SYSTEM AND METHOD FOR ORDERING OF DATA TRANSFERRED OVER MULTIPLE CHANNELS

摘要

A multiple channel data transfer system (10) includes a source (12) that generates data packets with sequence numbers for transfer over multiple request channels (14). Data packets are transferred over the multiple request channels (14) through a network (16) to a destination (18). The destination (18) re-orders the data packets received over the multiple request channels (14) into a proper sequence in response to the sequence numbers to facilitate data processing. The destination (18) provides appropriate reply packets to the source (12) over multiple response channels (20) to control the flow of data packets from the source (12).

1. A method for transferring data packets, the method comprising a packet source:
receiving packet data from a data source; initializing a credit counter; transmitting one or more packets over one or more network request interfaces at the packet source, wherein the credit counter is adjusted in a first direction after each of the one or more packets are transmitted over the one or more network request interfaces; receiving one or more responses over one or more network response interfaces at the packet source, wherein the credit counter is adjusted in a second direction after receiving a response of the one or more responses, each response of the one or more responses corresponding to a specific packet of the one or more packets transmitted; identifying that the credit counter has crossed a threshold value; and sending an indication to the data source, the indication identifying that the credit counter has crossed a threshold value, wherein the indication causes the data source to stop sending the packet data.
