Claim 14:
15. A method implemented at least in part by a router of a multicast data flow, the method comprising:
receiving, from a downstream router of the multicast data flow, an instruction to begin monitoring incoming traffic of the multicast data flow, wherein the instruction is based on receiving by the downstream router an indication that an application executing on an end user device has identified a multicast data flow that is experiencing traffic loss;
monitoring incoming traffic of the multicast data flow;
at least partly in response to determining that an expected amount of the incoming traffic of the multicast data flow is being received at the router, transmitting to a network administrator device, a message indicating a network fault is occurring at a location of the router in the multicast data flow; and
at least partly in response to determining that an expected amount of the incoming traffic of the multicast data flow is not being received, sending to an upstream router of the multicast data flow, an instruction to begin monitoring incoming traffic of the multicast data flow.
