 Graduate/Light Seminars: Network-Centric Systems, Self-Healing,
Vehicular Computing and Networking, Intrusion Detection
Network-Centric Systems
 Promising border-crossing systems research area
 Networking has moved from periphery to center
 Dictates performance
 Limits availability
 Makes programmability difficult
 Opens software vulnerabilities to attacks
 Networking has become the main
challenge/obstacle/opportunity for systems research
 Wide range of network-centric systems, from network
servers to pervasive systems
Disco Lab Project Areas
 Server Networking Performance
 Service Availability
 Remote Healing
 Defensive Architectures
 Distributed Embedded Systems
 Pervasive Computing using Smart Phones
 Vehicular Computing Systems
Server Networking Performance
 Execution of traditional TCP/IP protocol stack
dominates the server overhead
 Two approaches to reduce transport protocol impact
on server performance: offload or make it lighter
 Offloading TCP: TCP Servers
 Lightweight transport (Remote DMA): MemoryMapped User-Level NFS over RDMA
 Collaboration with Network Appliance, Inc
Service Availability
 For the client, server availability is not enough
 How to provide end-to-end service availability?
 Migratory TCP
 Migrate server end-point of live connection
 Service Continuations
 Migrate service sessions between cooperative servers
running the same service
Remote Healing
 Traditionally, recovery from OS failures means
reboot
 How to access memory when OS is unavailable?
 Backdoor
 Trusted I/O device that can execute remote memory
operations without involving local OS/CPU
 I-NIC (e.g. Myrinet) supporting R-DMA operations
 Remote Monitoring
 Sensor Box
 Remote Repairing
 Repare remote OS state
 Remote Recovery
 Recover service sessions from a failed OS
Defensive Architectures
 From OS failures to compromised OS
 Once OS is compromised, the attack is hard to detect and even
harder to contain
 How to do intrusion detection+containment automatically?
 Defensive Architectures use trusted entities to monitor system
integrity and/or enforce access policies
 A priviledged VM: Paladine
 A TPM-based service code monitor: Satem
 Interposed between client and file server: FileWall
 Continuous Monitoring
 Discrete detection remains vulnerable
 Continuous invariant checking
 Cooperative Monitoring
 Cooperative detection
 Cooperative Continuous Monitoring
 Continuous checking of distributed invariants
Distributed Embedded Systems
 We know how to program distributed systems with
stable configuration and reliable networking
 We do not know how to program large and dynamic
networks of embedded systems
 Execution migration and self-routing
 Smart Messages
 High-level distributed models for programming
embedded systems in the physical space
 Spatial Programming
 Spatial Views (EEL in collaboration with Disco Lab)
Pervasive Computing using Smart
Phones
 Smart phone
 the first device that enables pervasive computing and
makes undergraduate students happy
 Smiles project
 Exploit dual connectivity for service provisioning
 Indoor localization using camera phones (Demo!)
 Privacy guarantees in location-based services
 Next generation: Smart phone + iPod
 Low-bandwidth continuous connectivity is a form of
weak connectivity
 Coda on smart phones?
Vehicular Computing Systems
 Make mobile ad-hoc networks real and real-time!
 Dedicated Short Range Communications (DSRC) for V2V
communication
 What are the killer applications?
 Near view for active accident avoidance: TrafficView
 Far-view for automobile congestion detection/avoidance and
route planning
 TrafficView: one of the first outdoor experiments with a real
vehicular computing system (Demo!)
 Security concerns: Trust and Privacy

Probabilistic validation of aggregated traffic data
 Content-distribution over vehicular networks
 Dual connectivity: cellular/short range
Some Lessons
 Novel hardware inspires systems research
 RDMA, TPM, Smart Phones, DSRC
 Offloading as principle of systems design
 Functionality, monitoring, policy enforcement, validation
 Pervasive computing and vehicular computing are
coming
 Outdoors is not like indoors!
 Outdoor systems are hard to build, test and evaluate
 International collaboration is a professional and
social exercise absolutely necessary for students
