The Multicast Tester is a simple tool for users to test their IP Multicast connectivity. This instance of the tester is provided as a general purpose tester. It operates by listening for traffic from the NLANR Multicast Beacon project. The Java security model requires the applet to request permission before it can perform certain restricted actions. Testing your IP Multicast connectivity requires you to grant several privileges to the Applet. Click the button below to begin the test.
