Mininet x OpenFlow x Controller relationship

如果要實作 SDN ,先懂整體的架構,SDN 並非單一單元,缺其中一個單元的了解,就無法完成完整的Project,也就是說我們要懂 Switch,協定: OpenFlow,Controller還有其虛擬環境模擬工具: Mininet，才能更理解sdn 以及跑實驗。

List of SDN controller software
Beacon
Faucet
lighty-core
Cherry
NOX/POX POX 裝Mininet時也就同時裝了POX/研究初階段
ONOS 商業型 / Controller界的當紅炸子雞嗎 / 沒有用過
Open vSwitch
OpenContrail
OpenDaylight (controller baseline project upon which many other controllers are built)
OpenKilda
Project Calico
Project Floodlight
RUNOS
Ryu Controller 研究型 / 入門較容易 / 有用過
The Fast Data Project

• Ryu vs ONOS

• OpenFlow
  • spec: https://www.opennetworking.org/wp-content/uploads/2014/10/openflow-switch-v1.5.1.pdf

  OpenFlow是一種網路協定，運作於網路七層的第二層，也就是資料連結層（Data Link Layer）。

  Mininet is also a great way to develop, share, and experiment with OpenFlow and Software-Defined Networking systems.
