Network virtualization can effectively establish dedicated virtual networks to implement various network ***,the existing research works have some shortcomings,for example,although computing resource properties of individual nodes are considered,node storage properties and the network topology properties are usually ignored in Virtual Network(VN)modelling,which leads to the inaccurate measurement of node availability and *** addition,most static virtual network mapping methods allocate fixed resources to users during the entire life cycle,and the users’actual resource requirements vary with the workload,which results in resource allocation *** on the above analysis,in this paper,we propose a dynamic resource sharing virtual network mapping algorithm named NMA-PRS-VNE,first,we construct a new,more realistic network framework in which the properties of nodes include computing resources,storage resources and topology *** the node mapping process,three properties of the node are used to measure its mapping ***,we consider the resources of adjacent nodes and links instead of the traditional method of measuring the availability and priority of nodes by considering only the resource properties,so as to more accurately select the physical mapping nodes that meet the constraints and conditions and improve the success rate of subsequent link ***,we divide the resource requirements of Virtual Network Requests(VNRs)into basic subrequirements and variable sub-variable requirements to complete dynamic resource *** former represents monopolizing resource requirements by the VNRs,while the latter represents shared resources by many VNRs with the probability of occupying resources,where we keep a balance between resource sharing and collision among users by calculating the collision *** results show that the proposed NMAPRS-VNE can increase the average acceptance rate and network revenu

A Peer-to-Peer resource sharing Scheme Using Trusted Computing Technology

引用

Wuhan University Journal of Natural Sciences 2008年第5期13卷 523-527页

作者： CHEN Lu ZHANG Huanguo ZHANG Liqiang LI Song CAI Liang School of Computer Wuhan University/Key Laboratory ofAerospace Information Security and Trusted Computing of Ministryof Education Wuhan 430072 Hubei China State Key Laboratory of Software Engineering WuhanUniversity Wuhan 430072 Hubei China Department of Information Security Information EngineeringUniversity Zhengzhou 450004 Henan China

Facing the increasing security issues in P2P networks, a scheme for resource sharing using trusted computing technologies is proposed in this paper. We advance a RS-UCON model with decision continuity and attribute mutability to control the usage process and an architecture to illustrate how TC technologies support policy enforcement with bidirectional attestation. The properties required for attestation should include not only integrity measurement value of platform and related application, but also reputation of users and access history, in order to avoid the limitation of the existing approaches. To make a permission, it is required to evaluate both the authorization and conditions of the subject and the object in resource usage to ensure trustable resources to be transferred to trusted users and platform.

resource sharing by the Different Clonal White Clover Plant(Trifolium repens L.)

Journal of Northeast Agricultural University(English Edition) 1997年第2期4卷 110-115页

作者： Hu Baozhong, Liu Di, Wang Shiping, Teng Bing (Northeast Agricultural University, Harbin, 150030 PRC)

resource sharing in the different parts of the clonal white clover plant (Trifolium repens L.) was investigated in this study. The results showed that the integration of water and nitrogen metabolism occured among parental, young and old branches of a plant when water passed through its stolons. Under the sufficient supply of light, water and nutrients from soil the newly developed branches showed similar capacity in taking in sufficient water and nitrogen to that of old branches. The development of the new branches did not affect the growth of the old and parental branches attached. The results also indicated that energy values in roots was significantly related with plant age, however, the energy values were various in the different parts of a plant.

A Scalable resource Management Architecture for Wide-Area Industrial Measurement Collaboration on Grids

引用

International Journal of Plant Engineering and Management 2007年第1期12卷 1-17页

作者： ZHANG Deng-pan HE Ling-song YANG Hong School of Mechanical Engineering Huazhong University of Science and Technology Wuhan 430074 P. R. China

Research on Web measurement and industrial collaboration in measurement fields in a wide-area and across-organizationally is accepted globally. This paper proposes a novel, scalable management architecture of measurement resources for the resource organization and resource access of the current wide-area collaborative measurement applications in the context of a grid. The complexity of the measurement management on a grid arises from the scale, dynamism, autonomy, heterogeneity, and distribution of the measurement systems and the relative data systems. This paper mainly discusses the interconnection, collaboration, and transparent access of the multi-measurement resources based on the proposed management architecture in the context of complexity. We first discuss the logical architecture used in the measurement fields, and then the resource management system is put at a high premium with layered architecture. Finally, the problems such as resource interconnection, sharing and collaboration are studied in the context of the proposed management environment. The typical applying instance is given to show the advancement of the proposed approach.
