+ # This program executes an ODL performance test. The task is executed in
+ # four steps:
+ #
+ # 1. The specified number of flows is added in the 'add cycle' (uses
+ # flow_config_blaster to blast flows)
+ # 2. The network is polled for flow statistics from the network (using the
+ # inventory_crawler.py script) to make sure that all flows have been
+ # properly programmed into the network and the ODL statistics collector
+ # can properly read them as long as specified
+ # 3. The flows are deleted in the flow cycle. Deletion happens either in
+ # 'bulk' (using the config_cleanup) script or one by one (using the
+ # flow_config_blaster 'delete' method)
+ # 4. Same as 2. Monitoring and reporting the state of the inventory data
+ # for a specified period of time.
