RFC 5841            TCP Option to Denote Packet Mood        1 April 2010

1.  Introduction

   In an attempt to anthropomorphize the bit streams on countless
   physical layer networks throughout the world, we propose a TCP option
   to express packet mood [DSM-IV].

   Packets cannot feel.  They are created for the purpose of moving data
   from one system to another.  However, it is clear that in specific
   situations some measure of emotion can be inferred or added.  For
   instance, a packet that is retransmitted to resend data for a packet
   for which no ACK was received could be described as an 'angry'
   packet, or a 'frustrated' packet (if it is not the first
   retransmission for instance).  So how can these kinds of feelings be
   conveyed in the packets themselves.  This can be addressed by adding
   TCP Options [RFC793] to the TCP header, using ASCII characters that
   encode commonly used "emoticons" to convey packet mood.

1.1.  Terminology

   The keywords MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD,
   SHOULD NOT, RECOMMENDED, MAY, and OPTIONAL, when they appear in this
   document, are to be interpreted as described in [RFC2119].

2.  Syntax

   A TCP Option has a 1-byte kind field, followed by a 1-byte length
   field [RFC793].  It is proposed that option 25 (released 2000-12-18)
   be used to define packet mood.  This option would have a length value
   of 4 or 5 bytes.  All the simple emotions described as expressible
   via this mechanism can be displayed with two or three 7-bit, ASCII-
   encoded characters.  Multiple mood options may appear in a TCP
   header, so as to express more complex moods than those defined here
   (for instance if a packet were happy and surprised).

              TCP Header Format

         Kind     Length     Meaning
         ----     --------   -------
          25      Variable   Packet Mood

3.  Simple Emotional Representation

   It is proposed that common emoticons be used to denote packet mood.
   Packets do not "feel" per se.  The emotions they could be tagged with
   are a reflection of the user mood expressed through packets.

   So the humanity expressed in a packet would be entirely sourced from
   humans.

   To this end, it is proposed that simple emotions be used convey mood
   as follows.

      ASCII                Mood
      =====                ====
      :)                   Happy
      :(                   Sad
