Network Slicing In 5g: Possible Military Exclusive Slice

5G communication networks are under promulgation globally and in India the same will be deployed by second quarter of 2022. 5G networks provide much needed flexibility non monolithic architecture for implementation of various services through core network. 5G follows independent and autonomous architecture in core network and thus provide means for creation of multiple logical networks on the same physical infrastructure called as Network Slicing. Multiple slices of the same network are available by means of virtualization and network orchestration by means of network slicing which segments the traffic flow as per user customization. This can also be used for creation of private exclusive network with customized services and features. Militaries across the globe have been using their self-deployed hardware and software which are exclusive and isolated from public networks for deployment of isolated military networks akin to commercial telecommunication networks. Though military networks emerge out of technologies used in public switched networks but since they require secrecy and isolation thus remain aloof from public networks and over a period also get outdated, since a large infrastructure has to be created for deployment of networks which also requires huge capital thus these networks are not upgraded periodically as in case of civil networks. Network slicing function of 5G provides means of using the public telecom networks with exclusivity and secrecy without deployment of infrastructure and still maintain the required isolation. An exclusive military network slice on telecommunication service providers (TSPs) infrastructure will enable economy of use, low cost of ownership and customized services with increased network security or propriety security algorithms as per requirement of Army.
