Unfortunately, the above list might be a bit out-of-date. The NMS papers page has a more current list of papers.

P2P and overlay networks

Chord: a scalable and robust distributed hash table (DHT) enabling key-value lookups.
Project IRIS: A multi-institution NSF ITR collaboration that developed the network and system infrastructure for resilient Internet services using DHTs. Our work included:
- Dynamic evolution of P2P systems: The amount of work required to maintain good connectivity depends on the "half-life" of a P2P system.
- SFR (Semantic-Free Referencing), a reference (name) resolution service for linked systems.
- DOA (Delegation-Oriented Architecture), an extension to the Internet architecture that accommodates "middleboxes" in an architecturally coherent way using a new delegation primitive.
- DQE (Distributed Quota Enforcement), a spam control system.
- Speak-up, a defense against application-level DDoS attacks.
RON (Resilient Overlay Networks): Improving availability and resilience of Internet paths using application-controlled overlay routing.
MONET: Multi-homed overlay network of web proxies to route around network failures for Web applications.

Congestion control, traffic engineering

XCP (eXplicit Congestion Control) and TeXCP: Congestion control for high bandwidth-delay product networks and responsive traffic engineering.
CM (Congestion Manager), an integrated end-to-end congestion management architecture and congestion control algorithms for the future Internet.
OxygenTV: rate adaptation and error control for MPEG-4 delivery.

Internet routing

rcc and correct Internet routing: tools to improve routing correctness and experimental studies of Internet routing and failures.
R-BGP: Improving Internet routing connectivity.
BGPSep: Constructing correct and scalable iBGP configurations.

Network measurement

DNS analysis: trace-based analysis of DNS performance and caching.
M&M tools: multiQ and mystery, passive measurement tools suitable for large scale studies of Internet path characteristics
Routing analysis: BGP measurements.

Cricket: An accurate indoor location system. (Now commercially available.)
SMART (Scalable Medical Alert and Response Technologies) and the Patient-Centric Network: networking and systems infrastructure for health-care facilities.
INS is an intentional naming system for scalable and dynamic resource discovery. Twine aims to make INS scalable to large networks using peer-to-peer lookups, built on top of Chord.
Migrate, an end-to-end architecture for Internet host mobility, support for suspend/resume operations for mobile network applications to handle disconnections, and server failover.
