Abstract

The present disclosure provides a network slicing configuration method, device, and storage medium, wherein the method includes: establishing a SFP path set, determining the mapping sequence of SFPs according to path length information and delay index information, and sequentially assigning each path according to the direction of data transmission The virtual nodes in the SFP establish a candidate physical node set; after each candidate physical node in the candidate physical node set is mapped by the virtual node, calculate the actual delay of the physical link corresponding to the formed virtual link, and select the candidate physical node The node performs virtual node mapping of the SFP. The method, device, and storage medium of the present disclosure provide a network slice deployment and configuration scheme for services with end-to-end data transmission delay constraints; when mapping virtual nodes on the path sequentially according to the data transmission direction, the front and rear virtual nodes are analyzed. The mapping status of the nodes, combined with the topological information of the physical nodes to select the mapping target, improves the utilization efficiency of physical resources.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a network slice configuration method, device and storage medium. Background technique [0002] 5G network slicing technology maps the virtual network corresponding to the service to the underlying physical network. 5G networks support multiple vertical services with different performance requirements. Network slicing technology enables operators to segment multiple virtual end-to-end networks from one underlying physical network to provide differentiated service guarantees for different services. A class of mainstream services on mobile networks, such as video transmission services and content distribution services, have clear requirements on the delay of data transmission. However, the prior art does not provide how to allocate underlying physical resources for deployment of network slices containing multiple Service Function Paths (SFP) with end-to-end delay...
