> Title: Taming Uncertainty in Distributed Systems with Help from the Network
> 
> Abstract:
> 
> This talk presents Albatross, a new service for improving the
> availability and reliability of distributed applications. Albatross
> combines old techniques with new networking primitives (namely, software
> defined networking) to quickly decide when processes are crashed or
> partitioned, thereby enabling fast recovery.  Old techniques include the
> idea that it can be better to force a problem than to live with
> uncertainty.  However, the straight-forward application of this technique
> to network problems would be insane, so Albatross leverages new network
> primitives to force network problems on a per-process basis, thereby
> limiting interference with working processes.  In a preliminary
> evaluation, we show that Albatross has sub-second detection time for
> common network failures, and that Albatross---like similar services---can
> be used to simplify recovery logic.

> Bio:
> 
> Josh Leners received his undergraduate degree from the University of
> Chicago. He is a Ph.D. candidate at The University of Texas at Austin,
> and is currently a visiting student at New York University. He is
> thrilled to be giving another practice talk to the UCL network and
> systems group, having benefited greatly from the last one. His research
> interests are in networked and distributed systems.
