  • Patent number: 9753755
    Abstract: A system, and computer usable program product for addressing a workload partition are provided in the illustrative embodiments. A packet of data directed to the WPAR and including a combined address is received at a software stack. A determination is made whether the combined address includes an identifier that is reserved. If the identifier is not reserved, the identifier is used to identify the WPAR in the data processing system and the packet is sent to the WPAR. The software stack is an application configured to enable data communication using a protocol of the packet, and is modified to detect, recognize, and process the combined address for routing the packet to the WPAR. The combined address may be logically formed using an identifier associated with the data processing system and an identifier associated with the WPAR, which may be located in different portions of the packet.

  • Patent number: 7844757
    Abstract: A method and system for providing multiple input/output paths for accessing storage devices includes providing two or more logical paths between a virtual I/O client partition and a storage device and establishing a physical path between the virtual I/O client partition and the storage device by assigning the storage device to a first logical path of the two or more logical paths. The method further includes reestablishing the physical path by dynamically assigning the storage device to a second logical path of the two or more logical paths in an event of unavailability of the first logical path.

  • Publication number: 20060095365
    Abstract: A system and method are disclosed for conducting an auction in a peer-to-peer network. In one example, the method includes initiating the auction by notifying a p-commerce server of the auction's start time, end time, and item being auctioned. A bid is received for the auction directly from another endpoints, and all endpoint that have previously submitted a bid in the auction are directly notified of the received bid. The p-commerce server is instructed to stop the auction after a determination is made that the auction has ended. A highest bid from the submitted bids is identified and the endpoint that submitted the highest bid is directly notified that it has won the auction.
