Problems solved by technology

However, realizing the isolation between network slices will bring certain resource utilization problems. In order to achieve network slice isolation, it is necessary to create more dedicated virtual machines and wavelength connections to ensure the independence of network slices and reduce the utilization of network resources. efficiency

Embodiment Construction

[0072] The next generation of mobile communication (5G) proposes three types of application scenarios for future mobile applications: capacity-oriented (eMBB), ultra-reliable and low-latency (uRLLC) and ultra-large-scale connection (mMTC). It can provide key technologies for different application scenarios, run multiple logical networks on a common physical infrastructure, and allocate different topologies, bandwidth and computing resources to these logical networks, so as to provide support for different types of services and meet different needs. There will be a large number of different types of service requests in the future mobile network, such as high-definition video live broadcast, high-definition online games, autonomous driving and other business forms that have different requirements for delay, bandwidth and reliability in the network. A slice is an independent virtual network established to satisfy a class of requests with similar service types. Since it is a type ...

Abstract

The invention provides a network slice mapping method and device, a server and a storage medium, and the mapping method comprises the steps: calculating a comprehensive evaluation index of a physicalnode in a physical network according to the type of a network slice; determining the processing capacity and bandwidth required by the network slice to be mapped; and according to the comprehensive evaluation index of each physical node, establishing mapping of the network slice by taking the minimum number of open nodes and / or the minimum number of established wavelengths as a target. The mappingprocess of the 5G network slice is established with the minimum number of open nodes and the minimum number of established wavelengths as the target, the 5G network slice mapping method based on isolation is provided according to the isolation mechanism of the network slice, and processing and bandwidth resource consumption is lower based on the mapping method.

Description

technical field [0001] The present application relates to the technical field of the Internet, and in particular to a network slice mapping method, device, server and storage medium. Background technique [0002] In the communication network before the 5G (5th generation mobile networks or 5th generation wireless systems, 5th-Generation, fifth-generation mobile communication technology) mobile communication era, the goal of the mobile communication network is large capacity, high speed, wide coverage, for mobile User equipment provides high-quality data and call services to ensure the service quality of each user. In the current communication network, different types of mobile user equipment have different requirements for mobile service quality, and different mobile user equipment have differentiated requirements in terms of data rate, end-to-end delay, and reliability. [0003] In the 5G era facing the Internet of Everything, mobile services are divided into three categor...
