+Send Network Packets And Get Packet Loss
+    [Documentation]  Send TCP, UDP or ICMP packets to any network device.
+    [Arguments]  ${host}  ${num}=${count}  ${packet_type}=${ICMP_PACKETS}
+    ...          ${port}=80  ${icmp_type}=${ICMP_ECHO_REQUEST}
+
+    # Description of argument(s):
+    # host         The host name or IP address of the target system.
+    # packet_type  The type of packets to be sent ("tcp, "udp", "icmp").
+    # port         Network port.
+    # icmp_type    Type of ICMP packets (e.g. 8, 13, 17, etc.).
+    # num          Number of packets to be sent.
+
+    # This keyword expects host, port, type and number of packets to be sent
+    # and rate at which packets to be sent, should be given in command line.
+    # By default it sends 4 ICMP echo request  packets at 1 packets/second.
