Abstract

A system for transmitting data between circuit boards within a housing. The system includes a switch card placed within a housing having a plurality of slots for holding circuit boards. The switch card includes a five gigabit switching matrix having at least a first data port and a second data port for receiving data packets. A first data bus connects a first circuit board to the first data port of the switching matrix, and a second data bus connects a second circuit board to the second data port of the switching matrix. The first circuit board transmits data to the second circuit board by transmitting to the switching matrix a data packet that is addressed to the second circuit board and that contains the data. The switching matrix receives the data packet from the first circuit board, determines which circuit board the data packet is addressed to, and then transmits the data packet to the second circuit board, thereby creating a virtual connection between the first circuit board and the second circuit board, which are both within the housing.
