Cise Educational Infrastructure: Telementoring: a Novel Approach to Teaching Undergraduate Computer Scientists @ University of Pennsylvania
This award is for the acquisition of teleconferencing and multimedia technology, and for curriculum changes to expand a curriculum in Telecommunications. The University of Pennsylvania will use a new instructional delivery system, the "video wall", to develop "Telementoring" as a long distance learning technique. The video wall is already being used in research projects by members of the AURORA Gigabit Testbed which is being supported by both NSF, DARPA and a consortium of industrial research partners. Educational materials developed will be made available to other academic institutions through Internet, and results of the educational experiments will be disseminated through publications and presentations at educational and professional meetings. The University of Pennsylvania plans to use a state of the art instructional delivery system, the "video wall", to provide multimedia and teleconferencing support for undergraduate courses in telecommunications. The video wall is an experimental video conferencing terminal with two large screen projection televisions mounted side-by-side creating the illusion of one large screen. Two cameras, co-located with the screens, are arranged to produce a single blended life- size image which is combined with high-quality directional sound. The results of the curriculum and materials development will be disseminated through Internet, and publications and presentations at educational and professional meetings.//

Cise Research Infrastructure: Asymmetric Bandwidth Channels: Applications to Real-Time Computing and Robotics @ University of Pennsylvania
CDA-9703220 Bajcsy, Ruzena University of Pennsylvania Asymmetric Bandwidth Channels: Applications to Real-Time Computing and Robotics This award is for the acquisition of infrastructure to support research which is to investigate a cost-effective and broadly deployed communication model, Asymmetric Bandwidth Channels, for which few abstractions in computer science are available. Research into the application of systems characterized by low-bandwidth interactive channels between clients and server, and a high-bandwidth broadcast from server to clients will be conducted. The proposed work will develop communications abstractions that applications can effectively use for such an infrastructure, and computational models for these abstractions. Model performance will then be evaluated on a testbed of multiple semi-autonomous robotic agents. The challenging problems to be addressed in this project include: (1) selecting which path to take from server to client; (2) determining the degree of broadcast channel sharing possible in a computer communications environment; and (3) scheduling transmissions from the shared broadcast terminal. The research will also target three fundamental problems underlying coordination of robotic agents: (1) development of world models based on observations of individual agents and exploration of an unknown or a partially known environment to build a complete model; (2) task planning based on the world model while accounting for possible uncertainties and latencies; and (3) control of robotic agents based on visual and other sensory information.

Global Active Ip Networks (Gain): Support For U.S. Participation in International Fain Consortium @ University of Pennsylvania
The fundamental project hypothesis is that management and control of the Internet is the ideal application of active networks; the researchers propose a system architecture to test this. Active Networks are constructed from elements, such as packet routers, allowing programmability on a per-user or even per-packet basis. With the new software capabilities available from systems such as Caml and Java, active networks offer the promise of more rapid adaptation to changes in technology or requirements, and more rapid introduction of new services. These potential advantages come with the disadvantages of increased complexity, and its consequences for performance and security. Early prototype systems (ANTS, CANES, Smart Packets, SwitchWare and others) illustrated various points in the design space, trading off among usability, performance, and security. The prototypes demonstrated first, that such systems could be built, that applications did indeed exist, (e.g., Active Bridging and Active Reliable Multicast), and second, that they performed well enough (10-100 Mbps) to handle the throughputs of almost all current Internet access points. Thus much of the "edge" of the Internet can add active network capabilities with minimal performance impact. A more interesting possibility exists, that of using active networking technology to incrementally activate the IP Internet. The researchers believe this can be achieved, as described within the proposal, by co-locating programmable elements with IP routers capable of fast packet forwarding. The researchers have experimented with this idea on a small scale and it offers considerable promise for increasing the manageability of the Internet with its exponential increases in scale. The Global Active IP Network (GAIN) project represents the University of Pennsylvania's research program as part of a larger 10M Euro research effort (FAIN). FAIN was considered and top-ranked within the E.U. IST Programme competition. European members were funded, with the expectation that Penn would seek funding from U.S. sources. The consortium includes University College London (UK), the Jozef Stefan Institute (Slovenia), the National Technical University of Athens (Greece), the Universitat Politecnica de Catalunya (Spain), Deutsche Telekom Berkom (Germany), France Telecom/CNET (France), KPN (Netherlands), Hitachi Europe Ltd. (UK), Hitachi Ltd. (Japan), SAG ICN (Germany), ETH Zurich (Switzerland), GMD Forschungszentrum Informationstechnik (Germany), IKV++ (Germany), INTEGRASys (Spain), and U. Penn in the United States. This proposal to NSF is a request for funds to support Penn in this international consortium. Penn's focus with GAIN is applications of Active Networks to IP network resource management and security. The researchers will investigate the prevention and mitigation of sophisticated "denial of service" attacks on security. The researchers are playing a strong role in experiment definition and evaluation for FAIN. This proposal to NSF provides background on Active Networking, outlines the research goals for an active IP network, sets this work with the context of FAIN, and argues the importance of providing U.S. participation in a truly global consortium with European and Japanese collaborators. ( The FAIN proposal has been provided to NSF.)

Csr---Pdos: Liberating Personal Computing From Hardware @ Carnegie-Mellon University
The goal of this research is to remove the tight binding of user state to specific computing hardware. This tight binding arose at the birth of personal computing nearly three decades ago, and has continued unchanged since that time. It has many negative consequences: hardware upgrades are painful, disaster recovery is complex, and total cost of ownership is high. It also forces mobile computing into a paradigm of each user carrying personal hardware, rather than traveling hands-free and taking advantage of pervasive hardware.
The proposed research aims for a new vision of on-demand personal computing called "Internet Suspend/Resume (ISR)" that exploits the ubiquitous presence of the Internet. This research explores issues at the intersection of two well-established technologies: virtual machine (VM) technology and distributed file system technology. By layering a VM on a distributed file system that performs aggressive client caching, a user's entire personal computing environment (operating system, applications and user files) can be accurately and safely delivered anywhere on the Internet.
The proposed research spans operating systems, distributed systems, mobile and pervasive computing, and security and privacy. Its has three major thrusts: (a) Coping with Huge VM State, (b) Preserving Privacy of VM State, and (c) Dynamically Varying Client Thickness. The work in each thrust includes conceptual development of novel techniques and algorithms, as well as their implementation and experimental validation in the context of a prototype. This prototype will be disseminated in open source form, for use by other researchers and by industry.
