Abstract: Management of a repeater is accomplished by the repeater having segment busses connected to ports of the repeater. A switch engine forwards a packet that is broadcast onto a segment bus by a port which received the packet from an ethernet network. An arbitration unit determines which port is permitted to broadcast a packet onto a segment bus. A management unit receives an order to transfer a selected port from segment bus to a second segment bus, and the arbitration unit is activated in order to prevent any port from broadcasting a packet onto the first and second segment busses until the transfer of the selected port from the first segment bus to the second segment bus is accomplished.

Abstract: A relatively small FIFO queue is located on a semiconductor chip receiving and transmitting data in a computer system, typically a computer network. The FIFO queue has additional storage capability in the form of an expansion into the local memory of the computer system. The front and back ends of the FIFO, which are involved in receiving and transmitting data, are implemented on the chip. The FIFO expands into the space provided in the local memory only when the on-chip portion of the FIFO is full. The middle portion of the FIFO resides in expansion in the local memory. The local memory is accessed only in bursts of multiple credits, both for read transactions and for write transactions.
