The Session Binding feature has been removed for releases 22 and above.  Any release showing this feature should be left DISABLED.


HASH load balancing replaces the need for session binding with the Ribbon DSC database.  A HASH is performed on the specified AVP to find a resulting number.  The numbers derived by the HASH are distributed amongst the members of the Server Pool in the background.  In order to create a dialogue session using the HASH algorithm, you must select an AVP that will have a constant value during that session. For example, Session-ID is recommended as this AVP will remain the same throughout the session providing the same HASH result, which ensures the session messages are routed to the same Server Pool member.
