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 for checking security of data received by a computer system within a network environment is disclosed. In accordance with a preferred embodiment of the present invention, an incoming packet from a client is first decrypted within a receiving communications adapter by utilizing a master decryption key. The decrypted incoming packet is then encrypted by utilizing an encryption key identical to an encryption key employed by the client. A determination is made as to whether or not a packet produced from the encryption is identical to the incoming packet. In response to a determination that a packet produced from the encryption is identical to the incoming packet, the decrypted incoming packet is forwarded to a system memory of the computer system. As such, any incoming packet that does not meet this criterion will be rejected as a security threat.

摘要： A method for supporting peer-to-peer access across separate Peripheral Component Interconnect (PCI) host bridges within a data-processing system is described. In accordance with the method and system of the present invention, during an access request from a PCI device, a first determination is made as to whether or not the access request is for a system memory attached to a system bus. In response to a determination that the access request is not for a system memory attached to the system bus, another determination is made as to whether or not the access request is for a PCI device under the same PCI host bridge as the requesting PCI device. In response to a determination that the access request is not for a PCI device under the same PCI host bridge as the requesting PCI device, executing added protocols for the support of PCI peer-to-peer access request across separate PCI host bridges within the data-processing system.

摘要： A method in a node for managing authorized attempts to access the node. A packet is received from a source, wherein the packet includes a first key. A determination is made as to whether the first key matches a second key for the node. The packet is dropped without a response to the source if the first key does not match the second key. Information from the packet is stored in response to this absence of a match. The information is sent to a selected recipient in response to a selected event, which may be, for example, either immediately or in response to polling to see if the information is present.

摘要： A method and system for protecting electronic files from unauthorized access. The drive on which the file is stored is provided with a hardware identification code, which is unique to the drive. An Operating System (OS) extension allows a user to provide a security code required to access a requested drive. OS device driver, working in conjunction with the extension of the OS checks the requested drive to determine if an access code is required, and the drive responds with the security code or a default code. The default code indicates that the drive is globally accessible to users on the system. When a security code is returned, the OS compares the security code to the access code provided and provides the user with access to the drive only when the access code matches the security code.
