Strategy
• Leverage interdisciplinary systems expertise
in network-based applications, scalable
services, network-connected computing
platforms
• Work collaboratively across applications, OS,
networks, architecture
• Interact closely with industry, to obtain early
access to leading edge technologies and
facilitate tech transfer
• Cultivate ties with Bay Area (and beyond!)
networking and systems research community

Internet-Scale Systems
• Extremely large, complex, distributed,
heterogeneous, with continuous and rapid
introduction of new technologies
• Feasible architectures

Millennium Project Goals
• Enable major advances in Computational
Science and Engineering
– Simulation, Modeling, and Information Processing becoming
ubiquitous
• Explore novel design techniques for large,
complex systems
– Fundamental Computer Science problems ahead are
problems of scale
• Develop fundamentally better ways of
assimilating and interacting with large volumes
of information
– and with each other
• Explore emerging technologies
– networking, OS, devices
9
Ninja Project Goals
• Create a framework that enables programmatic
generation and composition of services from
strongly typed reusable components
• Key Elements
– Structured architecture with a careful partitioning of state
» Bases, Active Routers, and Units
– Wide-area paths formed out of strongly-typed components
» Operators and Connectors
– Execution environments with efficient, but powerful
communication primitives
» Active Messages + capsules
» TACC + persistence + customization
10
ICEBERG Project Goals
• Demonstrate ease of new service deployment
– Packet voice for computer-telephony integration
– Speech- and location-enabled applications
– Complete interoperation of speech, text, fax/image across the
four P’s: PDAs, pads, pagers, phones)
– Mobility and generalized routing redirection
• Demonstrate new system architecture to support
innovative applications
– Personal Information Management
» Universal In-box: e-mail, news, fax, voice mail
» Notification redirection: e.g., e-mail, pager
– Home networking and control of “smart” spaces,
sensor/actuator integration
» Build on experience with A/V equipped rooms in Soda Hall
