Abstract: A method of receiving a set of data packets which represent a contiguous data block sent over a bus between two nodes. A memory allocation unit allocates memory beginning at a known address to a local node. The local node divides the address into multiple segments that include predetermined transaction label overlay portions. Thereafter, the local node issues request packets which include transaction labels in a header of the request packet that correspond to the predetermined transaction label overlay portions. Subsequently, a remote node sends responses, and a header of the responses includes the transaction label that corresponds to the request. The local node routes response packets to a dedicated context. The dedicated context replaces the transaction label for the transaction label overlay portion to route the response packet to a proper memory location, regardless of the order in which the packet was received.
