Hi I'm working on a patch that might saturate the network bandwidth, but I don't want to send more data than the network can bear. The most right outlet of [tcpclient] reports how many bytes it has sent. So what I'm trying to do is to count the bytes I'm sending to [tcpclient] and subtracting the sent bytes from it, assuming that when the number goes up, the upload bandwidth is saturated. However, when I slowly increase the rate until the point where I expect it to saturate the bandwidth, I get _negative_ numbers (more bytes have been sent to the network than I sent to [tcpclient]??). When this happens, the output of [tcpclient] looks like something like this:
print: sent 2048 print: sent 2048 print: sent 2048 print: sent 2048 print: sent 2048 print: sent 2048 print: sent 2048 print: sent 4096 print: sent 6144 print: sent 8192 print: sent 10240 print: sent 12288 print: sent 14336 print: sent 16384 print: sent 2048 print: sent 2048 print: sent 4096 print: sent 6144 print: sent 8192 Either I am misunderstanding what the 'sent' message means or it does not do what it is supposed to do. What is it? Roman
