Routing with a clue
TL;DR: It is possible to speedup the IP-lookup by an order of magnitude without any major changes to the existing protocols, and in a sense this paper shows that the current routers employed in the Internet are clue-less.
Proceedings ArticleDOI
Cache index-aware memory allocation
TL;DR: It is shown that a simple adjustment within the allocator to control the spacing of blocks can provide better index coverage, which in turn reduces the superfluous conflict miss rate in various applications, improving performance with no observed negative consequences.

Space efficient fair queuing by stochastic Memory multiplexing
TL;DR: In this article, the buffer space is partitioned among queues of variable length, with the first queue long enough to accommodate the largest expected backlog, the second one long enough for accommodating the second largest expected queue, etc. Incoming messages are dequeued from the queues for transmission in Round-Robin order.
Pessimistic Software Lock-Elision
TL;DR: In this article, the authors propose a new approach for non-speculatively replacing read-write locks with pessimistic (i.e., non-aborting) software transactional code that allows readwrite concurrency even for contended code and even if the code includes system calls.
Proceedings ArticleDOI
Self-Stabilization of the Alternating-Bit Protocol
Yehuda Afek,Geoffrey Brown +1 more
TL;DR: This note presents two simple self-stabilizing data link protocols that use three sequence-numbers, and do not resort to non-volatile memory, and relax the finite-state assumptions.
