Integration of OMF-Based Testbeds in a Global-Scale Networking Facility

Abstract. PlanetLab is a global scale platform for experimentation of new networking applications in a real environment. It consists of several nodes, offered by academic institutions or companies spread all over the world, that can be shared by the networking community for its tests. The main drawback of PlanetLab is its scarce heterogeneity in terms of the access technologies it offers. In this paper we discuss the efforts we made in order to alleviate this problem. We first developed a tool that allowed us to integrate a WiFi testbed controllable by OMF (Orbit Management Framework) [16] in PlanetLab by means of a multi-homed PlanetLab node. OMF is a set of tools that make it easy to automatically execute experiments and collect measurements on a WiFi testbed. The tool we developed allows, more generally, to solve the issues that arises with multi-homed PlanetLab nodes (i.e. PlanetLab nodes having more than a network interface). In order to be able to fully exploit the potential of such PlanetLab nodes, there is the need for the users to add routin

The GpENI Testbed: Network Infrastructure, Implementation Experience, and Experimentation

The Great Plains Environment for Network Innovation (GpENI) is an international programmable network testbed centered initially in the Midwest US with the goal to provide programmability across the entire protocol stack. In this paper, we present the overall GpENI framework and our implementation experience for the programmable routing environment and the dynamic circuit network (DCN). GpENI is built to provide a collaborative research infrastructure enabling the research community to conduct experiments in Future Internet architecture. We present illustrative examples of our experimentation in the GpENI platform

Challenges for cloud networking security

Cloud computing is widely considered as an attractive service model since the users commitments for investment and operations are minimised, and costs are in direct relation to usage and demand. However, when networking aspects for distributed clouds are considered, there is little support and the effort is often underestimated. The project SAIL is addressing cloud networking as the combination of management for cloud computing and vital networking capabilities between distributed cloud resources involved to improve the management of both. This position paper presents new security challenges as considered in SAIL for ensuring legitimate usage of cloud networking resources and for preventing misuse
