Method for comprehensively evaluating network performance based on subjective and objective combination evaluation

Abstract

The invention relates to a method for comprehensively evaluating network performance based on subjective and objective combination evaluation, which comprises the following steps: A, selecting a comprehensive evaluation index of the network performance, collecting network performance data, and establishing a decision matrix; B, evaluating the network performance by using a subjective analysis method, and calculating the comprehensive evaluation value of the network performance; C, evaluating the network performance by using an objective analysis method, and calculating the comprehensive evaluation value of the network performance; and D, performing combined evaluation on the comprehensive evaluation values obtained by the subjective and the objective analysis methods respectively to obtain the final comprehensive evaluation value of the network performance. The method has the advantages that probable insufficient data information content by singly using the objective analysis method is avoided, subjective randomness caused by singly using the subjective analysis method is also avoided, and simultaneously, the subjective and the objective analysis methods are combined together to evaluate the network performance so that the evaluation is more scientific and comprehensive, and the method has reasonable design and strong practicability and provides a basis for monitoring and evaluating the practical network performance.

Description

technical field [0001] The invention relates to a comprehensive evaluation method of network performance, which is used for rationally, comprehensively and comprehensively evaluating network performance, and serves as a reference for scientific decision-making, belonging to the technical field of network communication. Background technique [0002] With the increasing importance of the network and the increasingly complex network structure, people's requirements for network quality of service (QOS) are also increasing. More and more network users and network management developers are concerned about the reliability, stability and efficiency of computer networks and many other aspects of performance. Therefore, network performance analysis and evaluation technology emerges as the times require. [0003] Currently, the definition of network performance indicators has not been standardized. In the world, there are two main organizations conducting research on network performa...

Problems solved by technology

[0006] At present, the analysis and evaluation of network performance mainly focus on the performance analysis of network protocols or algorithms, and what is involved is often only a specific performance index. However, when evaluating the performance of the actual or designed network itself, a single Metrics sometimes do not reflect the overall performan
