Description
Technical Field
The invention belongs to the technical field of communication, and particularly relates to a network slicing method for network equipment without virtualization capability, a system and a storage medium thereof.
Background
The network slice is to divide a physical network into a plurality of mutually independent virtual networks through a virtualization technology, each virtual network is called a network slice, and network functions in each network slice can be arranged to form a complete instantiated network architecture through dynamic network functions after customized cutting. By creating different network slices for different services and communication scenes, a network can adopt different network architectures and management mechanisms including reasonable resource allocation modes, control management mechanisms and operation strategies according to different service characteristics, so that the performance requirements in the communication scenes are ensured, the user experience is improved, the efficient utilization of network resources is improved, for example, a localized control management mechanism and a data transmission mechanism are introduced in an ultra-dense scene, and the signaling overhead and the hop count of a transmission path in the network are reduced. And a plurality of independent logic networks formed by network slicing provide customized services for differentiated services. According to the QoS (quality of service) requirements of different services, the network slice is allocated with corresponding network functions and network resources, and flexible network architecture and arrangement are realized.
As one of enabling technologies of network slicing, the SDN technology helps to implement control/data plane separation of a network, and defines an open interface between the two, implementing flexible definition of network functions in the network slicing. The SDN employs a centralized control plane and a distributed forwarding plane, which are separated from each other, and the control plane performs centralized control on network devices on the forwarding plane by using a control-forwarding communication interface and provides flexible programmability.
Besides the SDN technology, the network slice realizes software and hardware decoupling by means of the NFV technology, and abstracts physical resources into virtual resources. In a traditional communication network, the problems of poor network expandability, difficult capacity expansion and reduction and high deployment cost of new services are caused by the tight coupling of logic and hardware of network equipment. In order to solve the problems, the NFV utilizes an IT virtualization technology to modify the traditional network, so that the functions of all nodes in the network can be realized through software, and the reconstruction of the functions and the intelligent arrangement of the network are realized; the hardware infrastructure of the network can adopt high-capacity servers, switches and storage equipment which meet the industry standard, and the cost of the equipment is reduced.
The network slicing technology can improve the utilization efficiency of network resources, improve the user experience and ensure the QoS of different service requirements. However, in many scenarios, many IT devices do not have a virtualization capability, such as terminals of the ubiquitous internet of things, but the service needs to divide the network services performed on these devices into different network slices according to needs, so as to perform management of allocation and transmission of network resources.
Therefore, a new technical solution is needed to solve this problem.
