Hello, I have a task that must be solved.
So it consists of the following. You must write code in a language c / C + + / C #, Pascal, VB, maybe another.
So I have one source and one receiver, as is done in relation to two channels. Protocol is TCP. You must send 20 packages from source to receiver, the algorithm is as follows: 8 package in the first channel, then one package per second channel,and then again in the first 8 channel package, etc. If some can help.
