Proxy and number of packets [my improved proxy]



Hi Daniel,

Thanks for the hint. Do you have any documentation, papers, tutorials,
etc about Darwin. I'm testing my proxy, but there is still having a packet
loss. To isolate my proxy and Darwin, I put my proxy in the same machine
of the Darwin and there is packet loss. 

Other strange behaviour is when I run my proxy to measure the number of
packets received by it, it is different every time that I run.       

What does the 'reliable udp' mean in the Darwin? You said to look at the
rtcp packets. My proxy implements only RTSP e RTP protocols, it is
necessary to implement RTCP? Do you know which algorithm Darwin uses to
divide the stream in packets? Is it dependable of the bandwidth?   


Thanks in advance
  Marisa
