Network Node Operating Status Detection via Packet Quantity Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multimedia data real-time transmission scenarios, existing technologies cannot determine the operating status of each network node, leading to delayed fault maintenance and reduced transmission efficiency.
Innovation Solution
A method and apparatus that select a node on a transmission link, send a detection instruction, receive a real-time control packet and IP data packets, determine the necessary IP data packets based on the packet quantities, and assess the node's status using a threshold and quantity difference, allowing for quick and accurate determination of node operating status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If RTCP packets are used to monitor RTP packet transceiving situation, then dynamic network status information is provided, but the operating status of each network node cannot be determined
Solution Approach 1:
The patent segments the network monitoring function by introducing intermediate network nodes that independently report their forwarding status. Instead of relying on end-to-end RTCP packets alone, each network node along the transmission path is divided as an independent monitoring point that collects and reports local packet forwarding data, enabling granular node-level status detection.
Solution Approach 2:
The patent introduces network nodes as intermediaries between the transmit end and receive end. These intermediate nodes act as mediators that not only forward RTP packets but also collect and report their own forwarding statistics to a monitoring system, providing indirect observation of node operating status that complements direct end-to-end monitoring.
2Productivity
If only RTP packet transmission speed adjustment is performed based on RR packet data, then congestion control is achieved, but fault maintenance of nodes is delayed
Solution Approach 1:
The patent implements preliminary monitoring of node operating status by continuously collecting packet forwarding statistics from each network node before faults manifest as transmission failures. The system proactively detects abnormal node status through real-time packet quantity analysis, enabling early fault detection and maintenance scheduling before they impact multimedia transmission quality.
3Adaptability or versatility
If statistical information is collected at transmit and receive ends, then congestion control is enabled, but node-level transmission details are lost
Solution Approach 1:
The patent makes network nodes multi-functional by enabling them to simultaneously perform their primary function of forwarding RTP packets and a secondary monitoring function of collecting and reporting their own packet forwarding statistics. This universal approach allows the same network infrastructure to serve both data transmission and network monitoring purposes without requiring separate dedicated monitoring devices.

AI summary
A method and an apparatus for detecting an operating status of a node is provided. The method is as follows: selecting, from nodes of a transmission link established between a transmit end and a receive end, one node in the nodes as a to-be-detected node, and sending a detection instruction to the to-be-detected node; receiving a real-time control packet and a first quantity of IP data packets forwarded by the to-be-detected node, where the real-time control packet and the first quantity are returned by the to-be-detected node based on the detection instruction; determining, according to the real-time control packet, a second quantity of IP data packets that the to-be-detected node needs to bear; and obtaining a specified threshold and a quantity difference between the first quantity and the second quantity, and determining an operating status of the to-be-detected node according to the quantity difference and a value of the threshold.
