error solution

  • 出現TabError: inconsistent use of tabs and spaces in indentation依下列解決方案
  • 查看是哪個文件發生錯誤 image
  • 到引發錯誤的檔案解決
vim network_monitor.py //若是network_awareness.py錯誤則vim network_awareness.py。以下步驟一樣
:set expandtab //直接打冒號進入指令模式，再輸入冒號後的指令
:%ret! 4

Quick start

choose ct, ut, md scenario

  • fattree.py image

start mininet

cd ~/Traffic-aware-separating-flow-scheduling-framework-in-SDN-based-data-center-network
sudo python fattree.py

  • 啟動mininet後須馬上啟動controller，中間時間不可超過60秒。

start controller

ryu-manager --observe-links main.py

Collect experimental results

  • 執行完成後在mice_flow資料夾中會有mice flow的report檔案，server_report中有elephant flow的report檔案
  • 分別執行collectPut.py與wget-collect-FCT.py收集elephant flow的goodput和mice flow的FCT
  • 執行完後在同目錄中會產生Put.ods與FCT.ods分別記錄elephant flow的goodput與mice flow的FCT
python collectPut.py
python wget-collect-FCT.py
