The values on the MME Node tab report the processing measurements and throughput of the eNodeB/MME emulators or RNC/SGSN emulators (depending on the type Serving Node selected), the number and types of messages sent and received by the MME/SGSN Nodes, and MME/SGSN session measurements. The Measurements display in the SGW Nodal test case.
In MME Nodal test case, when Test Activity is Inter-MME Mobility, you select SGW/PGW Node Emulation and either select S10 Interface to MME or not, MME Node displays MME GTP Instance measurements.
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 all IP traffic processed by the node, including the Diameter, TCP, and IP layers:
Total Packets Sent — The number of IP packets sent.
Total Packets Received — The number of IP packets received.
Total Packets — The total number of packets processed by the node.
Total Packets/Sec — The data throughput rate as of the previous interval in packets per second.
Total Invalid Packets — The number of packets received that contained an unknown protocol type or an invalid IP checksum, and the number of times a peer attempted a connection when the maximum number of connections has been reached.
Total Fragments Sent — The number of fragmented data packets sent. By default, fragmentation occurs when the total bytes in the data packet exceeds 1400 bytes. You can control fragmentation by defining the MTU.
Total Fragments Received — The number of fragmented packets received.
Total Fragmented Packets Received — The total number of fragmented packets received. For example, if one IP packet was broken up into 3 fragments, the counter considers it as 1 fragmented packet.
Total Non-Fragmented Packets Received — The total number of non-fragmented packets received. That is, Total Packets Received - Total Fragmented Packets Received.
Total Fragmented Packets Sent — The total number of fragmented packets sent. For example, if one IP packet was broken up into 3 fragments, the counter considers it as 1 fragmented packet.
Total Non-Fragmented Packets Sent — The total number of non-fragmented packets sent. That is, Total Packets Sent - Total Fragmented Packets Sent.
Data Verify Attempts — The number of times a peer attempted to verify data.
Data Verify Successes — The number of times a peer succeeded to verify data.
Data Verify Failures — The number of times a peer failed to verify data.
Total Pings Received — The number of times a peer received a ping.
Total Pings Sent — The number of times a peer sent a ping.
Total Ping Replies Received — The number of ping replied received.
Total Bytes Sent — The number of bytes sent.
Total Bytes Received — The number of bytes received.
Total Bytes — The total number of bytes processed by the node.
Total Bits/Sec — The data throughput rate as of the previous interval in bits per second.
Echo Requests Sent — The number of Echo Request messages sent.
Echo Requests Received — The number of Echo Request messages received.
Echo Responses Sent — The number of Echo Response messages sent.
Echo Responses Received — The number of Echo Response messages received.
Heartbeat Requests Sent — The total number of Heartbeat Requests sent received.
Heartbeat Requests Received — The total number of Heartbeat Requests received.
Heartbeat Responses Sent — The total number of Heartbeat Responses sent.
Heartbeat Responses Received — The total number of Heartbeat Responses received.
Max Missing Heartbeat Req Exceeded — The number of Heartbeat Requests that exceeded the Maximum Number of Consecutive Heartbeat Requests allowed.
Total Sync Information Packets Sent — The total number of sync information packets sent.
Total Sync Information Packets Received — The total number of sync information packets received.
Total Sync with Data Packets Sent — The total number of sync with data packets sent.
Total Sync Information Packets Received — The total number of sync with data packets received.
When Dynamic IPSec is used to encrypt Diameter traffic, the following measurements provide general information regarding IPSec SA establishment. More detailed measurements can be found on the IPSec tab.
IPSec Attempts — The number of times a node attempted to negotiate an SA with the peer.
IPSec Successes — The number of successful SA negotiations.
IPSec Failures — The number of failed SA negotiations.
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.
IP Instance Handoff Time — The time when this IP instance is handed off to it's peer/another device.
