CONTINUOUS DETECTION OF DEAD OR IMPAIRED IPTV STREAMS

摘要

The embodiments herein relate to a method and system for continuous detection of dead and impaired IPTV streams by introducing a hardware block to continuously monitor all IPTV streams for health without software intervention as disclosed in the embodiments herein. Each IPTV packet header is looked up in the multicast forwarding database (TCAM) table. When there are matching entries, the packets are metered and compared with the expected rate for the IPTV stream. A periodic scan of all the meters in hardware is carried out. If any stream is received less than its expected rate, an “impaired error” counter is incremented for the particular stream.

1. A method for monitoring health of an Internet Protocol Television (IPTV) Network in a continuous manner, said method comprising of
Metering each packet destined for an IPTV stream using a counter; Scanning said counter at a first predefined interval; Incrementing an impairment counter if said counter does not satisfy expected rate for said IPTV stream; and Scanning said impairment counter for health of said IPTV stream at a second predefined interval.
