Broadband providers are seeing delays of more than a year when ordering internet routers, becoming yet another victim of chip shortages choking global supply chains and adding challenges for millions still working from home.

Worth Reading: Common pitfalls in RPKI deployment and how to avoid them

20 April 2021


Despite its critical role in Internet connectivity, the Border Gateway Protocol (BGP) is still highly vulnerable to different types of attacks. While widespread adoption of Resource Public Key Infrastructure (RPKI) — one of the standard ways to improve BGP security — can help, not enough network operators know about it.

Worth Reading: What Openflow teaches us about innovation

14 April 2021


For starters, the essential idea of OpenFlow was to codify what at the time was a hidden, but critical interface in the network software stack: the interface that the network control plane uses to install entries in the FIB that implements the switch data plane.

Worth Reading: Linux Network Scaling

14 April 2021


Once upon a time, everything was so simple. The network card was slow and had only one queue. When packets arrives, the network card copies packets through DMA and sends an interrupt, and the Linux kernel harvests those packets and completes interrupt processing.
