The "VM Turntable" demonstrator at SC05 and SC06 pioneers the integration of Virtual Machines (VMs) with deterministic "lightpath" network services ( across metro and wide area networks. The integration provides for a new stage of virtualization, one for which computation is no longer localized within a data center but rather can be(More)
Current network devices enable connectivity between end systems with support for routing with a defined set of protocol software bundled with the hardware. These devices do not support user customization or the introduction of new software applications. Programmable network devices allow for the dynamic downloading of customized programs into network(More)
Conventions such as iGrid 2005 and SuperComputing show that there is an increasing demand for more service options on networks. For such networks, large teams of experts are needed to configure and manage them. In order to make the full potential of hybrid networks available to the ordinary user, the complexity must be reduced. This paper presents the idea(More)
Advances in Grid technology enable the deployment of data-intensive distributed applications, which require moving Terabytes or even Petabytes of data between data banks. The current underlying nehvorks cannut provide dedicated links with adequate end-to-end sustained bandwidth to support ihe requirements of these Grid applications. DWDM-RAM' is a novel(More)
The Internet has seen an increase in complexity due to the introduction of new types of networking devices and services, particularly at points of discontinuity known as network edges. As the networking industry continues to add revenue generating services at network edges, there is an increasing need to provide a systematic method for dynamically(More)
A significant challenge arising from today's increasing Internet traffic is the ability to flexibly incorporate intelligent control in high performance commercial network devices. This paper tackles this challenge by introducing the Active Flow Manipulation (AFM) mechanism to enhance traffic control intelligence of network devices through programmability.(More)
Current network nodes enable connectivity between end-systems by supporting a static and well-defined set of protocols. The forwarding service provided by these network nodes is fixed, simple, and increasingly being implemented in hardware. Active network nodes, on the other hand, enable the unattended, dynamic instantiation of custom programs into the(More)
