Virtual network resource allocation method with high reliability and load balance

Abstract

The invention discloses a virtual network resource allocation method with high reliability and load balance. A vEPC and a network link is included, and the vEPC virtualizes basic hardware equipment into universal network resources; according to the resource allocation method, basic hardware resources in universal network resources are used as an underlying network, the virtual service carried by the underlying network is called as a virtual network; the basic hardware resources in universal network resources are used as the underlying network, the underlying network is divided into communitiesand the communities are optimized; the underlying network and the virtual network are sorted; and finally, resources are allocated to the virtual network. The method comprises two processes of allocating resources to virtual nodes and allocating resources to virtual links, load balance and reliability are guaranteed when the resources are allocated to the virtual nodes, bandwidth requirements ofa virtual network are guaranteed when the resources are allocated to the virtual links, and the problem of large-scale virtual network resource allocation of a 5G core network is effectively solved.

Description

technical field [0001] The invention relates to the field of network resource management, in particular to a virtual network resource allocation method with high reliability and load balance. Background technique [0002] With the rapid construction and application of 5G networks, emerging services such as 5G-based smart life, smart factories, and unmanned driving have gradually begun to land. In order to ensure the service quality of various emerging services, the construction of the core network of 5G networks is particularly important. Currently, the virtualized Evolved Packet Core (vEPC) has become the basic architecture of the 5G core network. By introducing virtualization technology, vEPC technology realizes the slicing function of the 5G core network, effectively improving the utilization rate and reliability of network resources. Using vEPC technology, the original basic network is divided into the underlying network and virtual network. The underlying network is r...
