Summary: Aditya Akella Research Statement, February 2009
My broad research goal is to improve the efficiency and robustness of emerging networks and networked
systems. My key research works within this general space fall into three categories:
1. A network-wide redundancy elimination service for improving effective network capacity and
network efficiency [SIGCOMM08, SIGMETRICS09]
2. New approaches for mitigating the complexity of network management, thereby making networks
more robust and less error-prone [NSDI09, Infocom07, Mobicom08-Poster]
3. Measurement-driven approaches to ensuring robust operation of networked systems under
unexpected conditions such as large-scale attacks [USENIX08, INM07]
I try to ensure that my work is backed by sound theory and modeling. I rely mostly on simple tools from
optimization, game theory, and graph theory. I also strive to convert ideas into real deployable systems and
services. All my work involves several months of implementation followed by thorough testing in live
networks and interaction with network operators.
Redundancy Elimination as a Network Service:
Different users on the Internet often access the same content, resulting in the same data being transferred
repeatedly. Several redundancy elimination (RE) systems have explored how to suppress this redundant
content and improve network efficiency. Examples include Web caches, content distribution networks,
multicast routing protocols, P2P caches, peer-assisted transport systems (e.g. Bittorrent), and application-
independent "WAN Optimizers" that can remove redundant strings from any traffic flow. A common
constraint imposed by these systems is that they apply in a localized fashion to a specific system, protocol
