Example Embodiment

[0035] The method for dynamically predicting trusted attributes of network services provided by the present invention includes the following steps:

[0036] (1) Monitor multiple trusted attributes in the network service system at equal time intervals to obtain the corresponding monitoring values ​​of the trusted attributes, and obtain an initial monitoring tensor T′( T′ ijk ) N×M×L , Where L represents the total number of time periods divided into fixed time intervals, N represents the number of network services included in each time period, and M represents the number of trusted attribute types in the trusted attribute monitoring value. Each element T′ in the quantity T′ ijk Represents the monitored value obtained by the i-th network service on the j-th trusted attribute in the k-th time period, 1≤i≤N, 1≤j≤M, 1≤k≤L, for the tensor T′ The monitoring results of each credible attribute are normalized to obtain the normalized tensor T ijk :

Abstract

The invention relates to a network service credible attribute dynamic prediction method, and belongs to the technical field of computer software engineering. The method comprises the following steps:firstly, monitoring network service credible attributes, constructing credible attribute value tensors, decomposing the tensors by applying a weighted non-negative tensor decomposition method, and extracting time-related hidden characteristic factors; secondly, performing prediction of the next time period on the time-related implicit characteristic factor obtained after decomposition by applyingan exponential smoothing prediction method, and performing calculation estimation on a network service credible attribute value of the next time period; the method has the advantages that the time dynamic relationship of the network service credible attribute is utilized, and the prediction accuracy of the network service credible attribute is improved. The method does not depend on a specific credible attribute, is directly applied to a network service credible attribute monitoring result, and has very high flexibility and adaptability. A weighted non-negative tensor decomposition algorithm and an exponential smoothing algorithm are combined, so that the prediction effect of the method is improved.

Description

technical field [0001] The invention relates to a method for dynamically predicting trusted attributes of network services, which belongs to the technical field of computer software engineering. Background technique [0002] The service-oriented architecture is a distributed computing method, which gathers the computing power dispersed in various parts of the network to jointly perform a computing task, thereby reducing the construction cost and time overhead of the distributed system. Due to various reasons such as hardware, software, human operation, and network overload, the failure of network services is inevitable when performing services, which may greatly affect the user experience and suffer losses. The high-reliability requirements of network services require effective estimation and prediction of various attributes such as reliability, availability, and security, so that failure warnings or recovery measures can be taken in time. Especially with the rapid growth o...
