摘要： A method and implementing apparatus is provided for transferring data from memory to a file decoder which is effective to decode the file for further processing. In an illustrated example, a video file is decoded for presentation on a display device. The methodology includes enabling a plurality of control functions for access by a user or a user system in controlling the identity, sequence and flow of file transfers in order to optimize transfer efficiency in a data transfer transaction. Application programming interface (API) calls are provided by which playlists are constructed for transfer to the decoder. Further API calls are provided to enable pause and seek functions to be activated during a file transfer. A registration methodology is also provided by which predetermined processing events may be selected and recorded as they occur. The process further includes a methodology for modifying the file transfer protocol between multiple copy transfer and minimal copy transfer depending upon the type of data transfer channel being implemented.

摘要： A method and implementing apparatus is provided for transferring data from a first device to a second device through a system coupling call. The coupling methodology is implemented to effect a direct coupling between a data producing device and a data receiving device such that data transfers between devices is passed more directly between devices with only minimal copying of the data during the transfer process. The coupling subsystem enables the construction of coupling modules which provide services and afford the opportunity to optimize the transference of data between two devices and permit the dynamic construction of coupling modules to provide coupling service between any pair of devices. In one example, video calls have been created to interface within the new data coupling environment.

摘要： A computer implemented method, data processing system, and computer program product for enabling network statistics to be collected per software partition. When an incoming data packet is received at the Internet Protocol (IP) layer of an operating system, the IP address in the incoming data packet is identified. The IP address in the incoming data packet is then compared against IP addresses stored in a hash table, wherein the hash table maps each IP address in the hash table to a software partition of the operating system. If an IP address in the hash table matches the IP address in the data packet, the software partition mapped to the located IP address in the hash table is identified. Network statistics collected for the incoming data packet are then associated with the software partition.

摘要： A method and system for handing-off TCP states in a communication network. Specifically, the present invention allows for handing-off TCP states between nodes in an associated network that is optimized for rare handoff of TCP states. The handoff occurs between dynamically loadable modules that wrap around the TCP/IP stack located at a front-end node and a selected back-end web server. A handoff protocol implemented by the loadable modules works within the kernel level of the existing TCP/IP code. As such, no changes to the existing TCP/IP code is necessary. The loadable modules at the front-end are able to select a back-end web server depending on the content of the web request, coordinate handing off TCP states, and forward packets to the back-end web server. Loadable modules at the selected back-end modify response packets going out to reflect the proper TCP state of the front-end node.

摘要： A computer implemented method, apparatus, and computer program product for managing state data in a workload partitioned environment. Process state data for a process in a workload partition is saved. Process state data is used to restore the process to a given state. State data associated with open sockets and open files bound to the first process is saved. In response to a determination that the process is associated with a domain socket that is bound to a socket file, an absolute pathname for the socket file is saved. A domain socket associated with a connecting process in the workload partition uses the socket file to connect to a domain socket associated with a listening process in the same workload partition to enable the two processes to communicate with each other.

摘要： The present invention provides a computer storage server implemented method for generating attribute streams. The storage server receives a request from an application to write data to at least one storage object, the request having a request type. The storage server then updates an attribute stream with metadata associated with the at least one storage object. The storage server also updates the attribute stream with the at least one checksum, such that the attribute stream is associated with the at least one storage object. The storage server determines the request type to be one selected from among the group consisting of an email type, a file transfer protocol type, and a hypertext transfer protocol type. Responsive to a determination that the request type is among one selected from the group consisting of an email type, a file transfer protocol type, and a hypertext transfer protocol type, the storage server verifies the application. Based on the determination of the request type, the storage server then updates the attribute stream by applying a filter among one selected from the group consisting of an email attribute stream filter, file transfer protocol attribute stream filter and a hypertext transfer protocol attribute stream filter.

摘要： A computer implemented method, apparatus, and computer program product for checkpoint and restart of a process. In one embodiment, a process shell representing a restartable process is created on an arrival server in response to identifying a process on a departure server that is a restartable process. The process shell is frozen. A name of the restartable process, an identifier of the restartable process, and an identifier of a parent process of the restartable process is assigned to the process shell. The process shell is then unfrozen and exits. A parent process restarts the restartable process when the process shell exits.
