The values on the GTP' Node tab report the transport layer measurements for the Ga interface in the CGF Nodal, CGF Node, GGSN Nodal, and UMTS test cases.
In the default view, the Reports tab displays the Summary view, which summarizes the measurements for the test session. If your test includes multiple test cases, you can view the report for a single test case by changing the report view...
Unless otherwise noted, cumulative values report the number of occurrences or rates calculated since the start of the test, and per-interval values report the number of occurrences or rates calculated during the interval. You can view either by changing the measurement values...
Elapsed Time is the first measurement on every tab. It reports the amount of time between the start of the test and the end of the report interval.
Test Iteration reports the current iteration in a repeating test session. It is only displayed when a Number of Iterations is defined for the test session.
The following measurements report the number and type of errors encountered at the transport layer.
Socket Ack Timeouts — The number of timeouts that occurred at the TCP socket while waiting for an ACK to a previously sent message.
Socket Lost Packets — The number of times TCP packet loss was detected by the receiving end.
Socket Duplicate Packets — The number of duplicate TCP packets detected by the receiving end. A duplicate packet is detected when a smaller than expected sequence number is received.
Socket Reordered Packets — The number of queued TCP packets that were successfully processed in the correct order after missing required packets were received. These packets are also recorded by Socket Lost Packets since it was not known whether they would be able to be processed at the time they were received.
Total Invalid Packets — The number of packets that could not be processed.
The following measurements record the total packets and bytes sent and received by a node.
Socket Payload Bytes Sent — The number of GTP' payload bytes sent.
Socket Payload Bytes Received — The number of GTP' payload bytes received.
Socket TCP Bytes Sent — The number of TCP bytes sent.
Socket TCP Bytes Received — The number of TCP bytes received.
Total Packets Sent — The number of packets sent.
Total Packets Received — The number of packets received.
Total Packets — The number of packets processed by the node.
Total Packets/Second — The average packets/second throughput for the node.
Total Bytes Sent — The number of bytes sent.
Total Bytes Received — The number of bytes received.
Total Bytes — The number of bytes processed by the node.
Total Bits/Second — The average bits/second throughput for the node.
The following measurements record the number of packets discarded when Packet Discard error injection is used.
Total Received Packets Discarded — The number of incoming packets discarded.
Total Sent Packets Discarded — The number of outgoing packets discarded.
Total Discarded Packets — The total number of packets discarded.
