摘要： A method and system for a merchandise checkout system utilizes a remote scanning device, a shopping cart and bags for allowing a purchaser to buy merchandise unassisted by store personnel. The remote scanning device reads product identity information from coded levels on products chosen by the purchaser and sends the information to a central processor. The central processor has a memory, which indexes price information and weight for each product based on the product identity information. The central processor sends an accumulated price and weight transaction to the remote scanning device for the purchaser's use. The product identity information on the products further include a security tag device which is deactivated by the remote scanning device. The purchaser upon completion of their purchases takes their shopping cart to a security station for weighing in on a scale wherein an actual combined weight of the shopping cart, bags and products is compared to a predicted weight determined by the central processor and generating a notification signal if a discrepancy occurs. The security station further verifies that the security tag devices have been deactivated and also generates a notification signal. The purchaser next goes to a payment checkout terminal coupled to the central processor, wherein the payment checkout terminal effects financial transactions including acceptance of payment for transactions initiated by the remote scanning device, and the payment checkout terminal is operable by store personnel only.

摘要： A system and method for establishing multiple connections using a private data field of a communication management protocol is provided. With the present invention, a Service ID identifies a specific consumer and the private data field contains a list of connection attributes for each connection that is to be established. An active side requests a connection and the passive side replies to the connection request. The active side sends the passive side a connection establishment request. This connection establishment request includes a Service ID which identifies a passive side process associated with a service. This connection establishment request also includes communication attributes of one or more connected services and datagram services associated with the Service ID. The passive passes the connection request to a process associated with the service. If the passive side process does not wish to carry out the service, a negative reply message is returned to the active side. If the passive side process does wish to carry out the service, a positive reply is returned to the active side and the reply includes the communication attributes for the connection and unreliable services associated with the Service ID used in the connection establishment request.

摘要： A method, system, and product in a data processing system are disclosed for managing data transmitted from a first end node to a second end node included in the data processing system. A logical connection is established between the first end node and the second end node prior to transmitting data between the end nodes. An instance number is associated with this particular logical connection. The instance number is included in each packet transmitted between the end nodes while this logical connection remains established. The instance number remains constant during this logical connection. The instance number is altered, such as by incrementing it, each time a logical connection between these end nodes is reestablished. Thus, each packet is associated with a particular instance of the logical connection. When a packet is received, the instance number included in the packet may be used to determine whether the packet is a stale packet transmitted during a previous logical connection between these end nodes.

摘要： A method for determining parameters needed to communicate with a remote node in a computer network is provided. The invention comprises determining the location of the remote node to which an InfiniBand (IB) node might desire to communicate. This resolution comprises determining the location of the remote node based on a desired application or service, and then determining the IB parameters needed to communicate with the remote node. The resolution might also involve determining the specific queue pairs that associated with the service dynamically. The general solution is applied to IP service resolution.

摘要： A method and implementing computer system are provided which allows for significantly improved input/output (I/O) subsystem designs in all systems which include serialized I/O transactions such as so-called Express specification systems. Transaction control methodology is implemented to improve Express design requirements for Express devices such as an Express switch, Express-PCI bridge, endpoint, and root complex. This is accomplished by utilizing improved transaction ordering and state machine and corresponding buffer design and improved flow control credit methodology which enables improved processing for controlling transactions flowing through Express devices including Express switches and Express-PCI bridges. An Express-PCI/PCIX transition bridge design is also provided, along with the flow control credit methodology and implementation within the Express-PCI/PCIX bridge design to enable efficient interfacing between Express and legacy or existing PCI/PCIX systems.

摘要： A bus bridge including a buffer pool and steering logic where the buffer pool is organized as a plurality of buffers sets including at least first and second buffer sets and the steering logic is adapted to store transactions originating with a first peripheral device in the first buffer set and transactions originating with a second peripheral device in the second buffer set. Transactions may arrive via a secondary bus, such as a PCI bus, coupled to the bus bridge. The bridge further allows relaxed transaction ordering rules compared to conventional PCI transaction ordering rules by identifying transactions by grant signals and thus allows steering of transactions from the first and second devices to first and second buffer sets respectively. The bridge is suitably adapted for combining or merging two or more transactions within each buffer set. Each buffer set preferably includes one or more buffers for temporarily storing transactions arriving from the secondary bus and bound for a primary bus. The primary bus may comprise a host bus connected to one or more processors or an additional PCI bus or other peripheral bus. The invention further contemplates a computer system including at least one processor, a bridge coupled to the processor via a host bus, and a plurality of peripheral devices including first and second peripheral devices coupled to the bridge via a secondary bus. In one embodiment, the bridge is configured to receive first and second request signals from the first and second peripheral devices respectively. The bridge preferably further includes arbitration logic for arbitrating mastership of the secondary bus in response to the request signals to produce first and second grant signals. The steering logic is suitably configured to utilize the first and second grant signals to determine the source of a subsequent transaction.

摘要： A bus bridge including a buffer pool comprised of a first and a second buffer sets. The first and second buffer sets are associated with first and second peripheral devices respectively. The bridge is configured to receive an interrupt and identify the interrupt source. A buffer set associated with the interrupt source is selected and transactions in the selected buffer set flushed prior to forwarding the interrupt to a processor. The bridge is preferably configured to identify the interrupt source by receiving a first interrupt signal from the first peripheral device and a second interrupt signal from the second peripheral device. Preferably, the bridge is configured to flush the transactions by pushing them into system memory via a primary bus such as a host bus of a processor. The invention further contemplates a system including a processor coupled to a host bus, a system memory, a bus bridge as described coupled between the host bus and a secondary bus, and first and second peripheral devices coupled to the secondary bus. Upon receiving an interrupt, the bridge is configured to identify the interrupt source, select a buffer set associated with the interrupt source, and flush posted memory write transactions in the selected buffer set, all prior to forwarding the interrupt to the processor. In one embodiment, the bridge, the first and second peripheral devices, and the secondary bus are compliant with the PCI specification. The bridge is configured in one embodiment to receive unique first and second interrupt signals from the first and second peripheral devices respectively.
