The　large-scale　distributed　network　has　exposed　increasing　attack　surfaces　to　cyber　attackers.　In　this　paper,　we　present　a　refined　network　measurement　mechanism,　called　DDoS　Collaborative　Mitigation　Mechanism　(DDoSCCM).　Based　on　former　achievements　in　the　programmable　network,　our　work　aims　at　capturing　the　characters　of　abnormal　traffic　and　presenting　an　antedating　reaction,　constrained　by　limited　resources　of　the　switching　ASIC.　In-band　Network　Telemetry　(INT)　technique　achieves　real-time　monitoring　of　the　network　by　utilizing　the　device　data　acquisition　on　the　data　plane.　Our　work　helps　the　network　operator　not　only　to　learn　the　status　of　the　network　but　also　to　issue　an　appropriate　mitigation　strategy　faster　and　more　accurately.　DDoSCCM　aims　at　delegating　both　detection　and　mitigation　processes　to　the　programmable　switch.　Consequently,　the　theoretical　analysis　and　experimental　results　show　that　DDoSCCM　can　meet　practical　requirements　and　have　a　certain　application　value.　©　2021　IEEE.
