Description
Technical Field
The invention relates to the technical field of broadband networks, in particular to a method for customizing broadband network slices.
Background
The broadband network slice is to logically divide an entity OLT into a plurality of virtual OLTs by using a virtualization OLT technology, namely vOLT, and allocate a unique vOLT for each virtual OLT, wherein each virtual OLT bears different types of services, thereby realizing the logical isolation of the services. The logical isolation of the vtolt now has three levels, a forwarding plane, a control plane and a management plane. In a forwarding plane, different vOLT slices have independent forwarding domains and independent OSI two-layer and three-layer protocol instances; in the control surface, different vOLT slices have independent object sets, capability set management and account number and attribute management; in the management plane, different vOLT slices have independent resource allocation, object management and authority control.
At present, new OLT equipment of mainstream equipment manufacturers has a slicing function, generally 1 entity OLT can be divided into at most 8 vOLTs, different ONUs under the same PON can be divided into different vOLTs, and the overall price of the equipment is not obviously increased.
The broadband Network slicing technology based on the vOLT can bear public, government and enterprise broadband access equipment and intelligent community access equipment through the same OLT, Optical cable and pipeline resources are multiplexed through shared ODN (Optical Distribution Network) access resources, different services are isolated through a virtualization OLT technology, further, the construction cost is saved on the premise of guaranteeing information safety, the resource utilization rate is improved, the three-party win-win situation of intelligent community constructors, communication operators and community residents is achieved, meanwhile, the efficient operation and maintenance is achieved through intensive management, infrastructure resources are saved by about 60%, pipelines and two thirds of Optical fibers are saved, and therefore the existing communication operators all select to construct an intelligent community Network based on the vOLT Network slicing technology.
However, currently, communication operators determine the allocation of resources in slices in a manually set mode according to application requirements required by B-side clients (i.e. government and enterprise units), or issue the whole network resources to the B-side clients (government and enterprise units), and the B-side clients (government and enterprise units) cannot be flexibly customized. When a C-end client (a person or an Internet of things terminal) joins the slice network, manual configuration is needed, flexibility and intelligent means are lacked, and network performance is directly influenced. Therefore, how to dynamically divide slice resources is important to flexibly design a custom network of a B-end client (a government and enterprise unit) and a C-end client (an individual or an Internet of things terminal) to optionally join the network.
