SUMMARY: On the Art of Wielding a Double-Edged Sword (or\, Finessing Moder
 n Networks) - Samer Al-Kiswany\, University of Waterloo

DESCRIPTION:Abstract\nRecent advances in networking technology have signif
 icantly increased network configurability\, programmability\, and flexibil
 ity. These advances have introduced programmability to all network compone
 nts—from programmable switches and network cards to the deployment of co
 nfigurable software switches on all nodes in an infrastructure.\n \nThis i
 ncrease in network “softwarization” is a double-edged sword. On the on
 e hand\, network programmability facilitates the building of line-rate app
 lication-specific packet processing logic. This in turn enables building i
 n-network system-specific optimizations\, such as optimized distributed qu
 ery processing\, scheduling\, and load balancing. In this talk\, I will pr
 esent FlairKV (NSDI ‘20)\, a key-value storage system that leverages pro
 grammable switches to significantly accelerate read operations.\n \nOn the
  other hand\, increased network softwarization (perhaps not surprisingly) 
 contributes to an increase in the frequency and complexity of network fail
 ures. Can modern systems tolerate these faults\, and can we build a generi
 c fault tolerance technique for them? In this talk\, I will present NEAT (
 OSDI ‘18)\, a comprehensive study of the impact of network partitioning 
 failures on modern systems. Moreover\, we recently identified a peculiar t
 ype of network fault called partial partitioning. I will present NIFTY (OS
 DI ‘20)\, a generic fault tolerance technique for partial partitions.\n 
 \nBio:\nSamer Al-Kiswany is an assistant professor at David Cheriton Schoo
 l of Computer Science at the University of Waterloo\, Canada. His research
  interest is in distributed systems\, networking\, and data management and
  processing engines. In particular\, his work focuses on reconsidering sys
 tems design in light of recent changes in cloud applications and platforms
 . Samer received his PhD from the University of British Columbia in 2013. 
 After his PhD\, he joined the University of Wisconsin–Madison as a postd
 octoral fellow. Dr. Al-Kiswany is the recipient of ten national and intern
 ational awards\, including the Killam Doctoral Fellowship\, the NSERC Post
 doctoral Fellowship\, and the IEEE George Michael HPC Fellowship.
