Method and apparatus for implementing queue pair connection protection over infiniband

A computer program product for implementing queue pair connection protection in an interconnect network system, said computer program product including a plurality of computer executable instructions stored on a computer readable medium, wherein said instructions, when executed by the network system, cause the network system to perform the steps of:

• receiving a message packet for a queue pair (QP);
• checking for an imminent connection failure for the QP;
• responsive to identifying said imminent connection failure, establishing a special message processing mode for the QP;
• and
• responsive to establishing said special message processing mode, receiving packets of the message without establishing a message queue entry and without storing packet data.

Apparatus for implementing queue pair connection protection over an interconnect network comprising:

• a packet disassembler for receiving a message packet for a queue pair (QP) and for checking for an imminent connection failure for the QP;
• a queue pair context memory for storing a special message processing mode bit for each queue pair;
• and
• said packet disassembler responsive to identifying said imminent connection failure, for storing said special message processing mode bit for establishing a special message processing mode for the QP;
• and responsive to establishing said special message processing mode, for receiving packets of the message without establishing a message queue entry and without storing packet data.
