router upgrade made efficient by using redundant tcp

[ post by non-subscriber.  with the massive amount of spam, it is easy to

Without changing TCP functionally, that is its interface, I present a way to
suffer a router outage seamlessly that is, to the degree all other standards
are followed.      Where the router switched to has functionality that is a
superset of the one in outage, those parts of the equivalency set are
carried over.   Please review my document, I hope it is easily read and
understood.   The functionality has shown great promise in the lab.
Please feel free to comment in whatever form.
