Re: [Dime] [dime] #54: OC-Report-Type as mandatory AVP

["Shishufeng (Susan)" <[e-mail]>]

Hello Lionel,

That's because we have no chance to change the situation with Session-id, which is already there for many years. This does not mean it is correct. :)

As I clarified many times, OLR-Report-Type is not useful for some Diameter applications or deployment, this could justify its optionality.

If everyone can live with the texts as they are, maybe we can close the discussion on it and move on.

Best Regards,
Susan

IMHO it is a lot of fuse for something not so critical!
Session-id is for no use at all in a lot of Diameter applications and no one complains :)

Here it is even simpler: there is a clear use of this AVP. This info (the explicit AVP or the default value) needs to be taken into account in the process of the received OLR and any compliant implementation needs to be able to understand the OLR-Report-Type.
So except "optimization", what is the rational not to make it required in the OLR?

Hi all

I am also in line with the agreement tendency as that OC-Report-Type is not required (so to keep the text as it is in the draft); I expressed this  preference a while ago.


Best regards

JJacques

Susan,

We are in the middle of the discussion and have not yet reached consensus.

I agree with Jouni on making it explicit.  Either way, we should try to make a decision quickly.

Lets have it explicit then. Use '<' and '>' to make the position fixed.

I'm ok with either direction but generally lean toward being explicit.



Do we have other opinions?

Hello,

I think the agreement tendency is the contrary: OC-Report-Type is not required, while default value is Host. i.e. it will remain as it is now in the draft.

This may be of some advantage for some applications that may only use Host, as long as they may never generate Realm reports.

If there is consensus on this, I will go with this.

All,



Do we have consensus that the OC-Report-Type AVP is required?



If so then one change would be as indicated in the syntax definition proposed by Lionel.  We would also remove wording on the default value.



Jouni,



How do we indicate a fixed position for an AVP?



I presonally don't see this as critical but we can add this requirement if there is consensus.

Steve

Hi,



How having the AVP could be less error prone if it has a default

value and the receiver knows exactly how to proceed when the AVP is

not present?



If a node does not include it when it should, the implementation is

broken. Wouldn't a broken node be able to put wrong report type into

the AVP even if the AVP is mandatory?



Anyway, if it is my statement keeping issue #54 still open, consider

it resolved from my side. I am OK making the OC-Report-Type AVP as

required/mandatory AVP. Should we also consider it having a fixed

position just after the OC-Sequence-Number AVP as well since it is

going to in every OC-OLR?

Hello all,



I understand JJ point of view, but I still tend to prefer to make it mandatory, since I think this is less error-prone, since the only node that knows the requested Report-Type is the reporting, if for any reason a reporting is omitting it (since it is optional), it will be always interpreted as HOST, but this type may be wrong.



I think DEFAULT values should never be error-prone, but used in "general cases", as a simplification, like e.g. a default for the Validity-Duration. Default Validity-Duration will never be an "error", it could be not the best value (compared with another value perfectly tuned to reporting node overload situation) but never the use of a Default value should lead to an erroneous behavior.

I actually prefer making it mandatory. The cost of adding it is trivial--even more so for a reporting node that only supports the default. The value of having it is less opportunity for interop errors.

Agree that it is a small optimization, which I put there because at

the beginning there seemed to be a lot of worry on every extra AVP

;-)



I prefer having the AVP optional but with a default value just like

it is now. We have the same for the reduction percentage and the

validity time as well.

Hi Mcruz



The current description indicates that when not present the OLR is of type Host, which was fine for me and keeps my preference.

We may have  deployments where Realm OLR is not used, or where statistically the HOST type is the most frequent, so to have the grouped OLR-AVP containing a minimum of AVPs minimizes parsing. I agree it is a small optimization.

Hi Maria Cruz,



I'm assuming that you mean "required" instead of "mandatory", right?



So instead of:



OC-OLR ::= < AVP Header: TBD2 >

           < OC-Sequence-Number >

           [ OC-Report-Type ]

           [ OC-Reduction-Percentage ]

           [ OC-Validity-Duration ]

         * [ AVP ]



You would prefer:



OC-OLR ::= < AVP Header: TBD2 >

           < OC-Sequence-Number >

           { OC-Report-Type }

           [ OC-Reduction-Percentage ]

           [ OC-Validity-Duration ]

         * [ AVP ]



And I'm fine with this proposal.



Cheers,



Lionel

#54: OC-Report-Type as mandatory AVP



Now in chapter 4.6:



 The default value of the OC-Report-Type AVP is 0 (i.e. the host

report).



This AVP is always required, right? Then, I think it is more precise that  we define this AVP as mandatory.
