Workloads for Programmable Network Interfaces

By Patrick Crowley Marc, Marc E. Fiuczynski, Jean-loup Baer and Brian Bershad


: Network equipment vendors are increasingly incorporating a programmable microprocessor on network interfaces to meet the performance and functionality requirements of present and emerging applications in parallel with market demand. This study identifies some properties of programmable network interface (PNI) workloads and their execution characteristics on modern high-performance microprocessor architectures including aggressive superscalar, fine-grain multithreaded, and simultaneous multithreaded architectures. 1. INTRODUCTION As networks have evolved and expanded technologically, their role and importance have also increased considerably. The role of the network interface (NI), which allows a computer system to exchange messages with other systems connected to the network, has grown accordingly. To meet the functionality and performance requirements of present and emerging network applications there has been a renewed trend by vendors to use programmable microprocessors o..
