay and the actually allocated bandwidth of each service, and allocating the bandwidth according to the sequence of the product values. According to the invention, based on FlexE slice discrete resource dynamic allocation, a multi-service multi-slice scene is considered, a monitoring period list is established, so that different slices have different monitoring periods, a discrete bandwidth actually required to be allocated is obtained based on actual traffic arrival and time delay d
