Abstract
A queued memory switch includes separate devices that switch received data to the outputs of the queued memory switch. Data is received by a first device (the master) and a second device (the slave) at a series of reception times. The slave sends information to the master indicating whether data directed to an output port was received by the slave at each of the reception times. The master stores the information from the slave with information indicating whether data directed to the same output port was received by the master at each of the reception times. The information indicates the order in which the master and slave received their respective data. The indication can be used to transmit the data from master and the slave in the order in which the data was received by the master and the slave. Related methods, systems, and computer program products are also disclosed.
