BGP Policies (Part 2)
At the most basic level, there are only three BGP policies: pushing traffic through a specific exit point; pulling traffic through a specific entry point; preventing a remote AS (more than one AS hop away) from transiting your AS to reach a specific destination. In this series I’m going to discuss different reasons for these kinds of policies, and different ways to implement them in interdomain BGP.
There are many reasons an operator might want to select which neighboring AS through which to send traffic towards a given reachable destination (for instance, 100::/64). Each of these examples assumes the AS in question has learned multiple paths towards 100::/64, one from each peer, and must choose one of the two available paths to forward along. This post wil consider selecting an exit point from the perspective of two more autonomous systems.
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

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.
Hedge 118: Integrating New Ideas with William Collins
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.
Hedge 117: Mike Bushong and the Product Process
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.
Why Privacy?
I’ve kicked off a series over at Packet Pushers on the ; the first installment is up now.
Hedge 116: Schofield’s Laws of Computing
Jack Schofield, a prolific journalist covering computers and computing, developed three “laws” across his thirty years of reporting that have come to be known as Schofield’s Laws of Computing. What are these laws, and how do they apply to the modern computing landscape—especially for the network engineer? Join Tom Ammon and Russ White as they discuss Schofield’s Laws of Computing.
