Abstract

The present disclosure recites techniques for correcting errors occurring in a multicast session. Precisely, the disclosure recites periodically receiving, data packets, comprising metrics including the existence of packet error, corresponding to a single multicast session, from plurality of client devices placed across one or more zones. The disclosure further recites selectively disabling a Not-Acknowledge (NACK) setting for each of the plurality of client devices using the metrics. Additionally, the method recites selectively enabling a Forward Error Correction's (FEC) setting for each of the plurality of client devices using the metrics.
