DOCUMENT NUMBER:   CCSDS 133.0-P-1.1          Pink Book, Issue 1.1
DOCUMENT NAME:     Space Packet Protocol
DATE ISSUED:       August 2019
PAGE NUMBER:       3-1, 4-1     PARAGRAPH NUMBER:  3.2.2.1, 3.2.3.1, 4.1.1.2
RID SHORT TITLE:   Minimum packet length
------------------------------------------------------------------
DESCRIPTION OF REQUESTED CHANGE:  (Use From: "..." To "..." format)

From (3.2.2.1):
"It shall consist of at least 7 and at most 65542 octets, but
individual project organizations may establish the maximum length
to be used for their projects, taking into account the maximum SDU
size in all subnetworks traversed by the Space Packet."

To:
"It shall consist of at least 7 and at most 65542 octets, but
individual project organizations may establish the maximum and
minimum length to be used for their projects, taking into account
the maximum SDU size in all subnetworks traversed by the Space
Packet and the minimum required by possible alignment constraints."

Similiar changes for 3.2.3.1 and 4.1.1.2.

------------------------------------------------------------------
CATEGORY OF REQUESTED CHANGE:
     Technical Fact ___    Recommended _X_    Editorial ___
NOTES:
TECHNICAL FACT:  Major technical change of sufficient magnitude as to
 render the Recommendation inaccurate and unacceptable if not
 corrected.  (Supporting analysis/rationale is essential.)
RECOMMENDED:  Change of a nature that would, if incorporated, produce
 a marked improvement in document quality and acceptance.
EDITORIAL:  Typographical or other factual error needing correction.
 (This type of change will be made without feedback to submitter.)
------------------------------------------------------------------
SUPPORTING ANALYSIS:

At several locations (chapters 3.2.2.1, 3.2.3.1, 4.1.1.2) it is
explicitly mentioned that the maximum packet length allowed may be
tailored to be less than the maximum given in the standard. The
opposite however, requiring more octets for the minimal packet
length for a specific mission than the one octet in the standard
is never mentioned. Use case might be interesting e.g. for 64bit
alignment of packets.
