Use case · Multicast assurance

Never lose a feed to a silent tree break.

Market-data feeds, IPTV and SCADA control all ride multicast — where a single missing branch silences receivers while every interface still reports "up." Phantom watches the tree itself.

How Phantom does it

The whole distribution tree, continuously.

Collect multicast groups and members, and full (S,G) mroutes — incoming interface, PIM neighbor, RPF and the outgoing-interface list.
Stitch mroutes across devices into a source-to-receiver path you can trace on demand.
Keep tree snapshots as history, so you can diff and see the exact branch and moment a feed thinned.
Alert the instant an outgoing-interface list empties or RPF points at a failed uplink.

Example

A trading desk loses group 239.1.1.5. Phantom shows the mroute healthy at the source and core, but empty at the distribution router with RPF pointing at a flapped uplink — the exact break point, found without walking every router.
