Abstract
A technique for packet processing may include maintaining a data structure representing transport status information associated with a sliding window of sequential packets for a host system. When a packet targeted for the host system is received, a packet validation process can be performed on the packet. The packet validation process may include validating that the packet belongs to the sliding window of the sequential packets by comparing the packet serial number of the packet against the packets being expected in the sliding window. The packet validation process may also include validating that the packet is being received for the first time and is not a duplicate packet. Upon validating the packet, the packet can be placed into the host system, and the status information can be updated to indicate that the packet has been received.
