METHOD AND DEVICE FOR ACQUIRING ROUTE OF SOFTWARE-DEFINED NETWORK AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/218649
Kind Code:
A1
Abstract:
Disclosed are a method and device for acquiring a route of a software-defined network (SDN) and a storage medium, in which the SDN is formed by at least two sub-domains. The method comprises: in response to a received request to acquire a route of an SDN, initializing the SDN; updating a node status of each sub-domain in the SDN, wherein the node status comprises at least: a node mileage of a node and a previous-hop node of the node; extracting, on the basis of the updated node status of each sub-domain, a shortest route in each sub-domain; and connecting the extracted shortest route of each sub-domain to acquire a first shortest route of the SDN. According to a service type, after the weight of an SDN link is reconfigured, a second shortest path can be acquired in the same manner, and a pair of shortest cross-domain separation paths can be acquired by deleting an overlapping link on the first shortest path and on the second shortest path.
