DESCRIPTION:Title: From the Cloud to SoNIC: Precise Realtime Software
	 Access and Control of Wired Networks\nSpeaker: Hakim
	 Weatherspoon\nAbstract: We are\, at last\, on the verge of realizing the
	 computer utility vision (Multics: 1965). Its name today is cloud
	 computing. It promises to catalyze the technology economy\,
	 revolutionize health care\, military\,  government\, and financial
	 systems\, scientific research\, and of course society. Central to the
	 cloud and all of its promise is the network. Unfortunately\, much of the
	 network protocol stack is a black box to systems programmers\,
	 especially the physical and data link layers. These two layers contain
	 valuable information to help ensure the network is reliable and
	 performing. The issue: These two layers are often inaccessible in
	 software as a result much of there potential goes untapped. In this
	 talk\, I will introduce SoNIC\, Software-defined Network Interface
	 Card\, which provides access to the physical and data link layers in
	 software. By implementing the creation of the bitstream in software and
	 the transmission of the bitstream in hardware\, SoNIC provides complete
	 control over the entire network stack in realtime. As an example of
	 SoNIC’s fine-granularity control\, it can perform precise network
	 measurements (in realtime) at the pico-second scale\, accurately
	 characterizing network components such as routers\, switches\, and
	 network interface cards. Further\, SoNIC enables timing channels with
	 nano-second modulations that are undetectable in software. \n \nBIO:
	 Hakim Weatherspoon is an assistant professor in the Department of
	 Computer Science at Cornell University. His research interests cover
	 various aspects of fault-tolerance\, reliability\, security\, and
	 performance of large Internet-scale systems such as cloud computing and
	 distributed systems. Professor Weatherspoon received his Ph.D. from
	 Berkeley in 1999. Before receiving his PhD\, Prof. Weatherspoon received
	 his B.S. from University of Washington. Prof. Weatherspoon is an Alfred
	 P. Sloan Fellow\, Kavli Frontiers Fellow from the National Academy of
	 the Sciences\, and recipient of an NSF CAREER award\, DARPA Computer
	 Science Study Panel (CSSP)\, IBM Faculty Award\, the NetApp Faculty
	 Fellowship\, Intel Early Career Faculty Honor\, and the Future Internet
	 Architecture award from the National Science Foundation (NSF).
