Disconnected Operation in the Coda File System
- ACM Transactions on Computer Systems
, 1992
"... Disconnected operation is a mode of operation that enables a client to continue accessing critical data during temporary failures of a shared data repository. An important, though not exclusive, application of disconnected operation is in supporting portable computers. In this paper, we show that di ..."

Disconnected operation is a mode of operation that enables a client to continue accessing critical data during temporary failures of a shared data repository. An important, though not exclusive, application of disconnected operation is in supporting portable computers. In this paper, we show
Optimistic replication
- ACM COMPUTING SURVEYS
, 2005
"... Data replication is a key technology in distributed data sharing systems, enabling higher availability and performance. This paper surveys optimistic replication algorithms that allow replica contents to diverge in the short term, in order to support concurrent work practices and to tolerate failure ..."

— ordering operations, detecting and resolving conflicts, propagating changes efficiently, and bounding replica divergence — and provides a comprehensive survey of techniques developed for addressing these challenges.
A Signal Analysis of Network Traffic Anomalies
- In Internet Measurement Workshop
, 2002
"... Abstract--Identifying anomalies rapidly and accurately is critical to the efficient operation of large computer networks. Accurately characterizing important classes of anomalies greatly facilitates their identification; how-ever, the subtleties and complexities of anomalous traffic can easily con-f ..."

Sympathy for the sensor network debugger
- In SenSys
, 2005
"... Being embedded in the physical world, sensor networks present a wide range of bugs and misbehavior qualitatively different from those in most distributed systems. Unfortunately, due to resource constraints, programmers must investigate these bugs with only limited visibility into the application. Th ..."

. This paper presents the design and evaluation of Sympathy, a tool for detecting and debugging failures in sensor networks. Sympathy has selected metrics that enable efficient failure detection, and includes an algorithm that root-causes failures and localizes their sources in order to reduce overall failure
Scalable information-driven sensor querying and routing for ad hoc heterogeneous sensor networks
- International Journal of High Performance Computing Applications
, 2002
"... This paper describes two novel techniques, informationdriven sensor querying (IDSQ) and constrained anisotropic diffusion routing (CADR), for energy-efficient data querying and routing in ad hoc sensor networks for a range of collaborative signal processing tasks. The key idea is to introduce an inf ..."

that the information-driven querying and routing techniques are more energy efficient, have lower detection latency, and provide anytime algorithms to mitigate risks of link/node failures. 1
Ceph: A scalable, highperformance distributed system,” in OSDI,
, 2006
"... Abstract We have developed Ceph, a distributed file system that provides excellent performance, reliability, and scalability. Ceph maximizes the separation between data and metadata management by replacing allocation tables with a pseudo-random data distribution function (CRUSH) designed for hetero ..."

for heterogeneous and dynamic clusters of unreliable object storage devices (OSDs). We leverage device intelligence by distributing data replication, failure detection and recovery to semi-autonomous OSDs running a specialized local object file system. A dynamic distributed metadata cluster provides extremely
A Fast Automaton-Based Method for Detecting Anomalous Program Behaviors
- In Proceedings of the 2001 IEEE Symposium on Security and Privacy
, 2001
"... Forrest et al introduced a new intrusion detection approach that identifies anomalous sequences of system calls executed by programs. Since their work, anomaly detection on system call sequences has become perhaps the most successful approach for detecting novel intrusions. A natural way for learnin ..."

Subdivision surfaces in character animation
- In Proceedings of the 25th annual conference on Computer graphics and interactive techniques, SIGGRAPH ’98
, 1998
"... The creation of believable and endearing characters in computer graphics presents a number of technical challenges, including the modeling, animation and rendering of complex shapes such as heads, hands, and clothing. Traditionally, these shapes have been modeled with NURBS surfaces despite the seve ..."

-ulation including a new algorithm for efficient collision detection. Third, we developed a method for constructing smooth scalar fields on subdivision surfaces, thereby enabling the use of a wider class of programmable shaders. These developments, which were used extensively in our recently completed short film
Enhancing Server Availability and Security Through Failure-Oblivious Computing
- In Proceedings 6 th Symposium on Operating Systems Design and Implementation (OSDI
, 2004
"... We present a new technique, failure-oblivious computing, that enables servers to execute through memory errors without memory corruption. Our safe compiler for C inserts checks that dynamically detect invalid memory accesses. Instead of terminating or throwing an exception, the generated code simply ..."

Detecting BGP Configuration Faults with Static Analysis
- in Proc. Networked Systems Design and Implementation
, 2005
"... The Internet is composed of many independent autonomous systems (ASes) that exchange reachability information to destinations using the Border Gateway Protocol (BGP). Network operators in each AS configure BGP routers to control the routes that are learned, selected, and announced to other routers. ..."
