Hedge 127: FR Routing Update

The FR Routing project is a fully featured open-source routing stack, including BGP, OSPF, and IS-Is (among others), supported by a community including NVDIA, Orange, VMWare, and many others. On today’s episode of the Hedge, Tom Ammon and Russ White are joined by Donald Sharp, Alistair Woodman, and Quentin Young to update listeners on projects completed and underway in FR Routing.

Hedge 126: George Michaelson on ISDN

ISDN, while an old technology, is still around in many parts of the world. When will it go away? George Michaelson joins Tom Ammon and Russ White to discuss the end of ISDN. The conversation then veers into old networking technologies, and the importance of ISDN in setting the terms and ideas we use today—ISDN is one of the key technologies around which network engineers built their mental maps of how to build and maintain networks.

Our upcoming episodes for this month are George Michaelson on the death of ISDN and old networks; an update on the FR Routing project; and Rick Graziani on college and network engineering. Thanks for listening to the Hedge!

Hedge 125: Brooks Westbrook and DC Fabric Design

DC fabric design is more of an art than a science—a lot of factors come into play, such as future growth, lifecycle management, security, and costs. How can network engineers balance these various factors—how do they even know what questions to ask? Brooks Westrbook joins Tom Ammon and Russ White to discuss three- and five-stage DC fabric design, OPEX, CAPEX, and other topics on this episode of the Hedge.

Hedge 124: Geoff Huston and the State of BGP

Another year of massive growth in the number and speed of connections to the global Internet—what is the impact on the global routing table? Goeff Huston joins Donald Sharp and Russ White to discuss the current state of the BGP table, the changes in the last several years, where things might go, and what all of this means. This is part two of a two-part episode.

Hedge 123: Geoff Huston and the State of BGP

Another year of massive growth in the number and speed of connections to the global Internet—what is the impact on the global routing table? Goeff Huston joins Donald Sharp and Russ White to discuss the current state of the BGP table, the changes in the last several years, where things might go, and what all of this means. This is part one of a two-part episode.

Hedge 122: The Internet Architecture Board

What is the Internet Architecture Board (IAB) of the IETF? What role does the IAB play in the larger ecosystem of building and deploying standard protocols? In this episode of the Hedge, Tom and Ethan “flip roles” with Russ to ask these questions.

Hedge 121: Computing in the Network with Marie-Jose Montpetit

Can computation be drawn into the network, rather than always being pushed to the edge of the network? Taking content distribution networks as a starting point, the COIN research group is looking at ways to make networks more content and computationally aware, bringing compute into the network itself. Join Alvaro Retana, Marie-Jose Montpetit, and Russ White, as we discuss the ongoing research around computing in the network.

Hedge 120: Information Centric Networking with Dirk Kutscher

In today’s Internet, packets are at the core of information flows. Routers only know (very minimally) about what is in the packets they’re carrying around. Caching and content distribution networks (CDNs) are used to place information at various locations throughout the ‘net for users to access, making the distribution of this information more efficient. Information Centric Networking “flips the script,” making named information, rather than packets, the core construct of networks.

Hedge 119: Product Marketing with Cathy Gadecki

Marketing is an underappreciated (and even demonized) part of the process in creating and managing networking products. Cathy Gadecki of Juniper joins Russ White and Tom Ammon on this episode of the Hedge to fill in the background and discuss the importance of marketing, and some of the odd corners where marketing impacts product development.
