Service-oriented Layer 1 Virtual Private Network for Grid Applications
نویسندگان
چکیده
Emerging data-intensive Grid applications call for service-oriented layer 1 virtual private networks (VPNs) as their data plane. Layer 1 VPNs are created by dividing a physical network into web service enabled partitions. In this paper, we introduce the concept of fundamental lightpath, and propose that a fundamental lightpath be taken as the basic unit of optical network partitions. We then enlist the key web service operations a Lightpath Web Service (LP-WS) should support, such as concatenation, partitioning, etc. Furthermore, we discuss the LP-WS in the context of a business process, where institutions involved in a collaborative Grid project acquire a pool of LP-WSs from optical carrier networks, and then integrate these LPWSs with discipline-specific web services into a workflow.

Quality of Service delivered to Grids by packet-switched networks, is one of the most important factors affecting performance and efficiency of both Grid applications and middleware. The use Virtual Private Network services can improve the overall performance of Grids in many respects. In this paper, we show how the security, privacy and Quality of Service offered by scalable on-demand VPN serv...
متن کاملWorkpackage 9 Grid-enabled Scientific Libraries A conceptual model for grid-adaptivity of HPC applications and its logical implementation with components technology
Today grid middleware is complex to be used, the development of grid-aware applications is errorprone and the Virtual Organization grid paradigm contrasts with traditional HPC optimisation strategies based on resource stability and known cost models of inter-node interaction patterns. The authors analyse several aspects of grid adaptivity, and identify 5 roles: the active resource/execution man...
متن کاملIntroducing Virtual Private Overlay Network Services in Large Scale Grid Infrastructures
The computational Grid concept is gaining great popularity as the best way to deliver access to a wide range of distributed computing and data resources. But, as Grids move from an experimental phase to real production and their deployment in the Internet significantly increases, controlling the security of a Grid application becomes imperative. The most significant Grid security issue is that ...
متن کاملA Flexible Multi-layered Virtual Machine Design for Virtual Laboratories in Grid Systems
We propose a flexible Multi-layered Virtual Machine (MVM) design intended to improve efficiencies in grid computing and to overcome known problems that exist in grid systems. We present a novel approach to building virtual laboratories by adapting MVMs within distributed and grid systems, thereby providing enhanced flexibility and reconfigurability. The MVM is a service-oriented grid architectu...
