Chapter 3 Using IPM to Measure Network Performance
Measuring Network Performance for SNA
Figure 3-18 IP Path Echo Combined Hop List Window
It is easier to compare different paths and hops when viewing combined statistics.
To return to separate graphs for each path or hop, select View > Show Separate.
For more detailed information about the statistics displayed in the Path Echo Historical Statistics
window, see the “Path Echo Historical Statistics Window” topic in the online help.
Measuring Network Performance for SNA
For SNA environments, IPM allows you to measure the round-trip latency to an MVS mainframe using
the following types of SNA sessions:
• System services control point-logical unit (SSCP-LU)
• LU 0
• LU 2
Since SNA is a connection-oriented protocol, the only type of measurement you can request is Echo.
When measuring latency to an SNA mainframe, IPM measures round-trip latency between a source
device and an echo response program running on an SNA mainframe.
You can install NSPECHO, a program provided by IPM, on an MVS mainframe to provide the echo back
to the router.
