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.” George Heilmeier, Chairman Emeritus, Bellcore 7 NINJA Computing Infrastructure Server Client Proxy Router Compute Node • 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 8 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 9 Transparent Information Access Speech-to-Text Speech-to-Voice Attached-Email Call-to-Pager/Email Notification Email-to-Speech All compositions of the above! Universal In-box Policy-based Location-based Activity-based 10 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 realtime 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 11
