I think hop by
hop routing with dynamic reconfiguration was bit of an
innovation.
Very much so - I do not doubt that. However, all that hop-by-hop and
reconfiguration stuff was built on Ma Bell's work. Hop by hop? Well,
that can be found in the section about how a call is routed from the
local exchange, up the hierarchy to the long-lines people, and back
down to another local exchange. In a "complex" call, like Ichibutt, NC
to Bumbledweeb, ME, there may be four or five hops needed to complete
the call. And the reconfiguration? Essentially grabbing on to the ever
changing pool of free trunks and long lines.
