F5 outside flow Bandwidth control

I may be misunderstanding the question a bit, but LC/GTM combo can assist with inboud or oubound traffic. Did you check out the manual? I haven't done much LC in a few years now because I just don't get the calls anymore but please review the manual and let me know if I misunderstood. As you know, with any product, you have what is really called Traffic Shaping when it comes to traffic leaving for the internet. (Let me not get sidetracked here.) Having said that, if you have LTM only, I think this it is possible but it will probably take some work. The real problem is going to be, "How to monitor/check the bandwidth?" I don't believe there is a built in tool/command for that. You may have to have your mgmt station or some device poll via snmp the stats for the interface to know when bandwidth is an issue. From there you could use iControl or a script to log on to the box and issue the appropriate tmsh commands.
