WAN Architecture

Wide-area transport, carrier strategy and circuit design — from bonded serial links to intercontinental telemetry and diverse carrier entry.

Left to right is time. Each row is one of the 17 disciplines this one worked alongside, ordered so kindred disciplines sit next to each other rather than alphabetically — a landscape only means anything if neighboring rows belong together. Height is the work running in that domain in that year, weighted by what failure would have cost — life-safety ×3, a statutory obligation ×2.2, the estate itself ×1.5, an evaluation ×1. Every project declares which of those it was, so each ridge traces to an entry you can open and disagree with. Only the work that used this technology is counted, so what shows here is the company it kept rather than the record around it. Height and color are on the record-wide scale rather than this page’s own, so a modest estate draws a modest landscape and any two of these pages can be read against each other.

Wide-area design across enterprise, government, industrial and utility estates: carrier services and circuit strategy, transport selection, and building resilience into paths that cross other people’s infrastructure.

Diversity that exists only on a carrier’s paper map tends to converge in a single conduit somewhere, which is why so much of this work ended up running over assets the client owned.
