Overview
The NMS group at MIT's Computer Science
and Artificial Intelligence Laboratory conducts research in many
areas of networking: wireless networks, Internet architecture and
protocols, overlay and peer-to-peer networks, sensor networks, network
security, and networked systems. The group was formed in 1998.
Current projects
- Datacenter networks and cloud infrastructure
- Fastpass and Flowtune
- Domino: programmable router data planes
- Flexplane: whole-network emulation in software for programmability
- Mobile and sensor computing
- Glimpse: a continuous object recognition system
- Transport protocols and mechanisms
- Remy (TCP ex machina, computer-synthesized congestion control)
- Mahimahi (record-and-replay framework for web traffic)
Unfortunately, the above list might be a bit out-of-date. The NMS papers page has a more
current list of papers.
Some past projects
Internet architecture, overlay and P2P networks
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.
Wireless, mobile, and sensor networks
- CarTel: a mobile
sensor network system developing vehicular network protocols,
software, and services.
- Cricket: An
accurate indoor location system. (Now commercially available.)
- SoftPHY and its applications: using cross-layer confidence information
(SoftPHY) from the physical layer to design better higher-layer
wireless network protocols.
- 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.
- Harnessing multiple radios and access points
- FatVAP:
Aggregating AP backhaul bandwidth.
- Horde:
networking software that allows an application to stripe data from
multiple streams across a set of dissimilar wireless network channels.
- Divert: a
multi-radio, fine-grained path selection system for improving
throughput in wireless LANs.
- APware:
improving performance and robustness for multi-rate wireless LANs.
- Fusion:
Mitigating congestion in wireless sensor networks.
- BSD (Bounded
SlowDown), Span,
LEACH and
Spin:
energy-efficient protocols for wireless and sensor networks
- Spectrumware:
new algorithms for radio and wireless physical layers for
implementation on a flexible software platform. (Now commercially
available.)
- Blueware,
protocols for internetworking with Bluetooth.
