iRule detect any IP that comes in at x rate a minute

Lets say we have an external IP coming in and is completely over taxing a VS. Is there a way within an iRule(or profile) to throttle the connection? In this case

 

external ---------------------------> VS

 

166.166.166.166 -------------->270.270.270.270

 

Using up to 300 MB of bandwidth. Want to throttle to 50mb. Thank you for anyone who can help.

    Alternatively you could create a Rate Class and apply it in the iRule, based on the source IP. Is the high bandwidth inbound or outbound?

    OK, so I knocked this up; 

    
when CLIENT_ACCEPTED {
 if { [IP::addr [IP::client_addr] equals x.x.x.x] } {
  rateclass name_of_your_rateclass
  log local0. "Bandwidth Hog: [IP::client_addr] detected, Rate Class applied."
 }
}

    And found this right afterwards (which has an example which is essentially the same): https://devcentral.f5.com/wiki/iRules.rateclass.ashx

    No idea what happens if the client opens multiple connections. Perhaps you can let us know?
