All those AVPs that are/can be decoded by an intermediate Diameter Agent should not be encrypted. For example: Destination-Host, Destination-Realm, Proxy-Info, Route-Info and so on.
Can someone please explain difference between these two. Could both Result-Code and Experimental-Result AVPs be used in same diameter or only one of them is allowed ?
In a Diameter session, what all states client has and the server ? And how does the state transition work between client and server by exchanging different types of messages ?
