DES Structure Clause Samples

DES Structure. The NSIF File Header accommodates up to 999 DES. Each DES shall consist of a DES Subheader and a DES User-Defined Data (DESDATA) Field (similar to the way a Standard Data Segment has a Subheader and an adjacent associated Data Field). The DES Group in the NSIF File Header contains the number of DES in the NSIF File, the length (size) of each DES Subheader, and the length (size) of the DESDATA field. The field size specifications in the NSIF File Header allow each DES to be just less than one gigabyte in length. The DES Subheader shall contain the fields defined in Table C-1-8. The DES structure includes a mechanism for defining additional DES Subheader fields (DES User-Defined Subheader Length (DESSHL) Field and DES User-Defined Subheader Fields (DESSHF) Field), and for defining encapsulated data (DESDATA). This structure encourages the formation of a specific DES in a manner similar to the way Standard Data Segments group fields (Subheader fields) that describe the data and follow it with the data.
