The Hedge 87: Jordan Holand and nPrint
The network monitoring world is rife with formats for packets being measured—every tool has its own format. What would make things a lot better for network engineers is a standard data representation for packet analysis, no matter what format packets are captured in. Jordan Holland joins Russ White and Tom Ammon on this episode of the Hedge to discuss the problem and nprint, a standard packet analysis format and tools for converting from other formats.
The Hedge 86: TCPLS
TCP and QUIC are the two primary transport protocols in use on the Internet today—QUIC carries a large part of the HTTP traffic that makes the web work, while TCP carries most everything else that expects reliability. Why can’t we apply the lessons from QUIC to TCP so we can merge these two protocols, unifying Internet transport? TCPLS is just such an attempt at merging the most widely used reliable transport protocols.
The Hedge 85: Terry Slattery and the ROI of Automation
It’s easy to assume automation can solve anything and that it’s cheap to deploy—that there are a lot of upsides to automation, and no downsides. In this episode of the Hedge, Terry Slattery joins Tom Ammon and Russ White to discuss something we don’t often talk about, the Return on Investment (ROI) of automation.
The Hedge 84: David Brown and the Root of Trust
Many engineers just assume that secure hardware boot is, in fact, secure. How does this security work, and just how secure is it, though? David Brown joins Tom Ammon, Eyvonne Sharp, and Russ White on this episode of the Hedge to discuss the secure boot loader in some detail. For more information on the secure boot loader and IoT, see David’s presentation at the Open Source Summit.
The Hedge 83: Bruce Davie and the System View
Network engineers tend to look at the world through the lens of a single device—an individual appliance, sold by a vendor, with a well-developed CLI for configuration and maintenance. Networks, however, are the “odd person out” in the world of information technology. In the broader technology world, a stronger systems-oriented view is more common. In this episode of the Hedge, Bruce Davie joins Tom Ammon and Russ White to discuss a systems view of the world, as well as a new publishing model he’s working on, and some thoughts on the place of SDN.
The Hedge 82: Jared Smith and Route Poisoning
Intentionally poisoning BGP routes in the Default-Free Zone (DFZ) would always be a bad thing, right? Actually, this is a fairly common method to steer traffic flows away from and through specific autonomous systems. How does this work, how common is it, and who does this? Jared Smith joins us on this episode of the Hedge to discuss the technique, and his research into how frequently it is used.
