  • Publication number: 20240394215
    Abstract: An intermediate device 10A is the intermediate device 10A disposed between a requester 30 for transferring data using RDMA and a responder 50. The intermediate device 10A extracts a combination of a QPN of the requester 30 and the QPN of the responder 50 from a packet transmitted and received when establishing the connection, and registers the combination in a QPN table 15. The intermediate device 10A manages an MSN by a WQ table 17, and transitions the MSN number when receiving a request with a flag of Last or Only from the requester 30, and returns a pseudo-Response including the MSN after the transition.
