Mission Statement

Lead the evolution of the Internet through fundamental protocol and systems research

– Grounded in real-world prototypes that are deployed across diverse user communities

– Unify on-going and future research projects– Facilitate technology transfer and standardization– Work closely with industrial partners in an open

laboratory environment

3

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

4

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

“From POTS to PANS: Telecommunications in

Transition”“Today, the telecommunications sector is beginning

to reshape itself, from a vertically to a horizontally structured industry. … [I]t used to be that new capabilities were driven primarily by the carriers. Now, they are beginning to be driven by the users. … There’s a universe of people out there who have a much better idea than we do of what key applications are, so why not give those folks the opportunity to realize them. … The smarts have to be buried in the ‘middleware’ of the network, but that is going to change as more-capable user equipment is distributed throughout the network. When it does, the economics of this industry may also change.”

NINJA Computing Infrastructure

• Computing resources inside the routing topology, not just at the leaves

• Paths chosen for location of operators as much as for shortest # of hops

• Mobile code that specializes the services provided by servers

• Mobility, management of bottleneck links, “integration” services, service handoff

ICEBERG• 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

Summary and Conclusions

• Internet-Scale Systems Research Group: Emerging Network-centric Distributed Architecture spanning processing and access

• Open, composable services architecture--the wide-area “operating system” of the 21st Century

• Beyond the desktop PC: information appliances supported by infrastructure services--multicast real-time media plus proxies for any-to-any format translation and delivery to diverse devices

• Common network core: optimized for data, based on IP, enabling packetized voice, supporting user, terminal, and service mobility
