Abstract
Methods and apparatus to debug a network application are described. A described example network includes a live control network to collect control messages to create a history of network states, the history of network states reflecting an order in which control messages are processed, the live control network to roll back from a current state to a past state upon detection of an improper sequence of messages and to process the messages in a corrected sequence, the corrected sequence to be stored in the history. The described example network further includes a virtualized network corresponding to the live control network, the virtualized network responsive to a command from an operator to step through the history to facilitate debugging.
