For decades, we have prized efficiency in our economy. We strive for it. We reward it. In normal times, that’s a good thing. Running just at the margins is efficient. A single just-in-time global supply chain is efficient. Consolidation is efficient. And that’s all profitable. Inefficiency, on the other hand, is waste. Extra inventory is inefficient. Overcapacity is inefficient. Using many small suppliers is inefficient. Inefficiency is unprofitable. —Bruce Schneier
In this post, we describe the challenges associated with measuring anycast services and propose a tool called the Border Gateway Protocol (BGP) Tuner. By using our open-source tool, operators can see in advance how changes in their BGP policies may impact the traffic load distribution over the anycast sites. This post is a short description of our technical report available here. —Joao M. Ceron
Can you really trust what a routing protocol tells you about how to reach a given destination? Ivan Pepelnjak joins Nick Russo and Russ White to provide a longer version of the tempting one-word answer: no! Join us as we discuss a wide range of issues including third-party next-hops, BGP communities, and the RPKI.
Steve Bellovin began working on networks as a system administrator, helping to build USENIX, which supports operating system research. His work as a system administrator drew his interest into security and cryptographic protection of data, leading him into working on some of the foundational protocols on the Internet.
