5G network slicing

5G network slicing is a <a href="/facts/Network_architecture/b9IWEJIU">network architecture</a> that enables the <a href="/facts/Multiplexing/YE7hK8cw">multiplexing</a> of <a href="/facts/Virtualization_of_Network_Functions/74bwhhoJ">virtualized</a> and independent logical networks on the same physical network infrastructure. Each network slice is an isolated <a href="/facts/End-to-end_principle/6RkKmdUm">end-to-end</a> network tailored to fulfill diverse requirements requested by a particular application.
For this reason, this technology assumes a central role to support <a href="/facts/5G/yVb460m4">5G</a> mobile networks that are designed to efficiently embrace a plethora of services with very different service level requirements (SLR). The realization of this service-oriented view of the network leverages on the concepts of <a href="/facts/Software-defined_networking/MJGFxyoj">software-defined networking</a> (SDN) and <a href="/facts/Network_function_virtualization/74bwhhoJ">network function virtualization</a> (NFV) that allow the implementation of flexible and scalable network slices on top of a common network infrastructure.
From a <a href="/facts/Business_model/TL9XXsQa">business model</a> perspective, each network slice is administrated by a <a href="/facts/Mobile_virtual_network_operator/ap1fuDkN">mobile virtual network operator</a> (MVNO). The infrastructure provider (the owner of the telecommunication infrastructure) leases its physical resources to the MVNOs that share the underlying physical network. According to the availability of the assigned resources, a <a href="/facts/Mobile_virtual_network_operator/ap1fuDkN">MVNO</a> can autonomously deploy multiple network slices that are customized to the various applications provided to its own users.
