METHOD AND APPARATUS FOR ENABLING IDENTIFIER BASED STREAMS OVER PCI EXPRESS BUS Russian patent published in 2014 - IPC G06F13/14 

FIELD: information technology.

SUBSTANCE: apparatus for ordering packets includes a memory ordering logic to order packets to be transmitted over a serial point-to-point interconnection, the memory ordering logic being able to selectively bypass a stalled posted request and transmit over the port a non-posted request that was received after the stalled posted request if a header of the non-posted request indicates the non-posted request is order independent and if the header of the non-posted request includes a requestor identifier different from requestor identifiers of posted requests received earlier; and selectively bypass a stalled posted request from and transmit over the port a completion packet that was received after the stalled posted request if a header of the completion packet indicates the stalled posted request is order independent and if the header of the completion packet includes a completer identifier different from requester identifiers of posted requests received earlier.
