<p>Network quality monitoring system and method with zero traffic consumption are provided, based on a universal network architecture including a physical layer, network layer, transport layer, and application layer. The transport layer includes a heartbeat packet transmission and reception protocol module and heartbeat information, and the application layer includes an internet protocol module and its sequence numbers and timestamps. The heartbeat information, sequence number, and timestamp are parts of a network data stream with normal overhead. The disclosure focuses on heartbeat packets and internet protocol packets, performing statistical calculation by configuring reasonable heartbeat frequency and a statistical period to obtain a network packet loss rate, network delay, and network jitter during the statistical period, thus detecting network quality timely. Some embodiments can be applied to avoid burdening network traffic, and provide reliable, useful indications of network packet loss rate, network delay, and network jitter.</p> |
