Towards a Swiss National Research Infrastructure

In this position paper we describe the current status and plans for a Swiss National Research Infrastructure. Swiss academic and research institutions are very autonomous. While being loosely coupled, they do not rely on any centralized management entities. Therefore, a coordinated national research infrastructure can only be established by federating the various resources available locally at the individual institutions. The Swiss Multi-Science Computing Grid and the Swiss Academic Compute Cloud projects serve already a large number of diverse user communities. These projects also allow us to test the operational setup of such a heterogeneous federated infrastructure

EMI Security Architecture

This document describes the various architectures of the three middlewares that comprise the EMI software stack. It also outlines the common efforts in the security area that allow interoperability between these middlewares. The assessment of the EMI Security presented in this document was performed internally by members of the Security Area of the EMI project

Automation of the UNICARagil Vehicles

The German research project UNICARagil is a collaboration between eight universities and six industrial partners funded by the Federal Ministry of Education and Research. It aims to develop innovative modular architectures and methods for new agile, automated vehicle concepts. This paper summarizes the automation approach of the driverless vehicle concept and its modular realization within the four demonstration vehicles to be built by the consortium. On-board each vehicle, this comprises sensor modules for environment perception and modelling, motion planning for normal driving and safe halts, as well as the respective control algorithms and base functionalities like precise localization. A control room and cloud functionalities provide off-board support to the vehicles, which are additionally addressed in this paper

Inferring AS Relationships Beyond Counting Edges

Routing in the Internet is strongly shaped by the business relationships between administrative domains (Autonomous Systems, AS). In this paper we propose new techniques to classify these relationships. Inspired by Lixin Gao’s seminal work on valley-free paths, we explore several ways to measure the importance of an AS which go beyond the original degree-ranking. In addition we study what information can be gathered by parsing the Routing Registry databases. Furthermore we undertake a thorough analysis and experimental comparison of all the proposed approaches known to date. Not surprisingly, the various methods all reveal different views of the business relations. In fact, by using the different measures or even a combination of them, one can tune the ranking of a given AS by a wide margin

Less than Best Effort: Application Scenarios and Experimental Results

In this article we present the wo rk done to study the potential benefits to end users and network operators and the feasibility of deploying a Less than Best Effort (LBE) service on a wide area scale. LBE is a Per-Domain Behaviour based on the Differentiated Services Quality of Service architecture. We present a brief overview of the evolution of the case for LBE, through the IETF DiffServ WG and the Internet2 QBone project, and then describe some proposed scenarios for LBE deployment in European research networks and GÉANT, the research backbone providing interconnectivity to the European National Research and Educational Networks (NRENs). The experimental results presented demonstrate the viability and importance of Quality of Service to meet a large set of network providers and users ’ requirements even in presence of communication infrastructures characterized by very high-speed connection
