System and method for ordering of data transferred over multiple channels

A non-transitory computer readable storage medium having embodied thereon a program executable by a processor to perform a method for transferring data over multiple channels, the method comprising:

• receiving a plurality of data packets over a plurality of request channels from a first computing device, wherein at least some of the plurality of received packets are received out-of-order;
• storing each of the received data packets of the plurality of data packets in a re-order buffer;
• setting one or more bits, wherein each of the one or more bits set identify that at least a portion of the re-order buffer contains valid packet data, wherein
• a first bit of the one or more bits set include a packet valid bit for each of the received data packets,
• the one or more bits set include a next sequential valid bit,
• the next sequential valid bit associated with an immediately preceding valid bit that corresponds to at least an immediately preceding portion of the re-order buffer, and
• at least one packet of the received packets stored in the re-order buffer is provided to the destination based on the immediately preceding valid bit being set;
• transmitting a response for each of the received data packets over one or more response channels;
• and
• providing the one or more of the received data packets to a data destination in-order based on the one or more bit settings.

A system for transferring data over multiple channels, the apparatus comprising:

• a first computing device;
• a second computing device;
• a plurality of request channels;
• and
• one or more response channels, wherein:
• receiving a plurality of data packets are received by the second computing device, wherein the plurality of packets are transmitted from a first computing device to the second computing device over the plurality of request channels, and at least some of the plurality of received packets are received out-of-order;
• each of the received data packets of the plurality of data packets are stored in a re-order buffer;
• one or more bits are set,
• a first bit of the one or more bits set include a packet valid bit for each of the received data packets,
• the one or more bits set include a next sequential valid bit,
• the next sequential valid bit associated with an immediately preceding valid bit that corresponds to at least an immediately preceding portion of the re-order buffer, and
• at least one packet of the received packets stored in the re-order buffer is provided to the destination based on the immediately preceding valid bit being set;
• each of the one or more bits set identify that at least a portion of the re-order buffer contains valid packet data,
• a response for each of the received data packets are transmitted over one or more response channels, and
• the one or more of the received data packets are provided to a data destination in-order based on the one or more bit settings.
