テスト環境 
テスト環境は前回STTを測定した2台の物理機を依然として使っています.既存のネットワーク環境は以下の通りです.
node 1、duduo.seg、 
  • eth 0:10.23.56.14、  1000 M/s、 bb-ex
  • eth 6:10.23.56.15、 100000 Mb/s,out-off-band management
  • eth 7:192.168.122.2,000 Mb/s,bb-phy

    node 2,voltorb.seg
  • eth 0:10.23.56.21、  1000 M/s,out-off-band management
  • eth 4:192.168.122.3,10000 Mb/s,bb-phy
