Aiming　at　the　problem　that　in　the　mobile　Internet　platform,　the　traffic　load　(that　is,　the　time　the　task　participant　costs　when　arriving　at　the　task　execution　site)　has　a　great　impact　on　load　balancing　of　task　participant　and　execution　efficiency　of　task　in　the　workflow　system,　this　paper　proposes　a　load　balancing　task　assignment　strategy　considering　the　traffic　load.　On　the　basics　of　considering　execution　load　of　task,　the　strategy　fully　considers　the　traffic　load　due　to　the　decentralization　of　the　task　execution　site　when　calculating　the　load　of　task　participant.　Additionally　to　the　variance　of　the　load　sequence　constituted　by　loads　of　all　the　task　participants　as　a　standard,　selecting　the　assignment　scheme　with　the　smallest　variance　of　load　sequence　after　task　assignment　in　all　assignment　schemes.　The　application　of　this　strategy　can　significantly　improve　the　load　balancing　effect　of　task　participant　and　the　overall　execution　efficiency　of　the　task　in　the　workflow　system　under　the　mobile　Internet　platform.
