I doing a client and server program streaming video. There is another computer that will be broadcasting packets into the network. This 3 computers are connected by a 10Mbit hub. I have to send a video over to the client at a fixed time of 4.08 secs. This is the correct time. But when i pump my traffic to 30% with the broadcaster. The video will occupy 60% of the traffic. When i send over this video, there is a lot of collisions. My time was increased to 5.3secs which is not acceptable. Anyway have any solutions for the problem? I have to maintain 4.08 sec with and without heavy traffic

Get a 10/100 switch, and make sure all your ethernet cards are communicating in full-duplex mode.

Yeah no kidding, you need a switch. Streaming video over 10Mbit shared medium is NOT going to work, especially when it's broadcast rather than unicast!

In this case a 10/100 hub would possibly be a little bit faster on this small scale for just 2 or 3 computers than a switch would. We've proven that a 10/100MBit hub is faster running at half duplex than a 10/100MBit switch at full duplex. it all depends on the amount of computers/traffic.
