Chapter 2. Symmetric Messages and Asynchronous Messages (Part 1)

This chapter describes the steps involved in sending and processing symmetric messages and asynchronous messages in the switch and contains the following recipes:

  • Sending and processing a hello message
  • Sending and processing an echo request and a reply message
  • Sending and processing an error message
  • Sending and processing an experimenter message
  • Handling a Set Asynchronous Configuration message from the controller, which shows a list of asynchronous events of interest to the controller
  • Handling a Get Asynchronous Configuration message from the controller, which is used to fetch a list of asynchronous events that will be sent from the switch
  • Sending a Packet-In message to the controller
  • Sending a Flow-removed message to the controller
  • Sending a port-status message to the controller
  • Sending a controller-role status message to the controller
  • Sending a table-status message to the controller
  • Sending a request-forward message to the...
