The replica consistency detection of text images is of great significance in office automation. For example, it can be applied to detect the consistency of the printed documents of commercial contracts and the original electronic documents. In this paper, we propose a method for replica consistency detection of text images based on multi-feature assessment. Firstly, we make a photocopy of the printed...
With the development of network technology, the high-speed networks with 1Gbps, 10Gbps and even higher bandwidth have emerging. In the traditional IP networks, TCP protocol performs well, However, in fast long distance networks (FLDnet), TCP's slow start and its Additive Increase Multiplicative Decrease (AIMD) congestion control are too conservative to make full use of the abundant bandwidth resource...
This paper designs the ScGridBroker as an scheduler of ScGrid that uses grid technology for managing large-scale distributed resources based on Economic Scheduling Algorithms. It discusses a layered and component-oriented modular architecture for the broker design and development. The architecture is generic enough to leverage services provided by various Grid middleware systems such as Globus, Legion,...
The short utility lifetime of performance monitoring information is an important consideration in the design of grid monitoring architecture. Disseminating fresh performance information quickly and accurately to satisfy thousands of potential requests is a challenge for Information Service. We propose a request scheduling mechanism that considers the indexes and urgency of information request. This...
Monitoring gird resources using Web Service is an important issue in grid computing. Although some concern has been given to the Index Service scalability with increasing grid resources, the overhead of processing thousands of resource information requests may cause performance problems in Index service for grid monitoring. This paper proposed a replica scheduling mechanism based on load balancing...
