ABSTRACT:
An interface for use in a data forwarding device is connected between the receive ports and transmit ports of a device. The interface ensures that data being forwarded from a receive port to a transmit port has actually been received. The interface includes a queuing circuit and a de-queuing circuit. The queuing circuit receives data from the receive port, identifies the receive port, counts the data received, and buffers the data. The de-queuing circuit retrieves the buffered data at a scheduled time based on the receive port's mode, and forwards the data to a transmit port provided that the amount of data received by the queuing circuit is at least as great as the amount of data already forwarded by the de-queuing circuit plus a threshold safe level amount of data.
