router upgrade made efficient by using redundant tcp

> 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.
