We also evaluate the total time taken to generate and transmit short-term forecast images to end users with live data from our own radar on campus. We also compare the performance of each of these clusters for Nowcasting with commercial cloud services such as Amazon's EC2.

| | 1598 | <br><br><b>Abstract: </b>Software-Defined Networking (SDN) has been widely recognized as a promising way to deploy new services and protocols in future networks. The programmability and control offered by SDN networks enables users and applications to define virtually every aspect of the network architecture. Unfortunately, this flexibility comes at a cost - a cost that has the potential to significantly limit its adoption. First, in order to offer complete flexibility, today's SDN networks provide low-level API's on which almost any type of service can be written. In the process, it can actually become more difficult to implement the higher level complex services needed by future networks. Second, emerging SDN networks exhibit a heterogeneity reminiscent of the early Internet, with limited ability to piece together the various SDN platforms being deployed. In this paper we propose a new way to construct SDN networks consisting of multiple SDN providers offering virtualizable networking resources across the Internet. At the heart of our approach is a Network Hypervisor service that is capable of internetworking various SDN providers together. Moreover, our Network Hypervisor builds on the low-level APIs provided by SDNs to create a unified set of high-level abstractions and APIs that greatly simplify the task of building and deploying complex network services over SDN. |

| | 2954 | <br><br><b>Abstract: </b>A testbed capable of representing detailed operations of complex applications under diverse network conditions is invaluable for understanding the design and performance of new protocols and applications before their real deployment. We introduce a novel method that combines high-performance large-scale network simulation and high-fidelity network emulation, and thus enables real instances of network applications and protocols to run in real operating environments and be tested under simulated network settings. Using our approach, network simulation and emulation can form a symbiotic relationship, through which they are synchronized for an accurate representation of the network-scale traffic behavior. We introduce a model downscaling method along with an efficient queuing model and a traffic reproduction technique, which can significantly reduce the synchronization overhead and improve accuracy. We validate our approach with extensive experiments via simulation and with a real-system implementation. We also present a case study using our approach to evaluate a multipath data transport protocol. |

| | 2967 | <br><br><b>Abstract: </b>Network virtualization enables programmability to the substrate network provider who provisions and manages virtual networks (VNs) for service providers. A mix of software-defined and autonomic technology improves the flexibility of network management, including dynamic reconfiguration in the virtualized networking environment (VNE). Virtual router (VR)s run at a logical level where software failures may be more frequent. Thus, a VR failure is more frequent than a physical router failure on the substrate network. In this paper, we present a software-defined resilient virtualized networking environment where a VN topology can be restored by using a preserved standby virtual router (S-VR) after a VR failure. We illustrate a preliminary autonomic setup of a VNE on the GENI testbed. |

| | 2993 | <br><br><b>Abstract: </b>In this paper we report the results of a qualitative research study of the GENI cyberinfrastructure: a program of four federated cyberinfrastructures. Drawing on theories of stakeholder positioning, we examine how different GENI stakeholders attempt to enlist new participants in the cyberinfrastructures of GENI, and leverage existing relationships to create sustainable infrastructure. This study contributes to our understanding of how cyberinfrastructures emerge over time through processes of stakeholder alignment, enrollment, and through synergies among stakeholder groups. We explore these issues to better understand how cyberinfrastructures can be designed to sustain over time. |

| | 3019 | <br><br><b>Abstract: </b>Experimentation is an invaluable part of learning in all sciences. However, building and maintaining laboratories is expensive, time and space consuming. Moreover, in computer science advances in technology can quickly make the infrastructure obsolete. In this paper we advocate the use of recently deployed public testbeds as remote labs for computer science education. As an example we describe the successful use of the GENI testbed in graduate and undergraduate courses and present a specific case study of GENI being used in an undergraduate class on Network Management and Intelligent Networks. |

| | 3032 | <br><br><b>Abstract: </b>An architecture called the slice-exchange-point (SEP) has been designed for federating heterogeneous net-work-virtualization platforms by creating and managing slices (virtual networks). SEP enables whole inter-domain resources to be managed by the network manager of any single domain. Slice-operation commands are propagated to other domains through SEP by using a common API. SEP introduces the following four features: infrastructure neutrality, single interface federation, abstract and clean federation, and extensibility of capabilities. SEP's functions to achieve these features are discussed. SEP was partially implemented on two VNode domains and one ProtoGENI domain and was verified to function effectively. |
