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　up-to-date　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.
