Abstract: In a network having transaction acceleration, for an accelerated transaction, a client directs a request to a client-side transaction handler that forwards the request to a server-side transaction handler, which in turn provides the request, or a representation thereof, to a server for responding to the request. The server sends the response to the server-side transaction handler, which forwards the response to the client-side transaction handler, which in turn provides the response to the client. Transactions are accelerated by the transaction handlers by storing segments of data used in the transactions in persistent segment storage accessible to the server-side transaction handler and in persistent segment storage accessible to the client-side transaction handler.

Abstract: Data stored on a server are synchronized with corresponding data on a plurality of client computers. To facilitate synchronization of the data, the data for a class of nodes on the server are provided with a version identifier (a serial number) that is incremented each time the data are modified on the server. During synchronization, the version identifier for the data stored on the client is transferred to the server, and the nodes stored on the client are updated by downloading nodes modified on the server since the last synchronization. Data on the client that have been modified are then uploaded to the server. Collisions between nodes of the data that have been modified on two different clients are detected, and a user is given an opportunity to resolve a collision.

Abstract: A gateway provides communication of tightly coupled XA transactions to a server hosting a DBMS and makes efficient use of domain socket pairs to implement demultiplexing in the gateway. The gateway includes a TCP/IP listener process which accepts connection requests from a transaction manager. Logical agents represent the application connection and are managed by a logical agent scheduler and are passed within the gateway using domain socket pairs. Gateway agents are dedicated to identified tightly coupled XA transactions to provide tightly coupled XA transaction support for DBMS systems which do not provide such support directly. The domain socket pairs in the gateway are assigned to logical agent schedulers and are available in a domain socket pool. A wait queue is provided to buffer logical agents when connection to the server is not available or where there are no domain socket pairs available in the domain socket pool. The wait queue is itself implemented as a domain socket pair.

The results of the performed steps are then received at the terminal.

Abstract: A method and system for centralizing the LU definitions for one or a plurality of TN3270 servers. More particularly, a method and system for dynamically providing a Systems Network Architecture (SNA) Logical Unit (LU) definition for the establishment of a SNA session between a SNA client and a SNA application. The method of the present invention includes receiving a SNA session request from a telnet 3270 client, and in response thereto, retrieving a definition of a SNA LU from a table shared by one or more telnet 3270 servers. A local table within the telnet 3270 server is dynamically updating with the retrieved SNA LU definition.

Abstract: An efficient mechanism for sending messages without the use of intermediate copies (i.e. without the staging of data) is provided. In particular an interface specification which allows use users of a transport protocol is defined so as to lend itself to efficient implementations. The interface specification is a complete and robust set of user functions usable within systems desiring reliable and efficient zero copy transport protocols. Two methods are provided to accomplish the implementation of an efficient zero copy protocol. The first method is especially useful in systems where the network device has limited capabilities in terms of hardware, message fragmentation and message reassembly. An additional RDRAM memory allows data to reside in an adapter while handshake operations take place between an adapter and a node so as to specify the final destination of the data. The second method takes advantage of network devices with advanced features which are exploited for maximum efficiency.

Abstract: A system and process for streaming delivery of dynamically scalable media content over a network, such as, for example, the Internet or a wireless network, while automatically accounting for both fluctuating network bandwidth and packet loss. A system of rate-distortion based packet selection and organization is used to maximize the quality of streamed media files that have been encoded using any conventional scalable encoder. Media file quality is maximized for available bandwidth by scoring packets comprising encoded media files based on their contribution to the quality of a reconstructed media file, then preferentially transmitting those packets having the highest scores. In addition, where packets are lost during transmission, those packets that will provide the maximum rate-distortion decrease, are preferentially retransmitted prior to other lost packets which, if transmitted in the same time slot, would provide a lesser rate-distortion decrease.

Abstract: Controlling the allocation of priority for data packets within a multi-port switch includes detecting the commencement of an HTTP message; enabling the storage of an identification of the source port on which that message was received by the switch; finding correspondence between destination data of packets and the said source port; and adjusting a priority allotted to said packets in response to the correspondence. The adjustment of priority preferably increases the priority of packets forwarded to said the port relative to priority allotted packets received at the source port and thereby allots asymmetric priority to traffic between a server and a client.

Abstract: A system and method for receiving an electronic communication containing an identifier or indicia of an entity and, in response to a user's selection of the identifier, initiating communication between the user and the entity. Upon receipt of the electronic communication (e.g., document, electronic mail message, sound file), the system scans or parses it to locate one or more entity identifiers. An entity identifier may be a telephone number, electronic mail address, network address, name or virtually any other indicia that may serve to identify the entity. When a user selects an entity identifier, the system offers one or more methods of communicating with the associated entity, which methods may depend on the form of the entity identifier (e.g., a telephone number) and/or a preference specified by the user. The system initiates the selected form of communication in response to the user's selection.

Abstract: A method and system for delivering a datagram across multiple inter-network servers. The datagram is delivered from a source device having a first network level protocol to a destination device having a second network level protocol. The inter-network servers transport the datagram in accordance with a transport level protocol while the datagram has a transport priority defined by the first and second network level protocols. The source device delivers the datagram from a source port that designates the transport priority and the destination device receives the datagram at a destination port that also designates the transport priority. In accordance with the method of the present invention, either the source port or said destination port is first identified. The transport priority of said datagram is identified utilizing the transport priority designation of the identified source port or destination port. A current server capacity of each of the inter-network servers is determined.
