Determination of packet loss locations

摘要

In one embodiment, a system may determine receiver identifiers to identify affected receivers, where each of affected receivers failed to receive a packet identified within a packet stream. A loss signature may identify the packet. Each of the affected receivers may be identified by a corresponding one of the receiver identifiers. The system may also determine a packet loss location of the packet from a network topology tree. The network topology tree may include a model of a logical network over which the packet stream was transmitted from a stream source to the affected receivers. The packet loss location may correspond to a lowest common ancestor node of at least two of the affected receivers.
