Signals used to test for upstream signal leaks in a hybrid fiber-coaxial (HFC) network may be interleaved with client data and strategically timed to be received by a leak detection device with a one-hundred percent probability of intercept. A method includes receiving an indication that a user device is in proximity to a computing device. The method includes determining, based on the indication that the user device is in proximity to the computing device, signal information. The method includes causing, based on the signal information, the user device to output a signal. The method includes determining, based on an indication that the signal was received by the computing device, a location of a network leak.

Methods and systems for determining signal leaks in a network

Systems, apparatuses, and methods are described for replicating data packets at individual compute (e.g., VCMTS) nodes and sending the replicated data packets to a gateway via a tunneling protocol. The gateway determines traffic data related to usage and telemetry based on the replicated data packets. Partial replication of the data packets, for example, replicating the headers only, may further reduce network I/O bandwidth and support higher customer scale. The partially replicated data packets may be used for data related to usage such as whether a user watched or interacted with content such as advertisements and provide basis for decision-making regarding the content.
