Abstract：

Mobile　internet　traffic　is　increasing　explosively,　while　many　type　of　applications　are　delay-elastic　in　nature.　We　investigate　the　asynchronous　delivery　oriented　algorithms　to　decrease　peak-to-average　ratio　(PAR),　i.e.,　the　ratio　of　optical　resource　usage　in　the　peak　period　to　the　average　per-period　usage　of　the　fronthaul,　while　improve　the　optical　resource　allocation　efficiency.　In　this　paper,　we　formulate　an　integer　non-linear　programming　(INLP)　optimization　model　and　propose　an　adaptive　generic　algorithm　(GA)　to　realize　the　optimization　in　a　limited　time.　The　simulation　results　show　that　the　maximum　PAR　decreases　by　32%　with　asynchronous　delivery　oriented　optical　resource　optimization.　Besides,　optical　resource　saving　can　be　achieved　with　minimal　influence　on　topology,　and　the　load　difference　can　be　further　reduced.　©　2016　IEEE.
