The “VM Turntable” demonstrator at iGRID 2005 pioneered the integration of Virtual Machines (VMs) with deterministic “lightpath” network services across MAN/WAN. The results provide for a new stage of virtualization—one for which computation is no longer localized within a data center but rather can be migrated across geographical distances, with negligible(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)
-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)
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 networks cannot provide dedicated links with adequate end-to-end sustained bandwidth to support the requirements of these Grid applications. DWDM-RAM is a novel(More)
We realize an open, programmable paradigm for application-driven network control by way of a novel network plane — the “service plane” — layered above legacy networks. The service plane bridges domains, establishes trust, and exposes control to credited users/applications while preventing unauthorized access and resource theft. The Authentication,(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)
Authentication, Authorization and Accounting (AAA) mechanisms have an increasingly versatile role when performing access control on various types of network resources. Emerging data intensive grid applications generate new network requirements. These requirements call for (pre-) allocate-able data transport facilities serving specific user communities. The(More)
Traditional IP accounting infrastructures cannot withstand the shock waves produced by voice over IP integration, increasingly large accounting data volumes, adaptive pricing schema that reflect resource utilization, and real-time requirements on accounting applications such as billing and traffic monitoring. To suit tomorrow’s networks, the Active IP(More)
