With　the　further　deepening　and　upgrading　of　digitization　and　informatization　of　industrial　enterprises,　the　industrial　network　needs　higher　flexibility　and　reliability.　As　a　comprehensive,　unified,　and　standard　new　industrial　Ethernet　technology,　Time-sensitive　network　technology　makes　industrial　network　technology　and　industrial　ecology　more　open　and　dynamic.　Time-sensitive　Software-defined　network　introduces　the　concept　of　software-defined　network　based　on　time-sensitive　network,　which　makes　the　whole　network　more　real-time　and　flexible.　With　the　emergence　of　dynamic　applications,　time-sensitive　networks　also　need　to　be　updated　in　real-time.　The　old　update　mechanism　cannot　ensure　that　the　new　and　old　flow　is　separate　from　one　another,　resulting　in　network　congestion.　In　this　paper,　a　new　scheduling　update　scheme　is　proposed,　which　eliminates　the　conflict　between　the　old　and　new　traffic　by　separating　the　old　scheduling　scheme　from　the　new.　The　experimental　results　on　two　different　network　topologies　show　that　the　update　time　of　the　proposed　scheduling　scheme　is　shortened　by　5.68%　compared　with　the　traditional　scheduling　scheme.　The　network　resource　utilization　of　the　two　network　topologies　decreased　by　3.3%　and　10.02%,　respectively.　©　2023　SPIE.
