How does IPM measure latency between routers in the SNA environment?
In the SNA environment, IPM uses an SNA ping. The IPM application includes a component that runs on the mainframe. The router component of IPM sends a block of data (the request) to the mainframe component, which responds with a block of data (the response). Both the request and response sizes can be customized by the user so that traffic flow for various applications can be modeled. IPM supports the “SNA ping” over dependent logical unit (LU) sessions. IPM also measures SNA latency from a router to the mainframe over a system services control point (SSCP)-LU session. For these types of sessions, the mainframe component of IPM is not necessary. In this scenario, IPM uses an SNA ECHOTEST to solicit an SNA REQECHO from the mainframe over the SSCP-LU session. Cisco recently announced a partnership with Concord. The Concord Network Health application will generate reports based on the same SAA feature used by IPM. Should I purchase IPM or Concord Network Health? IPM and Concord Network Hea
