Switch resources for a one-sided crosspoint switch with distributed control (i.e., switch ports, internal busses and controllers) have been organized so that modular growth is facilitated by: (1) assigning each switch port uniquely to one of the controllers; (2) making each controller handle only the crosspoints connected to the switch ports assigned to it; (3) assigning each internal bus uniquely to one of the controllers; and (4) providing a means for the controllers to communicate with each other. Modular growth of any of the switch resources (i.e., switch ports, internal busses and/or controllers) is accommodated by effectively reallocating (i.e., modifying the assignment of) some or all of the resources. Failure of a switch resource is accommodated also by effectively reallocating (i.e., modifying the assignment of) some or all of the remaining usable resources. It is contemplated that modification of resource allocation can be done in various alternative ways, either physically or electronically, including automatically and even dynamically.
