    OneTouch AT and OneTouch AT G2 User Manual Multicast (IGMP) Test Purpose The Multicast (IGMP) test verifies the ability to subscribe to an IGMP multicast group and verifies the flow of multicast data to the OneTouch analyzer. Multicasts are used for online streaming of data from devices such as security video cameras, industrial sensors, and ticker tape data.

  • Page 171: How It Works

    Chapter 5: User Tests Multicast (IGMP) Test How it Works The OneTouch analyzer joins the specified multicast group and listens for traffic. If a source address is specified, it will only listen for traffic from that IP address. The test runs in turn on each configured network connection.
