What and Who
Title:Towards Latency Guarantees in Datacenters
Speaker:Keon Jang
coming from:Google
Speakers Bio:Keon Jang is a Software Engineer at Google Networking Infrastructure team. Previously he was a research

scientist at Intel, and before that he was a postdoctoral researcher at Microsoft Research Cambridge where
he worked with Hitesh Ballani. Keon got his PhD from KAIST in Daejon, South Korea where he was advised
by Sue Moon and KyoungSoo Park. His current research focuses on datacenter networks.

A large portion of computation is now carried out in datacenter. A single datacenter hosts several
100s or 1000s of applications which share common compute and network resources in a datacenter.
Isolating each application's performance, i.e., ensuring that its performance is predictable regardless
of the behavior of other applications is essential to developing and deploying data center applications,
since otherwise developers need to account for co-located applications, which increases development
and deployment complexity. Despite its importance current approaches to performance isolation are
incomplete, and focus mostly on isolating computational resources. In this talk I present two schemes
for isolation network performance. The first, Silo, takes a resource allocation based approach and
implements mechanisms for guaranteeing an application's network latency and throughput. The second,
Express Pass, takes a congestion control based approach and fairly partitions network resources across
applications.  Both approaches require no hardware (ASIC) changes, and can be deployed in today's
datacenter. This shows that full application performance isolation is achievable today.
