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.

The Hedge 26: Jason Gooley and CHINOG

By Russ | 11 March 2020 | Comments Off on The Hedge 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 25: Building the Next Generation of Network Engineer

By Russ | 3 March 2020 | Comments Off on The Hedge 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 24: Single Source of Truth

By Russ | 26 February 2020 | Comments Off on The Hedge 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 23: The MOPS Working Group

By Russ | 19 February 2020 | Comments Off on The Hedge 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.

Early Internet and IAB History with David Clark

By Russ | 18 February 2020 | Comments Off on Early Internet and IAB History with David Clark

The Internet Architecture Board “provides long-range technical direction for Internet development, ensuring the Internet continues to grow and evolve as a platform for global communication and innovation.” David Clark joins Donald Sharp and Russ White to discuss the origins of the IAB, and relate his experience in the early days of the Internet.

The Hedge 22: Challenges in Deploying IPv6 in the Enterprise

By Russ | 12 February 2020 | Comments Off on The Hedge 22: Challenges in Deploying IPv6 in the Enterprise

Most transit providers, content providers, and IX’s have deployed IPv6—but many enterprise network operators have not. Ed Horley joins us at the Hedge for a wide-ranging conversation on the challenges of deploying IPv6 in enterprise networks, IPv6 penetration, and other intersecting topics. Ed cohosts the IPv6 Buzz podcast at Packet Pushers, blogs at howfunky.net, and writes at the IPv6 Center of Excellence. You can also find Ed on Twitter and LinkedIn.

The Hedge 21: Industry Standard Network Design

By Russ | 5 February 2020 | Comments Off on The Hedge 21: Industry Standard Network Design

On this episode of the Hedge, Phil Gervasi joins Tom Ammon for a conversation that starts with industry standard network design, but ends up covering a wide range of topics.

The History of the Early Internet and Measurement: Jon Crowcroft

By Russ | 4 February 2020 | Comments Off on The History of the Early Internet and Measurement: Jon Crowcroft

The early Internet was not only about designing transport protocols, developing control planes, and understanding how to build faster physical transports. Measurement played a huge role in understanding what needed to be changed, what needed to be developed and understanding why the protocols that make the Internet (and other networks) “go” really work. John Crowcraft, one of the pioneers in measuring network things, joins this episode of the History of Networking to discuss this history.
