The network education resource sharing is an important aspect in the higher education information technology construction. At present, the integration of universities institutes makes the network education resources development and application of the secondary institute extremely uneven. Grids are the use of technology to allow distributed resources to be effectively shared across diverse collaborations...
The management of manufacturing recourses is discussed for realizing distributed networked manufacturing, the multi-goal evaluating model is put forward. The factors and process in networked manufacturing resources evaluating are given, and the service function and the system architecture of Internet of Things is set up. It is useful to actualize area networked manufacture.
Network Virtualization is a promising way to overcome the weaknesses of the current Internet. However, how to solve the problem of the management and control of the virtual resources to obtain efficient resource utilization faces great challenges. In this paper, we propose a management framework of multi-domain and hierarchy to reduce the complexity and improve the efficiency of virtual resources...
Network Virtualization is a promising way to deploy future network architectures supporting diverse virtual networks sharing the substrate network. But the increased flexibility poses a daunting challenge to the management and control of the virtual resources to ensure efficient resource utilization and QoS guarantee. In this paper, we propose an architecture based on a hierarchical and multi-domain...
Cloud platforms enable enterprises to lease computing power in the form of virtual machines. An important problem for such enterprise users is to understand how many and what kinds of virtual machines will be needed from clouds. We formulate demand for computing power and other resources as a resource allocation problem with multiplicity, where computations that have to be performed concurrently are...
Cloud computing represents a promising computing paradigm where computing resources have to be allocated to software for their execution. Self-manageable Cloud infrastructures are required to achieve that level of flexibility on one hand, and to comply to users' requirements specified by means of Service Level Agreements (SLAs) on the other. Such infrastructures should automatically respond to changing...
Recently, due to the spread of broadband access to the Internet, the speeding up JavaScript on Web browsers and the development of communication technology such as Ajax, a variety of Web applications are provided. However, the access congestion to the Web server and the lower usability in case of higher frequent communication are major problems on the Web application. We have investigated the bottleneck...
With the rapid development of Internet and Cloud computing, there are more and more network resources. Sharing, management and on-demand allocation of network resources are particularly important in Cloud computing. Platform as a Service (PaaS) is one of the key services in Cloud computing. PaaS is very attractive for schools, research institutions and enterprises which need reducing IT costs, improving...
This paper presents the use of Augmented Reality technics exploiting distributed geographical information in a mobile device using wireless network. Our system offers useful informations (number of parcel, name of the owner, agronomic structure, juridical state, and adequate plant) related to each parcel geo-referenced according to the user's position and orientation. We used inertial sensor MTi and...
The successful implementation of knowledge management system in many firms has shed light to the possibility of its application to the E-learning for higher education in Chinese context. Based upon knowledge management theory and in-depth analysis of functions of knowledge management system, this paper illustrates the key problems faced by E-learning in Chinese higher education, and build a knowledge...
In this paper we introduce a Web based real time resource allocation tool that can assist the incident commanders and resource managers in the complex task of resource allocation and transportation for multiple simultaneous incidents that occur in close geographical proximity. The tool takes real time inputs like the location of emergency sites and damaged routes from Google Maps, generates an optimal...
We address two issues in this work: on one hand, we consider and compare five throughput predictors to be used in a Web system in order to estimate its future performance and, on the other hand, we propose an adaptive QoS-aware admission control algorithm that is based on a resource allocation scheme that includes a throughput predictor. In order to obtain a low overhead, the monitoring of the arrival...
The most commonly used request processing model in multithreaded web servers is thread-per-request, in which an individual thread is bound to serve each web request. However, with the prevalence of using template techniques for generating dynamic contents in modern web servers, this conventional request processing model lags behind and cannot provide efficient resource management support for template-based...
It is common that Internet service hosting centres use several logical pools to assign server resources to different applications, and that they try to achieve the highest total revenue by making efficient use of these resources. In this paper, multi-tiered enterprise systems are modelled as multi-class closed queueing networks, with each network station corresponding to each application tier. In...
Internet GIS is the cyber-infrastructure framework for geographic information services utilizing both wired and wireless Internet to access geographic data and spatial analytical tools. It has been developed and used extensively in many real-world applications. However, communities lacking of resource and expertise are denied due to its cost and technical complexity. Also users requiring tailored...
In order to solve the problem of resources sharing from different servers on the Internet or Intranet, a distributed resources sharing platform based on HBWSP and XML has bean designed and implemented in this paper. Developed in Java programming language with XML as its way of resources organization, this platform has implemented dynamic communication among different servers making use of distributed...
State-of-the-art cluster-based data centers consisting of three tiers (Web server, application server, and database server) are being used to host complex Web services such as e-commerce applications. The application server handles dynamic and sensitive Web contents that need protection from eavesdropping, tampering, and forgery. Although the secure sockets layer (SSL) is the most popular protocol...
