有空還是要玩玩看, 一個是全專屬架構,有了rest API和controller就說自己是SDN了
另一個是whitebox switch+agent, 也是自己的controller, 看從何角度看

ARP還好, 實體機或虛機接入就有agent來看
OAM才是挑戰
The only way to solve this one is to run some OAM protocol between adjacent switches, and doing that through the controller every 100 msec with packet-out and packet-in messages won’t get you very far in terms of scalability.
