Packet processing (e.g. routing, switching, firewall) with commodity hardware is a cost-efficient and flexible alternative to specialized networking hardware. On commodity hardware the CPU typically becomes the bottleneck in packet processing. However, in well-known QoS mechanisms (e.g. DiffServ), the outgoing link is assumed to be the bottleneck. This limitation is unfavorable, in particular for...
Packet processing on commodity hardware is a cost-efficient and flexible alternative to specialized networking hardware. In case of Linux, the classical QoS mechanisms (e.g DiffServ) assume that the outgoing link is the bottleneck. However, on commodity hardware the CPU typically becomes the bottleneck in packet processing. Taking into account current trends in the Internet, we assume that the percentage...
High-speed network cards supporting 10 or 40GbE (Gigabit Ethernet) are available today. Software frameworks for high-speed packet reception and transmission were created to exhaust the performance of these cards. However, these frameworks are not applicable as general-purpose solution. Thus, it is necessary to revisit general purpose network IO software that was designed more than a decade ago. In...
For long time, high-speed packet processing has been reserved for specialized hardware devices since software based solutions were not able to achieve the required performance. However, off-the-shelf packet processing hardware and software improved over the last years, which is why software based solutions cope with high-speed traffic nowadays. Due to the flexibility of software there is a trend towards...
