German-Lab Experimental Facility

Abstract

Abstract. The G-Lab project aims to investigate concepts and technologies for future networks in a practical manner. Thus G-Lab consists of two major fields of activities: research studies of future network components and the design and setup of experimental facilities. Both is controlled by the same community to ensure, that the experimental facility fits to the demand of researchers. Researchers gain access to virtualized resources or may gain exclusive access to resource if necessary. We present the current setup of the experimental facility, describing the available hardware, management of the platform, the utilization of the Planet-Lab software and the user management.

Volume is not enough: SVC-aware server allocation for peer-assisted streaming

“…The evaluation was conducted using real-world testbed measurements in the German Lab testbed [13], a countrywide research testbed with over 170 dedicated machines. The client software was run on the testbed machines and controlled by a dedicated server.…”

Scalable distributed indexing and query processing over Linked Data

“…But, due to the unusually high number of experiments running in parallel, the resources are too sparse and the whole network generally under too much load to achieve really satisfying performance. Thus, we ran a third series of experiments on G-Lab [43]. This is a recent sub-project of PlanetLab with relatively powerful machinesand significantly less load.…”

An OpenFlow-based energy-efficient data center approach

“…The demonstration testbed is hosted on the German-Lab [6] (GLab) facility in Wuerzburg, Germany. Four rack servers are used as computing nodes running OpenNebula [1] and KVM [2] as hypervisor using the Open vSwitch [4] as virtual switch.…”
