LocalLB::ProfileFastL4::set_late_binding_state

Introduced : BIG-IP_v11.6.0
Enables or disables late binding for a set of FastL4 profiles. It is disabled by default. Late binding allows flows to start in L7 performing pool member selection based on tags and FIX messages and then transition to FastL4 in the ePVA to manage all subsequent trading traffic. You need a FIX profile in the Performace FastL4 Virtual Server configuration. Layer 7 to Layer 4 flow migration permits, with constraints, hudfilters and iRules to analyze Layer 7 data, select a back-end server, and then push the client and server-side flows down to the ePVA for low latency processing at Layer 4. The client side connection is fully established, and application data is processed, before a server-side connection is established. An iRule uses the application data to select the back-end server to provide a late binding between the client connection and a server connection. This provides application layer intelligence during server load balancing followed by extremely low latency, hardware assisted, packet fowarding via the ePVA.
