A number of customers in, for example, the Service Provider segment, the Media and Entertainment industry, etc. use networks to transport audio and video signals. These audio and video signals include uncompressed video transported in accordance with the Society of Motion Picture and Television Engineers (SMPTE) ST 2110 standards, compressed video in accordance with the Moving Picture Experts Group (MPEG) standards, JPEG 2000 (J2K), etc., which may be User Datagram Protocol (UDP)/Real-time Transport Protocol (RTP) flows in a network.
Today, when there is packet loss, end customers/operators find it very difficult to determine where the packet loss is happening in the network as, at times, the flows traverse different geographic regions, different service providers, etc. The techniques presented herein leverage flow tables on vendor Cloud Scale application-specific integrated circuits (ASICs) to detect gaps in RTP flows (i.e., to detect RTP packet drops). As soon as RTP packet drops are detected, the networking device (e.g., switch with the Cloud Scale ASIC) can generate an alert notifying the end customer/operator of the packet loss, thereby enabling the end customer/operator to pinpoint exactly where the loss is occurring.
