Traditionally, the design and implementation of network based applications, especially large-scale, high performance applications, have had to be compromised across multiple dimensions interfaces, services, performance, flexibility, protocols, architecture, technology, etc. These restrictions exist, in part, because the most widely deployed communications(More)
In this paper, we describe InstaGENI, a distributed cloud based on programmable networks designed for the GENI Mesoscale deployment and large-scale distributed research projects. The InstaGENI architecture closely integrates a lightweight cluster design with softwaredefined networking, Hardware-as-a-Service and Containers-as-a-Service, remote monitoring and(More)
Next generation clouds, based on highly programmable, high performance networks, especially those supported by Software-Defined-Networking (SDN) have attracted significant interest by research communities. In recognition of the increasing importance of advancing cloud services and technologies, especially for providing Internet services, the US National(More)
Data sets in e-science are increasing exponentially in size. To transfer these huge data sets we need to make efficient use of all available network capacity. This means using multiple paths when available. In this paper a prototype of such a multipath network is presented. Several emerging network technologies are integrated to achieve the goal of(More)
In part because of the limitations of the TCP/IPprotocols used by the current Internet, the Future Internet has become an attractive network research topic. Recently, several projects focused on the Future Internet have been launched around the globe based on the Open Flow platform, such as those that are part of the GENI project in the U.S., the OFELIA(More)
Currently, support for digital media is one of the fastest growing requirements of the Internet as demand transitions from services designed to support primarily text and images to those intended also to support rich, high quality streaming multi-media. In response to the need to address this important 21st century communications challenge, an international(More)
Large scale data intensive science requires global collaboration and sophisticated high capacity data management. Traditionally, mismatches between the requirements of large scale science and the restrictions of generally deployed networks have been problematic. However, the emergence of more flexible networking, for example, using techniques based on(More)
Because communication services are global, to advance the state of the art for communication services along with underlying architecture, technologies, and facilities, network science research communities require world-wide experimental research facilities and testbeds. Previously, designing, implementing, and operating such global research facilities have(More)
Software Defined Networks (SDNs), primarily based on OpenFlow, are being deployed in single domain networks around the world. The popularity of SDNs has given rise to multiple considerations about designing, implementing, and operating Software-Defined Network Exchanges (SDXs), to enable SDNs to interconnect SDN islands and to extend SDNs across multiple(More)
