Quand<\/strong>: le 22 mai 20188 \u00e0 11h Title:<\/strong> Software acceleration techniques for high-speed routers: an introduction and a use case (Vector Packet Processor)<\/p>\n Abstract:<\/strong> Nowadays’ software routers typically offers in user-space networking, often coupled with the flexibility of a modular router, thus being perfectly suited to implement Network Function Virtualization (NFV) on commodity hardware.<\/p>\n The state-of-the-art tools highly rely on the benefits brought by acceleration techniques such as batch processing and other similar techniques that have become commonplace in high-speed networking stacks (such as netmap or DPDK). At the same time, several code optimizations can be integrated to greatly improve the achievable processing throughput.<\/p>\n In this seminar we introduce the most common software acceleration techniques used to provide line-rate processing capabilities on commodity hardware at very high-speed (i.e.10 Gbps on a single CPU core). We conclude this talk by listing on-going activities in the domain of high-speed software networking.<\/p>\n Titre :<\/strong> \u00ab\u00a0Techniques d’acc\u00e9l\u00e9ration logicielle pour le d\u00e9veloppement des routeurs logiciels \u00e0 haut-d\u00e9bit : introduction et un cas d’usage (Vector Packet Processor)\u00a0\u00bb<\/p>\n R\u00e9sum\u00e9 :<\/strong> Ce type de logiciels, appel\u00e9s \u00ab software routers \u00bb offrent la possibilit\u00e9 de r\u00e9aliser des nombreux types d\u2019applications r\u00e9seaux, et sont sp\u00e9cialement adapt\u00e9s pour la conception et le d\u00e9veloppement des fonctionnalit\u00e9s de virtualisation (par exemple dans le domaine de la \u00ab Network Function Virtualization \u00bb (NFV).<\/p>\n Les software routers \u00e0 l\u2019\u00e9tat de l\u2019art utilisent plusieurs techniques d\u2019acc\u00e9l\u00e9ration au niveau logiciel et au niveau de la carte r\u00e9seau, typiquement \u00e0 travers des techniques de codage sp\u00e9ciales ou des drivers et des biblioth\u00e8ques optimis\u00e9es (comme netmap ou Intel DPDK).<\/p>\n Dans ce s\u00e9minaire nous allons pr\u00e9senter les techniques d\u2019acc\u00e9l\u00e9ration logicielles utilis\u00e9es pour la r\u00e9alisation et mise en place des routeurs logiciels qui peuvent \u00eatre utilis\u00e9s dans le domaine du tr\u00e8s haut d\u00e9bit (par exemple plusieurs dizaines des Giga octets par seconde tout en utilisant un seul processeur).

\nIn the last decade, a number of software frameworks started to appear that implement, directly in user-space with kernel-bypass mode, high-speed software data plane functions on commodity hardware.<\/p>\n
\nWe then focus on a particular use case, namely Vector Packet Processor (VPP), that is one of such frameworks (recently open-sourced under the Linux Foundation project fd.io) representing an interesting point in the design space in that it implements most of the known acceleration techniques. We describe VPP’s architecture, our experimental methodology, and our extensive performance evaluation campaign on a real testbed (measuring typical variables such as throughput or latency).<\/p>\n
