摘要： The present invention provides a computer implemented method, data processing system and computer program product for limiting instances of a client-server program within a plurality of platforms in a restricted distributed network. The data processing system receives an invocation of the client-server program. The data processing system assigns a write file to the client-server program wherein the write file has a write file name and the write file is on a distributed file system accessible to the plurality of platforms. The data processing system determines whether the write file is available. Responsive to a determination that the write file is available, the data processing system opens the write file for writing wherein the write file is associated with the client-server program. The data processing system, responsive to a determination that the write file is available, forms an addressing file having addressing information of a first instance of the client-server program.

摘要： A method, system and apparatus for improving data transfer rate over a network are provided. When a piece of data is to be transmitted to a target system, it is divided into a number of packets and a determination is made as to whether the number of packets exceeds a threshold number. If so, the packets are transferred in parallel over a plurality of network connections. The ideal network connections are TCP/IP connections. Thus, each packet has an IP header, which contains an IP identification field. An indicium is placed into the IP identification field for proper reconstruction of the data by the target system.

摘要： A method and apparatus are provided for use with a SEA or other bridge device, which is positioned between virtual and physical LANS and is adapted to monitor connection setup packets. If the SEA detects such a packet, it determines whether it can accommodate the MSS value listed in the packet. In one embodiment, a method is provided for implementation by a bridge device positioned to transfer data packets between a specified LPAR system arid a specified host. The method comprises the step of detecting a packet that is transmitted to the bridge device, in order to set up a connection between the LPAR system and the host. The method further comprises determining whether the detected packet indicates an initial MSS value for the connection that is greater than a prespecified MSS value. Upon determining that the detected packet indicates an initial MSS value that exceeds the prespecified MSS value, the packet is altered to establish the prespecified MSS value as the MSS value for the connection.

摘要： A method, system, and program for redirecting client connection requests among sockets providing a same service are provided. An application requests multiple sockets from a kernel. In addition, the application generates a socket call option to bind the sockets to a particular port number and passes a list of the sockets to the kernel, where the list indicates that the sockets will all provide access to server systems providing the same service. In response, the kernel sets up the sockets, bound to the same port, and set to reference one another. Then, when a connection request is received for a first socket in the list with a queue that is full, the kernel redirects the connection request to a second socket in the list with available queue space. Thus, rather than drop the connection request from the first socket when it lacks available queue space, the connection request is redirected to another socket providing access to the same service.
