AI Technical Summary
Technical Problem
In hierarchical networks, existing technologies cannot effectively achieve load balancing across the entire network, resulting in congestion in upper-layer network links.
Method used
By obtaining traffic forecast information for each time period, the target forwarding path that meets the path planning objectives is planned, including link bandwidth limitation and load balancing. Local adjustment and adaptive update mechanisms are used to optimize path planning.
Benefits of technology
It achieves load balancing of the entire network link, reduces network congestion, and improves the quality of service forwarding paths and network stability.

Abstract
The present application relates to the technical field of communications, and discloses a path planning method and apparatus, a device, a system, and a storage medium. The method comprises: acquiring traffic prediction information respectively corresponding to at least one time period; and on the basis of the traffic prediction information respectively corresponding to the at least one time period and at least one selectable path respectively corresponding to each service, determining a target forwarding path of each service meeting path planning objectives. The path planning objectives comprise: the service traffic borne by any link in a hierarchical network in any time period is less than or equal to the bandwidth capacity upper limit of any link, load balancing is realized between multiple links connected to a same network node in the hierarchical network, and the transmission quality of the target forwarding path of any service meets a quality requirement of any service. Path planning of a global service is realized, network link congestion can be reduced, and better effects that load balancing between all network links is realized and a service forwarding path meets a service quality requirement are achieved.
