Handling Churn in a DHT

by Sean Rhea, Dennis Geels, Timothy Roscoe, John Kubiatowicz - In Proceedings of the USENIX Annual Technical Conference , 2004
"... This paper addresses the problem of churn---the continuous process of node arrival and departure---in distributed hash tables (DHTs). We argue that DHTs should perform lookups quickly and consistently under churn rates at least as high as those observed in deployed P2P systems such as Kazaa. We then ..."

then show through experiments on an emulated network that current DHT implementations cannot handle such churn rates. Next, we identify and explore three factors affecting DHT performance under churn: reactive versus periodic failure recovery, message timeout calculation, and proximity neighbor selection

Online Discussion Processes: Effects of the Previous Messages ' Evaluations, Knowledge Content, Social Cues and Personal Information on the Current Message

by Gaowei Chen, Ming Ming Chiu
"... This study of the flow of online discussions examined how previous messages affected the current message along five dimensions: (1) evaluations (agreement, disagreement, or unresponsive actions); (2) knowledge content (contribution, repetition, or null content); (3) social cues (positive, negative, ..."

The Stanford FLASH multiprocessor

by Jeffrey Kuskin, David Ofelt, Mark Heinrich, John Heinlein, Richard Simoni, Kourosh Gharachorloo, John Chapin, David Nakahira, Joel Baxter, Mark Horowitz, Anoop Gupta, Mendel Rosenblum, John Hennessy - In Proceedings of the 21st International Symposium on Computer Architecture , 1994
"... The FLASH multiprocessor efficiently integrates support for cache-coherent shared memory and high-performance message passing, while minimizing both hardware and software overhead. Each node in FLASH contains a microprocessor, a portion of the machine’s global memory, a port to the interconnection n ..."

Internet Routing Instability

by Craig Labovitz, G. Robert Malan, Farnam Jahanian , 1997
"... This paper examines the network inter-domain routing information exchanged between backbone service providers at the major U.S. public Internet exchange points. Internet routing instability, or the rapid fluctuation of network reachability information, is an important problem currently facing the In ..."

HOLISTIC SCHEDULABILITY ANALYSIS FOR DISTRIBUTED HARD REAL-TIME SYSTEMS

"... This report extends the current analysis associated with static priority pre-emptive based scheduling to address the wider problem of analysing schedulability of a distributed hard real-time system; in particular it derives analysis for a distributed system where tasks with arbitrary deadlines commu ..."

Sender-based message logging

by David B. Johnson , Willy Zwaenepoel
"... Sender-based message logging is a new low-overhead mechanism for providing transparent fault-tolerance in distributed systems. It differs from conventional message logging mechanisms in that each message is logged in volatile memory on the machine from which the message is sent. Keeping the message ..."

UMAC: Fast and secure message authentication.

by J Black , S Halevi , H Krawczyk , T Krovetz , P Rogaway - In Advances in Cryptology – CRYPTO , 1999
"... Abstract We describe a message authentication algorithm, UMAC, which authenticates messages (in software, on contemporary machines) roughly an order of magnitude faster than current practice (e.g., HMAC-SHA1), and about twice as fast as previously reported times for the universal hashfunction famil ..."
