[IPFIX] octetArray/hextetArray/32tetArray RE: Re: WG LC: IPFIX documents

[[e-mail]]

Hi Paul,

(restricted the distribution lists to OPSAWG and IPFIX)

The octetArray type is especially confusing as these are really hextetArrays.


[Med] Not sure we need a new data type here as octeArray is defined as follows:
   The octetArray data type has no encoding rules; it represents a raw
   array of zero or more octets, with the interpretation of the octets
   defined in the Information Element definition.

The draft proposes the encoding not of octets, but of 16-bit values. Therefore it's not an "array of zero or more octets" but rather, an "array of zero or more hextets".

[Med] I was assuming that <interpretation of the octets defined in the Information Element definition" in the excerpt is not restrictive and leave it to the definition of the IE to determine how to interpret the octets (including when grouping them into 16 bits, 32 bits, etc.). Given that interpreting the data requires anyway digesting the structure in the definition not only the abstract data type, I thought that we don't need to define new types for specific octet- blocks, but I may be mistaken.
