Abstract
Recent technological advances give a good chance to reach really effective results in the field of
open Internet equipments, also called Open Routers (ORs). Some initiatives have been activated
since the last few years to investigate the OR and related issues. But despite these activities, large
interesting areas still require a deeper investigation. This work tries to give a contribution by
reporting the results of an in-depth activity of optimization and testing realized on a PC Open Router
architecture based on Linux software and COTS hardware. The main target of this paper has been
the forwarding performance evaluation of different OR Linux-based software architectures. This
analysis has been performed with both external (throughput and latencies) and internal (profiling)
measurements. In particular, for what concerns the external measurements, a set of RFC2544
compliant tests has been proposed and analyzed.
