Remote-sensing image processing applications demand large-scale, collaborative processing and storage capabilities. Computational grid can provide abundant powerful computational resources with sharing and cooperation in grid environment. This paper gives an introduction to a collaborative processing mechanism based on workflow technology implemented in Imagegrid. The main idea is to encapsulate all parallel algorithms of remote-sensing image processing into grid services and recombine them with grid workflow to satisfy more and more complex remote-sensing image processing applications. In particular, we describe the architecture of the workflow-based grid system and the processing flow. We also give out the algorithm classification and an example of remote-sensing image processing grid application.

The emerging grids need an efficient replica location mechanism. In the experience of developing Chinagrid supporting platform (CGSP), a grid middleware that builds a uniform platform supporting multiple grid-based applications, we meet a challenge of utilizing the properties of locality in replica location process to construct a practical and high performance replica location mechanism. The key of the solution to this challenge is to design an efficient replica location algorithm that meets above requirements. Some previous works have been done to build a replica location mechanism, but they are not suitable for replica location in a grid environment with multiple applications like Chinagrid. In this paper, we present a novel peer-to-peer algorithm for replica location mechanism, Boundary Chord, which has the merits of locality awareness, self-organization, and load balancing. Simulation results show that the algorithm has better performance than other structured peer-to-peer solutions to the replica location problem.

grid technology provides the mechanism for large-scale sharing of computing resources, storage resources and equipments within virtual organizations crossing different administrative domains. Chinagrid project, founded by Ministry of Education of China, is an attempt to achieve above goals by exploring the various resources on existing and well developed Internet infrastructure, CERNET (China Education and Research Network). In this paper, we introduce the current status of Chinagrid project, and its driven requirements and architecture. The brief introduction of the design of Chinagrid Support Platform, named CGSP, is also given. To illustrate the impact of Chinagrid project, five different gridcomputing applications and its application supporting platform are discussed in detail

Network forensics and honeynet systems have the same features of collecting information about the computer misuses. Honeynet system can lure attackers and gain information about new types of intrusions. Network forensics system can analysis and reconstruct the attack behaviors. These two systems integrating together can help to build an active self-learning and response system to profile the intrusion behavior features and investigate the attack original source. In this paper, we present a design of honeynet based active network intrusion response system. The features of our system are distributed adaptive network forensics and active real time network investigation. Copyright 2005 ACM.

To defend the IP spoofing and differentiate IP address in the network intrusion detection system and DDoS defense system, we give a novel approach Recursion Nearness to characterize the IP address features, which is also helpful to the other security applications, such as firewall log analysis, traffics filter rule management, intrusion investigation and IP trace back. We characterize the IP address with some fields, such as TTL, MAC, TCP/IP stack implementation fingerprinting and IP geographic location mapping. Major implementation approaches to the system are discussed and given. Experiment results of our system show that this method can characterize IP features more exact and efficiently.

Resource information service, as a key component of grid, is the basis of the resource allocation, resource performance evaluation and prediction. The validity of the resource information service directly influences the availability of the whole system. One of key points to make information service work well is the precise of the information collected, how to get the valid system information with low system cost has became a difficult problem in current information service. In this paper, we propose hybrid resource information service architecture based on grid monitoring architecture to promote the validity of the resource information service in grid. HRIC is an improved information service architecture that utilizes resource changing self-monitoring mechanism to offset the blind spot of the periodical information collection and combine the advantages of two traditional information collection methods - periodic collection and stochastic reporting, thereby improving the accuracy of resource information service. Compared with the existing resource information systems, HRIC's performance has been validated by several applications
