Paxos Made Moderately Complex
For anybody who has ever tried to implement it, Paxos is by no means a simple protocol, even though it is based on relatively simple invariants. This paper provides imperative pseudo-code for the full Paxos (or Multi-Paxos) protocol without shying away from discussing various implementation details. The initial description avoids optimizations that complicate comprehension. Next we discuss liveness, and list various optimizations that make the protocol practical.

Controlling Queue Delay
An article by Kathleen Nichols and Van Jacobson. They expose a new algorithm, CoDel (Controlled Delay Management), for “partially” solving the bufferbloat problem, where network buffers remain persistently full:
Although essential to the operation of packet networks, buffers tend to fill up and remain full at congested links, contributing to excessive traffic delay and losing the ability to perform their intended function of absorbing bursts.
