ABSTRACT:
Certain aspects of the invention provide handling out-of-order TCP segments and may include placing a first received segment in a host buffer and determining whether a second received segment is an in-order or out-of-order (OOO) segment. Control information associated with OOO segments may be stored locally on a network interface card (NIC) and the OOO segment placed in a host buffer rather than on the NIC. An address or location occupied by an end of the first received segment may be recorded and stored on the NIC. As in-order and/or OOO segments are received, control information associated with a starting address and/or end address may be stored on the NIC. Accordingly, as subsequent in-order and/or OOO segments are received, they may be correctly placed within the host buffer based on the recorded and/or stored control information without being buffered on the NIC.
