The values on the GTP' tab report the Ga processing measurements for the GTP' protocol layer 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 record the number and types of messages exchanged between the CGF node and the GSNs or the SGSN CGF node and the CGF.
| NOTE: Data Record Request indicates the request from CGF clients, in SGW Nodal and Node, PGW Nodal and Node test cases. |
Node Alive Requests Received — The number of Node Alive Request messages received.
Node Alive Requests Sent — The number of Node Alive Request messages sent.
Node Alive Responses Received — The number of Node Alive Response messages received.
Node Alive Responses Sent — The number of Node Alive Response messages sent.
Echo Requests Received — The number of Echo Request messages received.
Echo Requests Sent — The number of Echo Request messages sent.
Echo Responses Received — The number of Echo Response messages received.
Echo Responses Sent — The number of Echo Response messages sent.
Data Record Requests — The number of Data Record Request messages received by the CGF node.
Data Record Responses — The number of Data Record Response messages received by a GTP' node.
Redirect Requests — The number of Redirect Request messages received.
Redirect Responses — The number of Redirect Response messages sent.
The following measurements report the number and type of errors encountered during message exchanges.
Node Alive Timeouts — The number of times an expected Node Alive Response was not received.
Echo Timeouts — The number of times an expected Echo Response was not received before the Retry Interval expired. If Retries is enabled, the node will sent another Echo Request message.
Data Record Timeouts — The number of times an expected Data Record Transfer Response was not received.
Error Indication Received — The number of Data Record Response messages received with an error indication.
Error Indication Sent — The number of Data Record Response messages sent with an error indication. An error indication can be caused by a malformed GTP' payload, duplicate or a missing GTP' sequence number, or a Version Not Supported error. A No Resources Available error is sent if the number of Maximum Data Records has been achieved and an attempt is made to establish a new Data Record.
Invalid Messages — The number of packets received that contained an unknown protocol type or an invalid IP checksum.
Version Not Supported — The number of times a Version Not Supported error indication was sent or received.
