TL;DR: This paper detected what it believes were Libya's attempts to test firewall-based blocking before they executed more aggressive BGP-based disconnection during censorship episodes in Egypt and Libya.

TL;DR: This work considers the standard model of TE with ECMP and proves that, in general, even approximating the optimal link-weight configuration for ECMP within any constant ratio is an intractable feat, settling a long-standing open question.

TL;DR: This paper embarked upon a systematic algorithmic study of the resiliency of forwarding tables in a variety of models (i.e., deterministic/probabilistic routing, with packets-header-rewriting, with packet-duplication), and shows that resiliencies to four simultaneous link failures, with limited path stretch, can be achieved without any packet modification/duplications or randomization.

TL;DR: In this article, the authors present ez-Segway, a decentralized mechanism to consistently and quickly update the network state while preventing forwarding anomalies (loops and black-holes) and avoiding link congestion.
