With the rapid development of Internet technology, large-scale distributed systems can be widely used in various fields. However, the complexity of the system increased with the expansion of the system size, the system administrator must face greater challenges in management of these large-scale distributed systems. There is an urgent need to reform the traditional approach

With the rapid growth of the internet, new network technology emerges fast than ever. The problem between the need for computing resources and the fact of large un-used resource over the internet became more severe. The raise of National 973 project “Internet-based Virtual Computing Environment” (iVCE) wishes to provide massive resources for the need of

With the growing application area of network, it aroused more and more attention about the potential safety hazard brought by using it. However, the traditional defense methods cannot satisfy the demands of modern information network. More network managers find they can do nothing when all kinds of security schemes face to destroy information changed quickly.

As software complexity and malicious attacks continue increasing, dependability has now become one of the most serious challenges, but the traditional dependability which depends on designing more complex software to be dependable is not suitable. In this paper, based on the feature of self-awareness and self-management, autonomic computing is used to design a new kind
