DDSIRTP26 — Wrong data type for serializedPayload in DATAFRAG

  • Key: DDSIRTP26-29
  • Status: open  
  • Source: Atostek Oy ( Juhana Helovuo)
  • Summary:

    Table 8.42 gives the Structure of the DataFrag Submessage. The last field is specified to have type "SerializedPayload". If this would be the case, the contents of that field should be decodable as a SerializedPayload object, as specified in Section 10, but really the field seems to contain just a fragment of a SerializedPayload. A complete series of fragments must be concatenated to get a valid SerializedPayload. Therefore, the type should be changed to indicate that it is a fragment, not a whole object.

    A similar problem exists in Section DataFrag Submessage.

    More generally, there seems to be confusion in terminology between SerializedPayload / SerializedData / SerializedDataFragment.

    The latter two seem to be suitable for use in the payload field of Data and DataFrag submessages, respectively, and they are defined in -.18, but SerializedPayload is not defined in 8.3.5 at all.

    Section 9.4.2 (PSM) again does not define a mapping for SerializedData / SerializedDataFragment, but for SerializedPayload instead.

    Please clarify the relationship between the aforementioned terms.
