Abstract:
1. A switching controller for a dedicated bandwidth data communication switch backplane having a plurality of packet buses, each packet bus having a root and a plurality of leaves, and a plurality of other switching controllers for transmitting data on the packet buses, said switching controller comprising: a protocol domain interface adapted to receive packet data from a protocol domain; a transmit interface adapted to transmit packet data received from the protocol domain to one or more of the other switching controllers; and a receive interface adapted to receive packet data transmitted from two or more of the other switching controllers in parallel via two or more of the plurality of packet buses; a plurality of claim line interfaces adapted to exchange claiming information for the packet bus's received packet data on a plurality of claim lines with the other switching controllers, where each claim line has an association with a different one of the plurality of packet buses and interfaces with one or more of the other switching controllers; and a controller adapted to transmit a claim signal on a packet bus's associated claim line upon identifying the received packet data for capturing where the received packet data was propagated on and received from the associated packet bus.
