“…GIMI builds on OMF and its associated measurement library, OML [12], which are already used on GENI WiMAX testbeds. The GIMI toolset adds utilities for pushing measurements from a WiMAX testbed to a user's personal storage on an iRODS [13] data grid, and for visualization and presentation of measurement results.…”

Abstract-In the last few years, there has been an increasing awareness of the need to evaluate new mobile applications and protocols in realistic wireless settings, and platforms such as the GENI WiMAX testbeds have been developed to fulfill this need. However, wireless testbed users have experienced frustration when straightforward usage scenarios do not consistently agree with the high data rates that are advertised by the wireless technology. This work seeks to clarify the performance characteristics of two GENI WiMAX testbeds under various wireless signal conditions and network traffic patterns. By measuring the performance of several popular wireless Internet applications in two very different wireless environments, we gain a deeper understanding of how a researcher may expect the GENI WiMAX platform to behave. Our findings include some counterintuitive results, e.g. that increasing signal quality can reduce application throughput, and that applications using a single TCP flow may achieve as much as 72% less throughput than an application in an identical setting that uses multiple TCP flows. With this work, we hope to help other researchers design realistic experiments on wireless Internet systems, understand the perceived shortcomings of the GENI WiMAX platform, and interpret their experimental results in the context of the wireless setting in which the experiment was conducted.

“…It operates in licensed frequency centered at 2.595 GHz. The testbed platform also includes the suite of instrumentation and measurement utilities that make up the OML measurement framework [12]. We used OML, and the OML4Py Python module [6] in particular, to instrument the CoopShim software with measurement "hooks" that stream measurement data to a database at regular intervals while the application is running.…”

In this work, we consider the challenge of delivering high-quality multimedia content to users concentrated in a small physical location, e.g., a sports stadium in which fans may view extra video content on their mobile devices. Because each user experiences a different wireless channel condition, it is difficult to deliver this content efficiently to all users. A hybrid network architecture has been proposed that uses a peer to peer exchange of packets over an assistant network to supplement the primary infrastructure network in this scenario. We describe an implementation of this popular technique which may be used in a variety of network environments and applications. In trials on a wireless networking testbed, using WiMAX as the primary network and WiFi as an assistant network, we find that our implementation can recover up to 92% of packets lost over the primary network.

While more and more services become virtualized and always accessible in our society, laboratories supporting computer science (CS) lectures have mainly remained offline and class-based. This apparent abnormality is due to several limiting factors, discussed in the literature, such as the high cost of deploying and maintaining computer network testbeds and the lack of standardization for the presentation of eLearning platforms. In this paper, we present the FORGE toolkit, which leverages experimentation facilities currently deployed in international initiatives for the development of e-learning materials. Thus, we solve the institutional challenge mentioned in the ACM/IEEE 2013 CS curricula concerning the access and maintenance of specialized and heterogeneous hardware thanks to a seamless integration with the networking test-bed community. Moreover, this project builds an ecosystem, where teaching and educational materials, tools, and experiments are available under open scheme and policies. We demonstrate how it already meets most of the requirements from the network and communication component of CS 2013 and some of the labs of the Cisco academy. Finally, we present experience reports illustrating the potential benefits of this framework based on the first deployments in four post-graduate courses in prestigious institutions around the world.INDEX TERMS eLearning, networking, testbeds.
