Install mininet

mininet script:

• 1 switch, 2 host
• set fail mode to switch: secure/standalone

pingall under secure and standalone fail mode

understand different between secure and standalone fail mode

• controller set two flow entries to each switch
  • packet come in from port A packet out to port B
  • packet come in from port B packet out to port A

Mininet:

• Modify Mininet script from HW2, switches connect as a link,hosts connect to head and tail switch, user can assign the number of switches when execute script
• This new mininet script should work well with HW2 ryuapp

Ryu:

• controller set a flow entry to each switch
  • when receive packet type is LLDP, send to controller
• controller let switches send LLDP packet out to all normal active port after switch connect to controller
• controller need packet in handler to handle lldp packet from switch
• design a data structure to store lldp result
