Speaker: Luigi Rizzo, from Universita` di Pisa Title: Building efficient network dataplanes in software Date/time: 12pm lunch and 12:30-1:30pm talk, Tuesday September 1 Location: CS 402 Abstract: In this talk we give a survey of solutions -- and especially, discuss the underlying design principles -- that we developed in recent years to achieve extremely high packet processing rates in commodity operating systems, for both bare metal and virtual machines. By using simple abstractions, and resisting the temptation to design systems around performant but constraining assumptions, we have been able to build a very flexible framework that addresses the speed and latency communication requirements of both bare metal and virtual machines up to the 100 Gbit/s range. Our goal is not to provide the fastest framework in the universe, but one that is easy to use and rich of features (and still, amazingly fast), to taking away concerns on the dataplane's speed from (reasonable) network applications. Our NETMAP framework, opensource and BSD licensed, runs on 3 OSes (FreeBSD, Linux, Windows); provides access to NICs, host stack, virtual switches and point-to-point channels (netmap pipes), running between 20 and over 100Mpps on software ports, and saturating NICs with just a single core (reported up to 45 Mpps on recent 40G nics); achieves bare-metal speed on VMs thanks to a virtual passthrough mode (available for Qemu and bhyve); and can be used with no modifications by libpcap clients. Bio: Luigi Rizzo is an associate professor at the Universita` di Pisa. He has worked on network emulation, high performance networking, packet scheduling, multicast and reliable multicast. He is a long time contributor to FreeBSD, for which he has developed several subsystems including the dummynet network emulator, the ipfw firewall, and the netmap framework. He has been program committe member for for sigcomm, conext, infocom, nsdi, Usenix ATC, ANCS and other conferences, as well as PC chair for Sigcomm 2009 and Conext 2014, ANCS 2016, and general chair for Sigcomm 2006. Luigi has been a frequent visiting researcher at various institutions including ICSI/UC Berkeley, Google Mountain View, Intel Research Cambridge, Intel Research Berkeley.

Siemens talks next week: 12-1:30pm Tue Aug 25 on cybersecurity, 12-1:30pm Thu Aug 27 on engineering complex systems
by Jennifer Rexford 22 Aug '15

22 Aug '15

Two talks this coming week from Siemens in Princeton Siemens Corporation Summer Lunch & Learn Series Tuesday, August 25, Noon-1:30 PM EQuad, Room J223 Cyber Security and its impact on Siemens & Corporate Technology Lunch will be provided Benjamin Collar, Head of Research Group – Cyber Security Americas is a dynamic engineering executive who excels in developing teams and individuals. As head of cyber-security research at Siemens Corporate Technology, Benjamin leads a team of security experts who execute and support the security strategy of the Siemens operating companies. He is a strong advocate for cyber-security and privacy within the company as well as in the public. Ben is constantly seeking new ways to break barriers and challenge the status quo as he creatively drives results across organizational boundaries. Thursday, August 27, Noon-1:30 PM EQuad, Room J201 Engineering Complex Systems – Fun with Large Spatial, Temporal, Fidelity, and Parameter Spaces Lunch will be provided Dr. Arquimedes Canedo is a Principal Key Expert Scientist at Siemens Corporate Technology in Princeton, NJ. Arqui is very passionate about developing technologies for multi-disciplinary and multi-scale design, engineering, and simulation of complex systems. This talk aims at motivating graduate students, from all backgrounds, to develop ideas that will help to develop the next-generation engineering tools for complex systems. He will introduce some of the problems associated with modern engineering with a few real-world examples that illustrate the need for better tools for integrating multi-disciplinary systems. He will also present some of the research efforts at Siemens Corporate Technology in the area of industrial Automation and Control. Arqui will share his own experience on working at Siemens Corporate Technology.
