Measurement times

In this configuration there are tests in two directions between each site pair. This implies that in contradiction to subsection 3.2.2 the situation per site is symmetric here. When there are n sites, for each site there are (n - 1) roundtrip / throughput measurements and off course one machine load measurement, so for all sites there are n (n - 1) roundtrip / throughput measurements and n machine load calculations to be done.

In this setup there are nine sites participating. No tests are performed at the connections RUS - ZAM and RUS - ZELAS, so for all sites there are maximal 28 roundtrip / throughput measurements and 7 machine load calculations to be executed. Also per site there are (maximal) 6 roundtrip / throughput measurements to be done. All roundtrip measurements are performed simultaneously. This implies that each site is (maximal) 100 seconds busy with the measurements. The tests are repeated each hour, therefore, the average load for each site is 2.8 %.
