摘要
随着计算机和网络技术以及应用的不断快速发展,计算模式从最初的以主机计算为主,发展到以桌面(PC)计算为主,再发展到现在的以网络计算为主,乃至普适计算。然而,迄今为止的计算模式还是遵循以单机或单机联合为基础的单机思维模式,因此,目前的计算模式还是一种以"资源共享"为主要特征的计算。在网络和普适计算的新时代,用户关心的主要是服务和服务共享,计算机也将从以"资源共享"为特征的计算过渡到以"服务共享"为特征的计算。笔者提出一种适应于"服务共享"的计算模式——透明计算,并对其概念、体系结构及相关关键技术进行介绍。此外,还对透明计算的未来发展及影响进行展望。
With the rapid development of computer and network technologies, the computing paradigm has evolved from the original mainframe computing to desktop （PC） computing, and then to network computing, and even pervasive computing. However, the existing computing paradigms all follow the thinking model of single machine or joint-based single machine and thus are characterized as resource sharing. In the new era of network or pervasive computing, users are mainly concerned about services and service sharing, and accordingly the computing will also shift from being characterized as resource sharing to service sharing. This paper proposes a new computing paradigm, transparent computing, which aims for service sharing and presents the concept, architecture and key technologies of transparent computing. Moreover, it also gives the prospect of the impact and future development of transparent computing.
