Grid networks enabling grids with advanced communication technology phần 4

Các chương đầu tiên của cuốn sách này giới thiệu các thuộc tính lưới và thảo luận làm thế nào những thuộc tính vốn có trong thiết kế kiến trúc lưới. Những chương mô tả các lợi ích của việc thiết kế nhiều nguồn lực trong một khuôn khổ các dịch vụ lưới như các mô-đun địa chỉ cho phép chức năng linh hoạt. | Chapter 5 Grid Network Services and Implications for Network Service Design Joe Mambretti Bill St. Arnaud Tom DeFanti Maxine Brown and Kees Neggers 5.1 INTRODUCTION The initial chapters of this book introduce Grid attributes and discuss how those attributes are inherent in Grid architectural design. Those chapters describe the benefits of designing multiple resources within a Grid services framework as addressable modules to allow for versatile functionality. This approach can provide for both a suite of directly usable capabilities and also options for customization so that infrastructure resources can be accessed and adjusted to match the precise requirements of applications and services. These chapters also note that until recently this multifaceted flexibility has not been extended to Grid networks. However new methods and architectural standards are being created that are beginning to integrate network services into Grid environments and to allow for more versatility among network services. Chapter 3 explains that the SOA used for general Grid resources are also being used to abstract network capabilities from underlying infrastructure. This architecture can be expressed in Grid Networks Enabling Grids with Advanced Communication Technology Franco Travostino Joe Mambretti Gigi Karmous-Edwards 2006 John Wiley Sons Ltd 82 Chapter 5 Grid Network Services and Implications for Network Service Design intermediate software that can provide for significantly more capability flexibility and adjustability than is possible on today s networks. This chapter presents additional topics related to the basic requirements and architectural design of Grid network services. The design of Grid network services architecture currently is still at its initial stages. The development of this architecture is being influenced by multiple considerations including those related to technology innovation operational requirements resource utilization efficiencies and the need to create .
