Abstract

The invention provides a network slice virtual resource allocation method, system and device. The method comprises the following steps: acquiring a physical network topology structure and a network slice service chain network thereof; determining all possible mapped physical nodes, propagation links and propagation time delay thereof according to the network topology structure and the network slice service link flow thereof; and determining a constraint condition according to the physical node, the propagation link and the propagation delay, and performing path screening on the physical node and the propagation link according to the constraint condition to obtain an optimal mapping physical node and an optimal mapping link path. By implementing the method and the device, the network communication capacity limitation and the ultra-low time delay performance requirement limitation are comprehensively considered, so that the time delay of network communication transmission can be reducedand the network slice virtual resources can be allocated under the condition of the maximum network communication capacity.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method, system and device for allocating network slice virtual resources. Background technique [0002] In the 5 network, business scenarios present the characteristics of diversification and differentiation. In order to support the requirements of various services, use cases, and business models ranging from high-throughput services to delay-sensitive services, network slicing will build multiple logically independent end-to-end virtual networks according to requirements, relying on the allocation of necessary physical resources. Provide one or more network services flexibly for a given business scenario. [0003] Among them, ultra-low latency is an important performance index that needs to be met by 5G transport network slicing. In the case of meeting ultra-low latency requirements, allocating physical resources suitable for performance requirements for network s...
