VXDL: Virtual Resources and Interconnection Networks Description Language

Abstract

International audienceData grid applications require often an access to infrastructures with high performance data movement facilities coordinated with computational resources. Other applications need interconnections of large scale instruments with HPC platforms. In these context, dynamic provisioning of customized computing and networking infrastructure as well as resource virtualization are appealing technologies. Therefore new models and tools must be studied and developed to allow users create and handle such on-demand virtual infrastructures within grid platforms or even within the Internet. This work presents VXDL, a language for virtual resources interconnection networks specification and modeling. Besides allowing end resources description, VXDL lets users describe the desirable virtual network topology, including virtual routers and timeline. In this paper we motivate and present the key features of our modeling language. We explore typical examples to demonstrates the expressiveness and the pertinence of it. Then we detail experimental results based on the execution of NAS benchmark on virtual infrastructures, conforming different VXDL specifications

A Survey of Models for Computer Networks Management

“…The Virtual Resources and Interconnection Networks Description Language (VXDL) [88][89][90] originates from the Grid Computing area (like vgDL). Grid implementations present special operational characteristics -in a Grid environment it is imperative that resources involved can be dynamically re-allocated, without disturbing any running applications.…”

An evaluation testbed for adaptive, topology-aware deployment of elastic applications

“…The ADT provides a plugin mechanism for placement algorithms, offers a high-level interface to allocate geographically distributed resources as an allocation graph -similar to VXDL [3] -and automates common deployment tasks. The ADT collects topological data from the TM and provides them to the adaptation plugin, so topology-aware placement algorithms can use this data.…”

Architecting the Network for the Cloud using Security Guidelines

“…A virtual infrastructure [4] is a platform that is provided and managed by a cloud service provider using virtual resources to use the cloud resources by a cloud service consumer. A virtual infrastructure consists of server virtualization to gain access the resources carried out by a user, storage virtualization to store the information and access to the resources by a user, network virtualization to manage cloud network infrastructure and access the resources by a user.…”
