In the fifth-generation communication systems, Network slicing (NS) aims at replacing the traditional “one-size-fits-all” network architecture. Thanks to its ability to provide a higher network flexibility, NS may address diverging requirements imposed by verticals while providing a reduction of operational costs. NS exploits network virtualization to elastically allocate and reallocate infrastructure resources tailored to time-varying needs of various applications. With NS, multiple slices, i.e., customized, isolated, and service-dedicated end-to-end logical networks can be established and operated simultaneously on a common physical infrastructure network.
Network slicing opens many research directions such as the resource provisioning problem to provide slices with guaranteed quality of service, the optimal share of virtualization between the radio heads and the access network, the slice resource alocation accounting for uncertainties related to the user number, demand, locations… MILP are often encoutered in this context, and efficient heuristics have to be found.
