Thanks Murphy I will try this. Actually I am doing this to drop flows of users when flows from some priority users arrive so that their traffic can pass with no delay. This is really helpful I will try this. On Tue, May 7, 2013 at 8:20 AM, Murphy McCauley wrote: > Certainly you can delete flows b

Certainly you can delete flows by sending an ofp_flow_mod. Selecting which ones you want to delete is the potentially tricky part and will depend on which ones you want to delete and why. Potentially you can just pay attention to how many you've installed and how many have expired (by setting
