SDN

HW1

  • 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

HW2

  • Install Ryu
  • Write a ryu app:
    • 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
  • Modify HW1 mininet script ,connect to remote controller

HW3

  • 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

HW4

  • learn how to write and use Ryu RESTful API
  • use RESTful API to GET HW3 LLDP topo

RYU_ODL_LLDP

  • Test for multi controller and try to get topo between different controller
  • base on HW3 mininet topo and HW4 Ryu app
