According　to　the　high　operating　costs　and　a　large　number　of　energy　waste　in　the　current　data　center　network　architectures,　we　propose　a　kind　of　trusted　flow　preemption　scheduling　combining　the　energy-saving　routing　mechanism　based　on　typical　data　center　network　architecture.　The　mechanism　can　make　the　network　flow　in　its　exclusive　network　link　bandwidth　and　transmission　path,　which　can　improve　the　link　utilization　and　the　use　of　the　network　energy　efficiency.　Meanwhile,　we　apply　trusted　computing　to　guarantee　the　high　security,　high　performance　and　high　fault-tolerant　routing　forwarding　service,　which　helps　improving　the　average　completion　time　of　network　flow.
