1. Take the understanding that the media player will return the stream
it received. For the sake of expediency and avoiding
unnecessary waste (Enhanced efficiency), I suggest the introduction
of a new frame format, the "Null reduced frame" and "Null reduced
This is an IP packet which logically contains N bytes of payload,
that is to be transmitted without its payload, but is to be
"understood" as having contained those N octets of payload data, for
administrative and billing purposes; where N is some number between 1
octet and (2^32 - 1) octets.
The media player can then emit these Null-reduced IP datagrams that
contain no ordinary physically payload --- a flag will be set in the
return packet and the frame when transmitted to indicate, that
although the IP datagram physically contains no actual data, it
MUST be counted on all device interface counters and Netflow reports
as X octets, and treated as having contained N octets for the
purposes of billing and peering negotiations.
2. Excellent. Especially if the video player receives streams over
UDP and doesn't verify the source IP address before sending the
stream back, what could possibly go wrong?.
3. On second thought.... why not send the return stream to another subscriber?
Stream the thing only to buffer the content to a subset of the
users' media players. The users' media players then shape the
return stream in order to distribute the content ----- they could
even SEND more data back to the content provider than they receive, if
this benefits the content provider in peering negotiations.
