The Hedge

You can register for my network troubleshooting course here.

Information about the IEEE Network Softwarification Conference can be found here.

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!

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.

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.

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.

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.

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.

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.

When vendors build something new—or when you decide to go a different direction in your network—you have to figure out how to integrate these new things. Integration of this type often includes cultural, as well as technical, changes. William Collins joins Tom Ammon and Russ White to discuss his experience in integrating new technologies on Hedge 118.

Continuing our series on how vendors build networking products, Mike Bushong joins this episode of the Hedge to discuss the overall process, the importance of the product manager, and the importance of managing and selling change. Join Tom Ammon, Eyvonne, and Russ White as we discuss how vendors build products.
