A method for refined dial testing and quality analysis of Ethernet aggregated links

Abstract

A method for refined dial testing and quality analysis of Ethernet aggregated links, capable of discovering link quality problems in time, improving the work efficiency of poor quality link analysis, and avoiding time-consuming and laborious manual statistics. It is characterized in that it includes the following steps: Step 1, clarify the data source, the data includes automatic collection of basic data and manual import of basic data; Step 2, collect link dial test indicators and establish a poor quality link analysis algorithm, and perform PING dial test analysis on aggregated links. Perform PING test analysis on the physical links of non-aggregated links, obtain the delay and packet loss rate of each tested link, and obtain the error code index and traffic loss index of each tested link; step 3, identify according to the identification algorithm For poor-quality links, the identification algorithm refers to identifying poor-quality links by setting preset values ​​for the comprehensive performance indicators of Ethernet links, and the comprehensive performance indicators use day granularity data as the measurement standard or minute granularity Data are for measurements.

Description

technical field [0001] The present invention relates to network quality analysis technology, in particular to a method for fine-tuning and quality analysis of Ethernet aggregated links, which can timely discover the quality problems of aggregated links, improve the work efficiency of poor-quality link analysis, and avoid manual statistics. It is time-consuming and labor-intensive, which is conducive to providing strong system support for the optimization and evaluation of the overall network. Background technique [0002] As the network scale continues to expand, users have higher and higher requirements for the bandwidth and reliability of backbone links. In traditional technologies, bandwidth is often increased by replacing high-speed port boards or network elements that support high-speed port boards. However, this solution requires high costs and is not flexible enough. [0003] Link aggregation (English: Link Aggregation) technology, also known as backbone technology (...

AI Technical Summary

Problems solved by technology

[0007] The inventors found that since the aggregated link balances and shields the problem of member links as a whole, and the aggregated link can only be monitored and analyzed as a whole by conventional means, indicators appear in each member link in the aggregated group Problems such as degradation cannot be detected and analyzed in a timely manner, let alone the quality of each member link within the aggregation link, which also brings some difficulties to operators' daily network maintenance.

For example, from the perspective of the current status of Ethernet networking and the management and maintenance of aggregated links, the existing problems and defects in the refined quality analysis of aggregated links are as follows: 1. There are a large number of network element nodes, the link relationship is complex, and a large number of aggregated links are used at the same time. If you rely on manual methods to maintain the entire network links and identify the corresponding relationship between aggregated links and physical links, data maintenance is difficult and the accuracy rate is low. ; On this basis, it is more difficult to analyze the quality of the aggregated links in the network

2. Most of the existing vendor’s network management monitors and maintains physical network elements and physical ports, and cannot monitor and analyze problems and quality degradation of aggregated links in a real-time and effective manner.

3. The traditional integrated network management can discover related alarms and quality indicators of aggregated links through SNMP collection and PING testing methods, but cannot refine the quality indicator analysis of specific member links
