History of the April 1 RFC

By Russ | 1 April 2020 |

This episode of the History of Networking is a little different. Because it is the first of April, we have a roundtable of several April 1 RFC authors discussing their work, and a short discussion on the history of the April 1 RFC series. The authors we have on the episode are Donald Eastlake, RFC3092, the Etymology of Foo; Richard Hay, RFC5841, TCP Option to Denote Packet Mood; Carlos Pignataro and Joe Clarke, RFC6593, Service Undiscovery Using Hide-and-Go-Seek for the Domain Pseudonym System; Carlos Pignataro, RFC6592, The Null Packet; and Ross Callon, RFC1925, The Twelve Networking Truths.

The Hedge Podcast Episode 29: Remote Work and Security

By Russ | 31 March 2020 |

The massive numbers of people staying home to work because of the ongoing pandemic are placing a lot of strain on network infrastructure. One area many operators are not considering, however, is security—how does having a lot of remote workers impact DDoS? Is split tunneling really the right way to manage remote connectivity? Roland Dobbins joins Eyvonne Sharp and Russ White to discuss security in times of mass remote work on this episode of the Hedge.

The Hedge Podcast Episode 28: Intent Based Networking in the IRTF

By Russ | 25 March 2020 | Comments Off on The Hedge Podcast Episode 28: Intent Based Networking in the IRTF

Intent based networking is on the upslope of the hype cycle right now. In this episode of the Hedge, Alex Clemm and Jeff Tantsura join Alvaro Retana and Russ White for a discussion of Intent-Based Networking – Concepts and Definitions, a draft working its way through the Internet Research Task Force.

The Hedge Podcast Episode 27: New directions in network and computing systems

By Russ | 18 March 2020 | Comments Off on The Hedge Podcast Episode 27: New directions in network and computing systems

On this episode of the Hedge, Micah Beck joins us to discuss a paper he wrote recently considering a new model of compute, storage, and networking. Micah Beck is Associate Professor in computer science at the University of Tennessee, Knoxville, where he researches and publishes in the area of networking technologies, including the hourglass model and the end-to-end principle.

History of Networking: Adrian Farrel and PCE

By Russ | 17 March 2020 |

Path Computation Element (PCE) is designed to allow the computation of paths for MPLS and GMPLS Point to Point and
Point to Multi-point Traffic Engineered LSPs. Adrian Farrel, who was involved in the early work on designing an specifying PCE, joins us in this episode of the History of Networking to describe the purposes, process, and challenges involved. You can read more about Adrian on his personal home page, and about PCE on the IETF WG page.

Hedge Podcast Episode 26: Jason Gooley and CHINOG

By Russ | 11 March 2020 | Comments Off on Hedge Podcast Episode 26: Jason Gooley and CHINOG

CHINOG is a regional network operators group that meets in Chicago once a year. For this episode of the Hedge, Jason Gooley joins us to talk about the origins of CHINOG, the challenges involved in running a small conference, some tips for those who would like to start a conference of this kind, and thoughts on the importance of community in the network engineering world.

The Hedge Podcast Episode 25: Building the Next Generation of Network Engineer

By Russ | 3 March 2020 | Comments Off on The Hedge Podcast Episode 25: Building the Next Generation of Network Engineer

If there is one thing I notice when I look around at the IETF—and many other places where I meet a lot of network operations and engineering folk—it’s that we all seem to be getting a bit older. This should lead us to an obvious question—what are we doing about bringing up a new generation of network engineers? David Huberman joins Tom Ammon and I to discuss this interesting question. David i s involved in a number of community-based efforts to train next generation network engineers, some of which he discusses in his excellent article at the APNIC blog.

History of Networking: Raj Jain and Early Transport

By Russ | 3 March 2020 | Comments Off on History of Networking: Raj Jain and Early Transport

In this episode of the History of Networking, Raj Jain joins us to talk about his early work with TCP/IP, DECnet, Frame Relay, and congestion control mechanisms. He is the co-inventor of the DEC-bit scheme for congestion avoidance in computer networks which has been adapted for implementation in Frame Relay networks as forward explicit congestion notification (FECN), ATM Networks as Explicit Forward Congestion Indication (EFCI), and TCP/IP networks as Explicit Congestion Notification (ECN).

The Hedge Podcast Episode 24: Single Source of Truth

By Russ | 26 February 2020 | Comments Off on The Hedge Podcast Episode 24: Single Source of Truth

Tim Schreyack recently presented at NANOG on the topic of building a single source of truth for network automation. Tim joins Tom and Russ in a wide-ranging discussion about single sources of truth, changing the way we see the network, and the changing skills of network engineers.

The Hedge Podcast Episode 23: The MOPS Working Group

By Russ | 19 February 2020 | Comments Off on The Hedge Podcast Episode 23: The MOPS Working Group

The IETF works on many things beyond IP and routing—the Media Operations (MOPS) working group is gathering input on media-related operational issues and practices, including “proposed technologies related to the deployment, engineering, and operation of media streaming and manipulation protocols and procedures in the global Internet (inter-domain) and within-domain networking.” Leslie Daigle and Eric Vyncke, the co-chairs of the MOPS working group, join Alvaro Retana and Russ White to discuss the work they are doing.
