The Hedge 61: Pascal Thubert and the RAW Working Group

RAW is a new working group recently chartered by the IETF to work on:

…high reliability and availability for IP connectivity over a wireless medium. RAW extends the DetNet Working Group concepts to provide for high reliability and availability for an IP network utilizing scheduled wireless segments and other media, e.g., frequency/time-sharing physical media resources with stochastic traffic: IEEE Std. 802.15.4 timeslotted channel hopping (TSCH), 3GPP 5G ultra-reliable low latency communications (URLLC), IEEE 802.11ax/be, and L-band Digital Aeronautical Communications System (LDACS), etc. Similar to DetNet, RAW will stay abstract to the radio layers underneath, addressing the Layer 3 aspects in support of applications requiring high reliability and availability.

The Hedge 58: Michael Kehoe and eBPF

Most packet processing in Linux “wants” to be in the kernel. The problem is that adding code to the kernel is a painstaking process because a single line of bad code can cause havoc for millions of Linux hosts. How, then, can new functionality be pushed into the kernel, particularly for packet processing, with reduced risk? Enter eBPF, which allows functions to be inserted into the kernel through a sort of “lightweight container.”

Michael Kehoe joins Tom Ammon and Russ White to discuss eBPF technology and its importance.

The Hedge 57: Brian Trammell and PANRG

Brian Trammell joins Alvaro Retana and Russ White to discuss the Path Aware Research Group in the IRTF. According to the charter page, PANRG “aims to support research in bringing path awareness to transport and application layer protocols, and to bring research in this space to the attention of the Internet engineering and protocol design community.”

The Hedge 55: Nick Carter and Flock Networks

Nick Carter joins Tom and I to discuss Flock Networks. What is Flock Networks?

The Flock Networks IP routing suite is designed for unparalleled performance and massive scale. It has been implemented from scratch so it can excel on modern hardware. Each component of the IP routing suite is able to run in parallel, without being slowed down or interrupted by any other component.
