Análise e comparação de técnicas e aceleradores de processamento de pacotes

Abstract

The major advances in network interfaces of servers were not accom- panied by the network stack of traditional operating systems. While Network Interface Cards (NICs) are able to achieve up to 100 Gbit/s of traffic, operating systems can achieve only 1/10 of this performance. Due to this, techniques for faster packet processing are being developed in order to reduce performance loss. This paper presents some of these techniques and frameworks where these are implemented, and shows a performance comparison of those frameworks against traditional operating systems, to justify their usage.
