Reason for traffic disappearence between server&client

[jitechno]

If I understand you correctly, you have an algorithm that regulates the rate of transmission, and the algorithm sometimes causes the traffic to drop to zero.

If so, then post your algorithm. You state that the traffic goes to zero at "random moments", but the graph you show does not look very random, and actually seems somewhat periodic, such that the algorithm might not be working as expected.

No, Mike, in common, I dont requlate rate of transmission. I could do it for test, but I dont see sense for it. I set fixed rate (f.e. N packets per sec), I can change it to other value. there is nothing algorithmic. Whole algorithm is a sending of N packets , more correctly, one array of N packets, nothnig more.

Graph is not periodic, normal graph likes constant level with deviations. I put only fragment to show radical degradation of service.
