+#!/bin/bash
+#
+# This script is run by the policy closed loop to generate traffic (DNS packets) to the DNS
+#
+# Usage: dnstraffic.sh <DNSIP> <RATE_PER_SEC> <ITERATIONS>
+#
+# The DNSIP is that of the DNS vLoadBalancer.
+# The RATE_PER_SEC is the approximate number of nslookup requests generated per second.
+# The ITERATIONS is roughly the number of seconds to run the test. Note that the Robot
+# will kill this script after the validation is complete.
+#
+# The validation portion of the script has done a successful lookup, so the point of
+# these requests is to generate DNS packets. We do not care about the results. The timeout
+# of 1 second is to ensure we do not flood the process table with long waits
+# on failed lookups.
+#
+# We generate an approximate rate because we sleep for a full second so the RATE_PER_SEC
+# should have some slop in it. We only need to drive this to 20+ per second, so a 35
+# per second should fall within the range to trigger the polciy check and prvide enough
+# to validate even distribution without spawning a 3rd DNS
+#
