Aseba Meets D-Bus: From the Depths of a Low-Level Event-

Francesco Mondada, Stéphane Magnenat

The robotics research community has clearly acknowledged the need of open and standard software stacks to promote reuse of code and developments. However, to date no particular project has prevailed. We suggest that one possible reason for this is that mos ...

Optimizing network performance in virtual machines

Aravind Menon

In recent years, there has been a rapid growth in the adoption of virtual machine technology in data centers and cluster environments. This trend towards server virtualization is driven by two main factors: the savings in hardware cost that can be achieved ...

Optimizing TCP Receive Performance

Willy Zwaenepoel, Aravind Menon

The performance of the networking stack in an operating system depends on the overhead incurred by two of its components: the per-byte overhead incurred in data-touching operations, and the per-packet overhead of protocol processing and other operating sys ...

Optimizing Network Virtualization in Xen

Willy Zwaenepoel, Aravind Menon

BEST PAPER AWARDIn this paper, we propose and evaluate three techniques for optimizing network performance in the Xen virtualized environment. Our techniques retain the basic Xen architecture of locating device dri ...

Unifying software and hardware of multithreaded reconfigurable applications within operating system processes

Miljan Vuletic

Novel reconfigurable System-on-Chip (SoC) devices offer combining software with application-specific hardware accelerators to speed up applications. However, by mixing user software and user hardware, principal programming abstractions and system-software ...

A Complete Network-On-Chip Emulation Framework

Giovanni De Micheli, David Atienza Alonso, Roman Hermida Correa, Nicolas Genko

Current systems-on-chip (SoC) execute applications that demand extensive parallel processing. Networks-on-chip (NoC) provide a structured way of realizing interconnections on silicon, and obviate the limitations of bus-based solutions. NoC can have regular ...

A Method for Transparent Admission Control and Request Scheduling in E-Commerce Web Sites

Willy Zwaenepoel, Sameh Mohamed Elnikety

This paper presents a method for admission control and request scheduling for multiply-tiered e-commerce Web sites, achieving both stable behavior during overload and improved response times. Our method externally observes execution costs of requests onlin ...

Tracing attacks and restoring integrity with LASCAR

Philippe Oechslin, Alexandre Aellig

We present a novel method to trace the propagation of intrusions or malicious code in networked systems. Our solution is aimed at large numbers of loosely managed workstations typical of a research environment as found in CERN. The system tags events which ...

Combining IntServ and DiffServ under Linux

Combining Integrated Services ([1], [5]) QoS mechanisms for end-to-end signaling at hosts and Differentiated Services ([2], [10]) QoS mechanisms in the network core is one proposal for overcoming the limitation of either mechanisms when applied alone ([8]) ...
