Nikolay Aleksandrov – FreeBSD-based solution for Internet traffic management
Abstract: In this presentation I would like to present information and results about the development of in-house Internet traffic management platform which can manipulate (i.e. analyze, route, shape etc.) large volumes of traffic using standard x86 server architecture. It is based on graph theory a la netgraph, but with much simpler graph objects which give rise to much more complex and custom solutions. The software was designed with speed and flexibility in mind and has single- and multi-processor versions. We will also briefly discuss a couple of case studies (e.g. ISP, distributed routing platform, interesting custom solutions etc.) and the kernel and driver modifications that were necessary in order to achieve performance near hardware limits (e.g. completely lock-free MP version).
