The Retransmissions Report presents retransmission statistics for global setup commands
when blocked packets are retransmitted. The retransmission timer accounts for the age of
the packet before it is blocked. It schedules a packet retransmission only after the packet
is actually blocked somewhere in the network. The retransmission time is adjusted so that
the packet is retransmitted the specified delay after the packet was originally transmitted.
It reports on quantities such as the number of times a packet has to be retransmitted, and
the number of packets that are retransmitted when a blocked packet occurs.
