Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for measuring network packet loss in IP-based networks are inadequate for point-to-multipoint or multipoint-to-multipoint networks, as they cannot accurately assess packet loss across multiple transmission paths, lacking a comprehensive measurement approach.
Innovation Solution
A method and system that involve data packet measurement information acquisition by Target Logical Ports (TLPs) and transmission to a Measurement Control Point (MCP), using measurement period identifiers, traffic stream identifiers, and data packet count values to determine network packet loss, enabling accurate measurement across various network topologies.

1Adaptability or versatility
If packet loss measurement is performed using prior art methods based on upstream transmitting point and downstream receiving point, then point-to-point network packet loss can be measured, but point-to-multipoint and multipoint-to-multipoint network packet loss cannot be measured
Solution Approach 1:
The network measurement function is segmented into multiple independent TLPs (Target Logical Ports) distributed at different network nodes. Each TLP independently measures packet loss for its received traffic streams, and results are aggregated at the MCP. This segmentation enables the system to handle complex multi-point topologies by dividing the measurement task across multiple network locations rather than requiring a single end-to-end measurement path.
Solution Approach 2:
The TLP and MCP architecture is designed as a universal measurement framework that can handle multiple network topologies (point-to-point, point-to-multipoint, multipoint-to-multipoint) through the same basic mechanism. The system uses unified data structures (measurement period identifier, traffic stream identifier, data packet count value, TLP identifier) and processing logic that adapts to different topology types without requiring separate measurement methods for each case.
2Measurement precision
If multiple TLPs are used to measure packet loss in multipoint networks, then comprehensive packet loss measurement across multiple paths can be achieved, but the complexity of data collection and processing increases
Solution Approach 1:
The MCP (Measurement Control Point) serves as an intermediary that centralizes the collection, correlation, and processing of measurement data from multiple distributed TLPs. Instead of requiring complex peer-to-peer coordination between TLPs, the MCP receives standardized measurement reports from each TLP, correlates data using unique identifiers (measurement period identifier, traffic stream identifier, TLP identifier), and computes comprehensive packet loss statistics. This intermediary architecture simplifies the overall system complexity by providing a single point of data aggregation and analysis.
Solution Approach 2:
The system uses standardized parameter structures for measurement data collection that simplify processing despite the complexity of multi-TLP operations. Each TLP reports using a fixed set of parameters (measurement period identifier, traffic stream identifier, data packet count value, TLP identifier), which allows the MCP to uniformly process data from any number of TLPs without increasing processing complexity proportionally. This parameter standardization enables scalable measurement across multiple network points.

AI summary
Provided are a method, apparatus and system for measuring network packet loss, the method includes: acquiring data packet measurement information measured by at least one target logical port to a traffic stream, transmitting the data packet measurement information to a measurement control point, so that the measurement control point determine the condition of network packet loss according to the data packet measurement information. As a data collecting point acquires the data packet measurement information measured by at least one target logical port to the traffic stream, and uniformly transmits the data packet measurement information to the measurement control point, when multiple target logical ports respectively perform measurement to acquire respective data packet measurement information, the measurement control point uniformly determines condition of packet loss of the traffic stream. Therefore, accurate packet loss measurement can be performed on the traffic stream under the scenario of point-to-point, point-to-multipoint or multipoint-to-multipoint networks.
