Large-scale testbeds like G-Lab or PlanetLab provide realistic environments for real-world evaluation of distributed applications. They offer means for realistic testing and validation that are hard to achieve using simulations. In contrast to simulated environments, real-world testbeds require a

Abstract. The management of resources on testbeds, including their description, reservation and verification, is a challenging issue, especially on of large scale testbeds such as those used for research on High Per-formance Computing or Clouds. In this paper, we present the solution designed

deployments do not exist, the current techniques proposed for service composition are difficult to test and compare. In this paper we propose a synthetic testbed that can be used for simulating large deployments of services and also for generating service composition problems. The testbed could prove

We have built an Ad hoc Protocol Evaluation testbed (APE) in order to perform large-scale, reproducible experiments. APE aims at assessing several different routing protocols in a real world environment instead of by simulation. We present the APE testbed architecture and report on initial

on the other hand, vendors do not need to expose the internal workings of their switches. In addition to allowing researchers to evaluate their ideas in real-world traffic settings, OpenFlow could serve as a useful campus component in proposed large-scale testbeds like GENI. Two buildings at Stanford

the applicability and benefits of the testbed in evaluating technology pilots and prototyping new ubiquitous services in real-world urban setting. We conclude with a discussion on the challenges in deploying this kind of a large-scale testbed in a public urban space.

This work is supported by the ANR TLCOM project SensLAB. Abstract—SensLAB’s goal is to provide a very large scale open wireless sensor network testbed, by deploying 1024 nodes over 4 interconnected sites, and to offer a reference tool for the wireless sensor network community. Our demonstration

Multipath TCP is an experimental transport protocol with remarkable recent past and non-negligible future potential. However, the lack of available large-scale testbeds and pub-licly accessible multiple paths grossly prohibits the adoption of the technology. Here, we demonstrate a large-scale multi
