A Method for Constructing Index System Oriented to Overall Network Effectiveness

Abstract

The invention discloses a method for constructing an index system oriented to overall network performance, which includes the following steps: step S1, drafting a set of key indexes, selecting key performance indexes, and determining the set of indexes; step S2, refining indexes of the same layer and calculating weights, Construct the weight factor of the performance index relative to the overall performance; step S3, calculate the weight of the cross-layer index, realize the weighted calculation of the index weight by the high-level relative to its adjacent low-level, and further realize the weighted calculation of the index weight by the higher-level relative to the high-level, forming a weighted Overall performance evaluation function. The present invention selects performance indicators from multiple levels and aspects to evaluate the overall performance of the network, effectively solves the problems of one-sidedness and limitations in the evaluation process of a single performance index in the prior art, and better reflects the overall performance of the system and the group efficacy.

Description

technical field [0001] The invention belongs to the field of network technology, and in particular relates to a method for constructing an index system oriented to the overall performance of the network, in particular to a method for selecting a hierarchical key index. Background technique [0002] Network performance assessment is one of the challenging topics in information system security assessment, and it is the fundamental basis and premise of network countermeasure research and implementation. The performance evaluation of the network includes three aspects: the selection of the evaluation index set, the specific evaluation method and the corresponding evaluation system. However, the current network performance evaluation faces many problems, such as multi-dynamic network environment, multi-parameter influencing factors and multi-indicator measurement criteria. First of all, network effectiveness evaluation is subject to the influence of various factors in the networ...
