Re: [Dime] Resolution on action to discuss the need for Realm-Routed-Reports

[Steve Donovan <[e-mail]>]

Consensus is obviously a fleeting and temporary thing.

Let us make sure that we are precise in our definitions of the report
types we are discussing.

Host report - Applies when the destination-host AVP is present in the
request.
Realm-Routed-Request (RRR) - Applies when there is no destination-host
AVP in the request.
Realm - Applies to 100% of requests sent to the realm.

These are the definitions used in our discussions in London and in
various places in our email discussions. 

Can we please agree to use these definitions going forward so we are all
talking about the same thing.

Regards,

Steve
