Software-Kernel of Software Network and S-Model Approximation During Software Growth

摘要

Because of the complexity in studies on software code and software network,the software-kernel of software network is defined and extracted to reduce the difficulty of grasping and measuring any software.Then a software-kernel layer stripping algorithm is developed to study the software-kemel with a certain amount of samples.The analysis results showed that the ordinal number of software-kernel layer of any software is directly proportional to the growth of that software,i.e.its upgrading evolution.The ratio of ordinal number of a kernel layer to the number of nodes of a software-kernel thus approximates to the S-model during the growth of software.Such a result is available to study the hierarchy of measuring softwares.Moreover.the extraction of software-kernel can be used to simplify the grasping of softwares and focus on the design,implementation and testing of key classes in softwares.
