Sarthak Grover will present his General Exam on Friday, January 8, 2016 in CS 302 at 2pm.
The members of his committee are Nick Feamster (Adviser), Kyle Jamieson, and Jennifer Rexford.
Everyone is invited to attend his talk, and those faculty wishing to remain for the oral exam following are welcome to do so. His abstract and reading list follow below.
With a large increase in broadband services and capacity, it has become
important to understand home network infrastructure and usage. Over the
past two years, we have studied home network usage from two perspectives:
the gateway and the ISP. In the first empirical study of home network
availability, infrastructure, and usage, we deployed routers running custom
firmware in multiple homes to collect measurements of home and Internet
connectivity, as well as how users use their home network. Our results
showed that half the home networks studied utilize less than half their
We followed up to this work by studying the relationship between traffic
demand and service tier upgrades from the perspective of ISPs. In a unique
controlled experiment, we compare two groups of Comcast subscribers from
the same city: a control group (105 Mbps) and a randomly selected treatment
group that was upgraded to 250 Mbps without their knowledge. We study how
users who are already on service plans with high downstream throughput
respond to a higher service tier (upgraded unknowingly), as compared to a
similar control group. To our surprise, subscribers with moderate traffic
demands increase their usage in response to a service-tier upgrade
relatively more than high-volume subscribers do. We speculate that even
though these users may not take advantage of the full available capacity,
the service tier increase generally improves performance, which causes them
to use the Internet more than they otherwise would have.
