This paper presents ALTER, an adaptive failure detection service, which incorporates the technique of unreliable failure detection service and the idea of R-GMA. ALTER is organized in a hierarchical structure and it can be adaptive to the system conditions and user requirements with changing the system parameters and system organizations. With mathematical evaluation, ALTER shows good scalability and flexibility, which is suitable for grid environments. Copyright 2006 ACM.
grid information service influences quality of service for grid platforms directly. In this paper, based on network latency, network coordinate is introduced into grid information service to locate each grid node. By ...

The ability of worms to spread at high rate has made them an incredible security threat to modern networked computer systems. In addition, the rate of worms spreading has risen dramatically with the increasing in connectivity. Most prior works on defending against infection are focus on slowing down the infection rate after worms being detected during worms' propagation. A novel vaccine propagation architecture is proposed in this paper, named PropaV, that seeks to expedite the spreading of vaccines and depress the spreading rate of worms in distributed environment. PropaV demonstrates that distributing vaccine to most nodes as fast as possible after the vaccine has been published is also an effective way to restrain the worms spreading. This paper describes our system architecture, discusses challenges of various components, gives some simulation results and directions for future research

Due to the highly distributed and dynamic features, service discovery is a key requirement in gridcomputing. The paper first introduces the existing service discovery mechanisms in distributed computing, and then points out the problems in MDS which is widely used in gridsystems. In order to address these issues, GNSD, a novel service discovery mechanism is proposed, which is based on the OSPF (Open Shortest Path First) flooding mechanism and combines the advantages of tree architecture and flat architecture. The time and space complexity of both GNSD and MDS are also analyzed. Experimental results show that GNSD not only accelerates the service discovery but also relieves the burden of servers at the cost of little extra storage and communication traffic. Furthermore, it is more robust. As a conclusion, GNSD is an efficient service discovery mechanism
gridcomputing is emerging as a new format of wide area distributed computing. Because the distribution of services and resources in wide-area networks are heterogeneous, dynamic, and multi-domain, security is a criti...
