PATH PLANNING METHOD AND CONTROLLER

摘要

The present application provides a path planning method and a controller. The method includes: acquiring data flow information of a to-be-transmitted job in a software-defined network, where the job includes at least one target data flow, and the data flow information of the job includes: a source address, a destination address, and a volume of each target data flow; and performing path planning according to the data flow information, and obtaining a job transmission path used to ensure that the job is transmitted in the software-defined network in a shortest job transmission time, where the job transmission path includes a transmission path corresponding to each target data flow in the job. The present application improves a data transmission speed of a job in an SDN network.

主权项

1. A path planning method, comprising:
acquiring data flow information of a to-be-transmitted job in a software-defined network (SDN), wherein the job comprises at least one target data flow, and the data flow information of the job comprises a source address, a destination address, and a volume of each target data flow; performing overall path planning on the to-be-transmitted job according to the source address, the destination address, and the volume of each target data flow in the data flow information of the job, wherein the overall path planning comprises simultaneously planning a transmission path corresponding to each target data flow comprised in the to-be-transmitted job; and obtaining a job transmission path over which the to-be-transmitted job is transmitted in the software-defined network in a shortest job transmission time, wherein the job transmission time is a time needed to complete transmission of the job in the software-defined network, and the job transmission path comprises the transmission path corresponding to each target data flow in the job.
