Dissertation Talk: System Design for Software Packet Processing
Presentation: Dissertation Talk: CS | May 9 | 1-2 p.m. | 420 Soda Hall
Sangjin Han, University of California, Berkeley
The role of software in computer networks has never been more crucial than today, with the advent of Internet-scale services and cloud computing. Many architectural aspects of software packet processing systems, however, are decades old and evolved with little modification. In this talk, I will explore the design space of software packet processing systems in the context of two domains. First, I will start by discussing the limitations of BSD Socket, which is a de-facto standard in network I/O for server applications. I will show its limitations and propose a clean-slate API, called MegaPipe, as an alternative to BSD Socket. In the second part of the talk, we switch our focus to in-network software systems, such as network switches and middleboxes. I will present Berkeley Extensible Software Switch (BESS), a modular framework for building extensible network functions. BESS introduces various novel techniques to achieve high-performance without compromising programmability.
