Abstract：

In　data　center　networks　based　on　SDN,　mice-flows　are　latency-sensitive　and　packet　loss　sensitive.　Meanwhile,　they　account　for　the　majority　of　traffic　in　the　network,　most　flow　rules　are　installed　to　direct　the　forwarding　of　mice-flows.　According　to　the　characteristics　mentioned　above,　this　paper　proposes　a　joint　balancing　flow　table　and　reducing　delay　(BFTRTD)　scheme　for　mice-flows　in　data　center　networks　to　efficiently　utilize　limited　flow　tables　and　minimize　the　delay　for　mice-flows.　In　this　scheme,　a　novel　evaluation　index　for　table　balance　is　proposed　to　balance　flow　tables,　combining　with　the　delay　of　the　path　to　initialize　routes.　In　addition,　this　paper　also　adopts　the　uptodate　flow　rules　installation　mechanism　to　further　guarantee　the　transmission　quality　and　delay　of　mice-flows.　We　evaluated　the　proposed　BFTRTD　in　terms　of　average　packet　loss　rate　and　average　delay　of　mice-flows.　Simulation　results　show　that,　compared　with　ECMP　and　DIFF-　Mice,　the　proposed　BFTRTD　scheme　reduces　the　average　packet　loss　rate　by　an　average　of　4.5%　and　5.9%,　while　decreases　the　average　delay　by　an　average　of　4.1%　and　4.7%,　when　the　flow　arrival　rate　is　between　120　Mbit/min　and　280　Mbit/min　where　network　load　goes　from　low　to　high.　©　2019　IEEE.
