Abstract
A method for calculating a shortest path, a routing acquisition device, a server and a non-transitory computer-readable storage medium are disclosed. The method may include: acquiring resource information for a network according to a received routing request, where the routing request includes a start node, an end node, a service constraint, and an obligatory constraint; calculating service constraint weights for topological elements in the network according to the service constraint, and calculating obligatory constraint weights for the topological elements according to the obligatory constraint and the resource information for the network; and calculating, according to the service constraint weights and the obligatory constraint weights for the topological elements, a shortest path from the start node to the end node that satisfies the obligatory constraint.
