【摘要】This paper analyzes the structure and property of hardware dependent folder named C and hardware independent folder named CPUKIT in RTOS RTEMS from the perspective of complex networks.Through calculating some properties of RTEMS from version 4.6.0 to 4.10.0,we found that the C folder and CPUKIT folder had \World\and \free\characteristics.At the same time,we calculated the number of nodes impacted by the changed nodes during the evolution of RTEMS.Furthermore,we defined a novel statistical measure called average bug propagation cost to characterize the structural quality of general complex software networks.%本文从复杂网络的角度分析了实时操作系统RTEM中与硬件相关的C文件夹和与硬件无关的CPUKIT文件夹的结构和性质。通过计算RTEMS从4.6.0到4.10.0共22个版本的一些参数,发现RTEMS的C文件夹和CPUKIT文件夹都具有＂小世界＂和＂无标度＂性质。同时本文也计算了RTEMS版本演化过程中节点变对RTEMS可维护性的影响,并采用一种定量度量软件可维护性的概念,平均故障传播代价,计算了RTEMS的CPUKIT各个版本的可维护性。 【总页数】3页(332-333,140) 【关键词】复杂网络;可维护性;RTEMS
