Long-lived adaptive collect with applications
TL;DR: This work presents long-lived and adaptive algorithms for collect in the read/write shared-memory model, and presents a more pragmatic version of collect, called active set, which is slightly weaker than the collect but has several advantages.
Journal ArticleDOI
Reliable communication over unreliable channels
Yehuda Afek,Hagit Attiya,Alan Fekete,Michael J. Fischer,Nancy Lynch,Yishay Mansour,Dai-Wei Wang,Lenore D. Zuck +7 more
TL;DR: This paper investigates the possibdity of Implementing a reliable message layer on top of an underlying layer that can low packets and deliver them out of order, with the addltlonzd restriction that the implementatmn uses only a fixed number of different packets.

Flow control algorithm for high speed networks
TL;DR: In this article, a constant space algorithm for rate based flow control in large computer networks is proposed, where switches in the network dynamically measure their unused link capacity, and signal sessions with higher rates are allowed to increase their rates.
Proceedings ArticleDOI
Local stabilizer
Yehuda Afek,Shlomi Dolev +1 more
TL;DR: A local stabilizer algorithm that takes any on-line or off-line input aigorithm and converts it into asynchronous self-stabilizing algorithm (for the same distributed task), with local monitoring and repairing properties is presented.
Proceedings ArticleDOI
Time and message bounds for election in synchronous and asynchronous complete networks
Yehuda Afek,Eli Gafni +1 more
TL;DR: A lower bound of 12(nlogn) on the message complexity is proven, and it is proven that any message-optimal synchronous algo- rithm requires 12(log n) time.
