Index system constructing method for overall efficiency of network

Abstract

The invention discloses an index system constructing method for overall efficiency of a network. The index system constructing method comprises the following steps: S1, preliminarily drawing up a key index set, selecting key efficiency indexes and determining an index set; S2, refining same-layer indexes and calculating weight, and constructing weight factors of the efficiency indexes relative to the integral efficiency; S3, calculating cross-layer index weight, realizing index weight weighted calculation of a high layer relative to a layer adjacent to the high layer and further realizing index weight weighted calculation of a higher layer on the relative high layer, thereby forming an integral efficiency estimation function with weighted weight. According to the index system constructing method, integral efficiency of the network is estimated by selecting efficient indexes from different levels and different aspects, so that problems of one-sidedness, limitation and the like in a single performance index estimation process in the prior art are effectively solved, and the integral efficiency and the group efficiency of the system are reflected better.

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...
