The TED isn’t the LSDB
In traffic engineering discussions, it’s common to hear the Traffic Engineering Database (TED) described as an “extension” of the Link State Database—as if the TED is simply the LSDB with a few extra bits. The implication is that traffic engineering is just normal routing with more metadata, and that the distinction is mostly academic. That…
State, Signaling, and the Cost of Simplified Narratives
This article is not a comparison of protocols, nor an argument for or against any specific traffic engineering architecture. Instead, it is an examination of how architectural narratives form, how they simplify complex histories, and how those simplifications can quietly shape design assumptions long after the original context has faded. One of the most persistent…
Think Abstract not Explicit
When we talk about path computation in networks, we often frame it as a technical problem: algorithms, constraints, and optimization. But in practice, it’s just as much a human problem. We don’t think in terms of individual links and nodes all day long. We think in regions, failure domains, performance expectations, and operational boundaries. We…
