Workshop Speakers u Rutgers, Computer Science n Disco Lab n Power and Energy Management Lab (EEL) u University of Helsinki, Computer Science u Rutgers. , WINLAB/ Electrical and Computer Engineering u New Jersey Institute of Technology u Siemens Corporate Research, Inc. u University of Tromso, Norway

Distributed Computing Laboratory u Created in 1998 u One faculty, ten graduate students u Five active projects u Three active NSF grants ($2. 1 Million) u Three industrial collaborations n Network Appliance, Inc n Siemens Corporate Research, Inc n VMware, Inc u International Collaboration n INRIA/IRISA Rennes, UPC Barcelona, University Paris 6, University of Helsinki, Technical University of Bucharest n Three joint workshops: Rennes (Dec 2005), Rutgers (May 2006), Paris (June 2006) n Six foreign graduate students visited Disco Lab in 2006! u Graduate/Light Seminars: Network-Centric Systems, Self-Healing, Vehicular Computing and Networking, Intrusion Detection

Network-Centric Systems u Promising border-crossing systems research area u Networking has moved from periphery to center n Dictates performance n Limits availability n Makes programmability difficult n Opens software vulnerabilities to attacks u Networking has become the main challenge/obstacle/opportunity for systems research u Wide range of network-centric systems, from network servers to pervasive systems

Disco Lab Project Areas u Server Networking Performance u Service Availability u Remote Healing u Defensive Architectures u Distributed Embedded Systems u Pervasive Computing using Smart Phones u Vehicular Computing Systems

Server Networking Performance u Execution of traditional TCP/IP protocol stack dominates the server overhead u Two approaches to reduce transport protocol impact on server performance: offload or make it lighter u Offloading TCP: TCP Servers u Lightweight transport (Remote DMA): Memory. Mapped User-Level NFS over RDMA n Collaboration with Network Appliance, Inc

Service Availability u For the client, server availability is not enough u How to provide end-to-end service availability? u Migratory TCP n Migrate server end-point of live connection u Service Continuations n Migrate service sessions between cooperative servers running the same service

Remote Healing u Traditionally, recovery from OS failures means reboot u How to access memory when OS is unavailable? u Backdoor n Trusted I/O device that can execute remote memory operations without involving local OS/CPU n I-NIC (e. g. Myrinet) supporting R-DMA operations u Remote Monitoring n Sensor Box u Remote Repairing n Repare remote OS state u Remote Recovery n Recover service sessions from a failed OS

Defensive Architectures u From OS failures to compromised OS n Once OS is compromised, the attack is hard to detect and even harder to contain n How to do intrusion detection+containment automatically? u Defensive Architectures use trusted entities to monitor system integrity and/or enforce access policies n A priviledged VM: Paladine n A TPM-based service code monitor: Satem n Interposed between client and file server: File. Wall u Continuous Monitoring n Discrete detection remains vulnerable n Continuous invariant checking u Cooperative Monitoring n Cooperative detection u Cooperative Continuous Monitoring n Continuous checking of distributed invariants

Distributed Embedded Systems u We know how to program distributed systems with stable configuration and reliable networking u We do not know how to program large and dynamic networks of embedded systems u Execution migration and self-routing n Smart Messages u High-level distributed models for programming embedded systems in the physical space n Spatial Programming n Spatial Views (EEL in collaboration with Disco Lab)

Pervasive Computing using Smart Phones u Smart phone n the first device that enables pervasive computing and makes undergraduate students happy u Smiles project n Exploit dual connectivity for service provisioning n Indoor localization using camera phones (Demo!) n Privacy guarantees in location-based services u Next generation: Smart phone + i. Pod n Low-bandwidth continuous connectivity is a form of weak connectivity n Coda on smart phones?

Vehicular Computing Systems u Make mobile ad-hoc networks real and real-time! u Dedicated Short Range Communications (DSRC) for V 2 V communication u What are the killer applications? n Near view for active accident avoidance: Traffic. View n Far-view for automobile congestion detection/avoidance and route planning u Traffic. View: one of the first outdoor experiments with a real vehicular computing system (Demo!) u Security concerns: Trust and Privacy n Probabilistic validation of aggregated traffic data u Content-distribution over vehicular networks u Dual connectivity: cellular/short range

Some Lessons u Novel hardware inspires systems research n RDMA, TPM, Smart Phones, DSRC u Offloading as principle of systems design n Functionality, monitoring, policy enforcement, validation u Pervasive computing and vehicular computing are coming n Outdoors is not like indoors! n Outdoor systems are hard to build, test and evaluate u International collaboration is a professional and social exercise absolutely necessary for students
