Data structure providing storage and bandwidth savings for hardware RTCP statistics collection applications

Abstract

Data structures for efficient tracking Real-Time Control Protocol (RTCP) statistical information reported in connection with a Real-Time Protocol (RTP) encapsulated data stream, and a signaling protocol for updating corresponding statistical information between a hardware statistics information collection function and a software statistics information processing function is presented. Hardware data structure and software data structure specifications take into account: the arrival rate of RTCP statistics reports, the rate of generation of RTP packets, expected communication session duration, statistics information processing bandwidth, etc.; to provide a balance between hardware statistics information tracking, timely update of statistics information processed by software, while reducing statistics information update overheads in support of high density data streaming solutions.
