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

5

Internet-Scale Systems

• Extremely large, complex, distributed, heterogeneous, with continuous and rapid introduction of new technologies

• Feasible architectures– Decentralized, scalable algorithms– Dynamically deployed agents where they are needed– Incremental processing/communications growth– Cross-layer protocol design and optimization

• Prototyping and deployment-driven

6

ISRG Research Focus

• Infrastructure Services– Scalability– Availability– Pervasive Computing– Mobility– Proxies/Transcoders/Network Agents– Active Services

• Security and E-Commerce– PKI– Computational Economy

• Novel Applications and Architectures– Universal In-Box– IVR/Room Control

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

10

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

11

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
