基于NNVD 的网络化软件多步控制算法研究

摘要

网络化软件系统规模的增大不仅增加了理解和优化系统的难度，而且一个小的异常就有可能引发整个系统的崩溃。因此，针对网络化软件系统的异常行为，本文提出一种基于NNVD(network node value degree)的网络化软件多步控制算法，该算法从节点路径长度范围的角度去研究异常行为传播的局域控制，通过网络化软件节点的重要程度选择控制节点，分析在无标度网络软件系统中进行局域多步控制的有效性。研究表明，该算法能够在一定程度上抑制异常行为的传播，使异常能够在一定的范围内得到有效的控制。%The increasing scale of networked software system not only increases the difficulty to understand and optimize the system,but a small anomaly is likely to cause the collapse of the whole system.Therefore,in view of the abnormal be-havior of networked software system,this paper proposed a networked software based on NNVD multistep control algo-rithm.The algorithm studied the spread of the abnormal behavior of local control from the perspective of the node path length range,and analyzed the local multistep control effectiveness in a scale-free network software system through the network selection to the importance of the control software node.The studies show that the proposed algorithm can restrain the spread of abnormal behavior to a certain extent,and can get effective control over the exceptions in a certain scope.
