The embodiment of the invention provides a service scheduling method and device for a cross-domain computing power network, equipment and a storage medium, and relates to the technical field of
network communication. The method comprises the following steps: splitting a service request into sub-services, generating a service unloading constraint set and a link resource constraint set, generating a target function according to node resource cost and
total delay corresponding to the sub-services allocated to physical nodes, forming an
optimization problem according to the service unloading constraint set, the link resource constraint set and the target function, and for each sub-service, generating a link resource constraint set according to the
optimization problem. And determining an initial computational domain based on user position information corresponding to the service request, solving an
optimization problem in the computational domain to obtain the allocated physical nodes corresponding to the sub-services, otherwise, selecting a new computational domain from the corresponding hierarchical set for solving until the allocated physical nodes corresponding to all the sub-services are obtained. And by adopting a strategy of combining sub-service splitting with dynamic selection of the computational domain, the risk of
information leakage is reduced, and meanwhile, the service scheduling efficiency of the cross-domain computing power network is improved.
