I programed to send compressed video data from a network camera to a PC.
The network camera system sends in real-time a 11KByte video frame and ten 500Byte video frames a second
So it sends data less than 200 Kbps in transport layer level (UDP protocol).
But on Ethernet it consumes almost ten times bigger bandwidths.
I can not hook more than two network cameras on 10 base Ethernet and more than 10 network cameras on 100 base T Ethernet.
If I am not wrong, Ethernet has too much overheads to transfer data.
Did I miss something or have mis-configurations?
Any idea to optimize them?

bkna.

If you are sending steady streams of video, look at your packet sizes, they ought
to be right around the max size. Also look at the error rates and what kind of
errors. I will speculate that you have a screwy cable messing with the signal, or
a bad card someplace that is producing a lot of collisions.
