Well sure. But are you familiar with how the hardware works in the
high-end routers? The stuff is seriously expensive to build,
especially in the relatively low quantities that populate the core of

The current kit deals with packets rather than flows. Flows was
investigated thoroughly and looks very much like a blind alley. It has
some useful niches but the failure modes are catastrophic.
Granted someone could stumble on a brilliant insight tomorrow,
especially if under pressure to innovate,. But understand that you're
talking about a scientific advance, not a technological advance.
Technology can be predictably built from the existing science at
demand. Scientific advances are unpredictable; they happen almost at
random. If you're a betting man, don't bet on the timely discovery of
science that doesn't yet exist and right now the science of routing is
Tries or TCAMs.
