Abstract

The VNOD project aims to build an on-demand network virtualization infrastructure that can deliver the unprecedented networking performance and quality of service required by modern, distributed, data-intensive applications utilized by user communities. Recent networking technologies, already deployed in production and/or in experimental phases, offer the capability to dynamically provision network resources interconnecting multiple end sites hosting storage and computing resources. The VNOD infrastructure described in this paper leverages these technologies to provide an environment that facilitates the establishment and management of virtual network topologies. At the same time, VNOD also offers a platform for co-scheduling end-site resources with local and wide-area network resources through the use of various algorithms and optimization objectives.
