Erez,

 

I agree there should be a bit identifying the grouped AVPs.

To whom it may concern:

======================

 

Dealing with the Diameter standard for more than 2 years, I always had the following question, I never dared to ask. But even after 2 years, I do not seem to have a good answer for it:

 

In RFC 3588, section 4.2 – AVP Data Formats, “Grouped” is defined as a “basic type”. Doesn’t it make more sense to set a flag for Grouped AVP in flags section? Group may be basic but it is not a real type. It’s just an indication of a complex data structure.

 

If “Grouped” is defined as a flag, it will simplify any parser’s work – and performance is such a rare resource.

 

Thanks in advance,

Erez Nassimi
