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.

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.

A method of delivering data in an on-time manner across a communicating environment, such as multimedia data in a network or broadcast environment. The data is transmitted from a data pump at a revised transmission time which is a function of a base transmission time and a delay value. The delay value is calibrated by monitoring one or more processes between the data pump and an associated controller which receives requests from clients. The controller may include an application server which handles the requests, and a control server which processes commands from the application server and provides corresponding control functions to the data pump.

A system, method and computer program are provided for a control server in a client/server environment wherein an API framework facilitates scalable, network transparent, integrated multimedia content loading and data streaming. Concurrent real time content loading and data streaming are possible and techniques are included for admitting new streams only when they can be serviced without negatively affecting current system performance.

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.

A computer implemented method, a tangible computer storage medium, and a data processing system provide high availability support for virtual machines in a logical partitioned platform. A monitoring system detect a failure in the virtual machine. Partition management firmware then restarts the virtual machine in a consistency failover image node utilizing a consistency failover image. If a subsequent failure of the virtual machine is detected within a predetermined time, partition management firmware restarts the virtual machine in a boot failover image node utilizing a boot failover image.

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.

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.
