BANDWIDTH INCREASING AND REDUCING METHOD AND APPARATUS, STORAGE MEDIUM, AND ELECTRONIC APPARATUS

A bandwidth increasing or bandwidth reducing method and apparatus, a storage medium, and an electronic apparatus are provided. The bandwidth increasing method includes: acquiring, by respective nodes, a slot increase request according to a first specified rule, wherein the slot increase request is used for instructing the respective nodes to start a slot adjustment of a section layer within a predetermined period of time; in a case where the respective nodes are capable of processing the slot increase request, sending, by the respective nodes, a slot increase confirmation message according to a second specified rule; increasing, by the respective nodes, first slots of the section layer between every two nodes in the respective nodes based on the slot increase confirmation message; after the increase of the first slots of the section layer is completed, increasing, by the respective nodes, a bandwidth of an entire path layer corresponding to the respective nodes. The technical solution solves the problem that in the metropolitan area transport network, the lossless adjustment of the bandwidth cannot be realized, and the bandwidth adjustment manner is not perfect in the related technology.
