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 (912) 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 (912) 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 (902) 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 (902) and/or OOO segments are received, they may be correctly placed within the host buffer (912) based on the recorded and/or stored control information without being buffered on the NIC.
