Method and system for TCP/IP using generic buffers for non-posting TCP applications
View Patent ↗Aspects of the invention for posting buffers for a non-posting TCP application may comprise posting at least one generic buffer located in a memory external to a host adapter and transferring incoming data for a TCP connection to the posted generic buffer prior to the non-posting TCP application posting a TCP application buffer for the incoming data. At least one generic buffer may be allocated from a pool of available generic buffers upon receipt of the incoming TCP connection data. At least a portion of the incoming data may be stored in the allocated generic buffer if the TCP application buffer is unable to accommodate the incoming data. The method may further determining whether the incoming data for the TCP connection transferred to the posted generic buffer is in sequence and ordering the incoming data based on a sequence number if the incoming data is out of sequence.
