1. A survivable communications network, comprising:

  • first and second manager subsystems, said first and second manager subsystems having first and second equivalent manager subsystem resources associated therewith, respectively;

    first and second central hubs, each of said first and second central hubs having first and second equivalent central hub resources associated therewith, respectively;

    a peripheral hub having peripheral hub resources associated therewith;

    a common bus capable of coupling a selectable one of said first and second central hubs to a selectable one of said first and second manager subsystems, said first central hub thereby capable of decoupling from a failed one of said first and second manager subsystems and coupling instead to an operating one of said first and second manager subsystems, said second central hub thereby capable of decoupling from a failed one of said first and second manager subsystems and coupling instead to a functioning one of said first and second manager subsystems; and

    first and second redundant channels coupling said peripheral hub to said first and second central hubs, respectively, said peripheral hub thereby capable of decoupling from a failed one of said first and second central hubs and coupling instead to a functioning one of said first and second central hubs, said network thereby able to survive failure of a selected one of said first and second manager subsystems and a selected one of said first and second central hubs.
