  Network slicing allows mobile network operators to open their physical
network infrastructure platform to the concurrent deployment of multiple
logical self-contained networks, i.e., network slices. In this paper we propose
and analyze ONETS: an Online NETwork Slicing solution that (i) builds on the
budgeted lock-up multi-armed bandit mathematical model and properties, (ii)
derives its analytical bounds in our proposed extension for network slicing,
(iii) seamlessly integrates into the 3GPP architecture, (iv) proves its
feasibility through a proof-of-concept implementation on commercial hardware
considering three network slices and (v) allows for the design of a
low-complexity online network slice brokering solution that maximizes
multiplexing gains.
