  • 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.

  • Publication number: 20070132549
    Abstract: A manufacturer of an article generates a keyword, and electromagnetically writes the keyword into an RFID and prints the keyword on a guarantee card. The RFID tag is then affixed to the article, and the article is packed along with the guarantee card and shipped. When making a sale, a retail store hands over the guarantee card to a customer who buys the article. When the customer wishes to sell the article, a purchasing store reads the keyword written to the RFID tag affixed to the article and asks the customer to furnish the keyword. If the keyword furnished by the customer, by referring to the guarantee card, etc., is identical to the keyword read from the RFID tag, the customer is deemed a genuine owner of the article.
