A few ideas concerning real-time video over TCP (in July 1997; things
may change in the future).
- TCP_NODELAY should be activated (Nagle's algorithm
disabled in other words). However, we've to be aware that this
may hurt the network...
- The picture should be taken just before sending it (NOT using a
buffer ring, as possible for example with the SGI's). The reason
is that, given the transmission time, using a buffer ring may
give you a very late image.
