From a provider ’ s perspective , network slicing involves offering different customers their own slice , then allowing each customer to manage their own network slice independently . Critically , each network slice is , logically , entirely separate from any other . But , all of these individual allocated slices all sit within one , single physical infrastructure .
“ Network slicing is a form of virtual network architecture using the same principles behind software defined networking ( SDN ) and network functions virtualisation ( NFV ) in fixed networks ,” explained Vishy Ramu , the VP of 5G & Digital Solutions at Tata Communications .
“ It allows multiple virtual networks to be created on top of a common shared physical infrastructure , which can then be customised to meet the specific needs of applications or services .”
As a result , it enables network providers to more effectively fulfil numerous different market verticals , while also increasing their revenue .
“ To date , telecommunications networks have been predominantly built around mobile broadband . This means that all users have had to leverage the same end-to-end network for their applications regardless of requirements ,” outlined Blessing Makumbe , Ericsson ’ s VP and Head of Digital Services for the UK and Ireland .
“ However , with network slicing functionality , operators can create thousands of virtual , independent networks within the same physical network and purposely build each network to the mobile-magazine . com 73
