Abstract: A distributed system provides a quality of service by generating at least one system condition object storing a value, monitoring at least one resource in real time using the system condition object, and setting the value of the system condition object in response to the monitoring of the resource. The system determines a current quality of service based on the value stored in the system condition object. The system then regulates activity within the distributed system based on the determined quality of service.

Abstract: A system and method for accessing Internet-based and other information through a user television in a television distribution network enables a user to access and view information which is related to the programming content of a currently viewed television broadcast. This concept, known as channel hyperlinking, enables a television viewer to download Internet Web pages, and the like, which are related to a currently viewed advertisement, program, newscast, etc. To facilitate channel hyperlinking, each user of the system sends channel hyperlink requests through an upstream channel to a network headend by actuating a hyperlink button on a television remote control, for example. The network headend is interfaced to the Internet by means of an Internet Service Provider (ISP), and downloads HTML Web page data from the Internet to the requesting user.

Abstract: In an enterprise network system a plurality of software systems are integrated using an enterprise wide software management system and communicate with a plurality of clients. At least one of the clients is functionally represented by a plurality of subclients through a midware which is transparent to the software systems. Communication destined for any of the clients interfaced through the midware is received by the midware and converted to a format suitable for communication with one or more of the subclients prior to transmission thereto. Correspondingly, communications received from one or more subclients is converted to an appropriate format by the midware and forwarding to the assigned destination. Communications received by the midware is further monitored for fields which are tracked. Upon receiving communications having fields being tracked, the midware stores a least a portion of the communication in a report table.

Abstract: An information serving system includes a mobile apparatus and a terminal apparatus. The mobile apparatus includes a memory which stores ticket information including departure time data, and a display. The terminal apparatus is installed in a building, and includes a communication device, a database, and a controller. The controller controls the communication device to read the ticket information stored in the memory of the mobile apparatus, calculates a time interval between a current time and a departure time represented by the departure time data, retrieves usable facility information from the database in accordance with a length of the time interval, and causes the communication device to transmit to the mobile apparatus the retrieved usable facility information together with map information. The mobile apparatus then controls its display to display the transmitted usable facility information on a map based on the transmitted map information.

Abstract: When a client control apparatus 108 on a network connects to a camera control apparatus 102 in hyper text transfer protocol and requests the camera control apparatus 102 to transmit a file of its home page, the camera control apparatus 102 transmits a file, to the client control apparatus 108, including a description for causing the client control apparatus 108 to request the camera control apparatus 102 to transmit an applet for performing automatic reception. When the client control apparatus 108 receives this file, transmission of the applet is requested, and the server control apparatus 102 transmits the applet. Then, when transmission of state information is requested, the server control apparatus 102 transmits state information to the client control apparatus 108 only when an event indicative of a change in an angle of a camera occurs; thereby traffic of the network is reduced.

Abstract: The preferred embodiment provides an improved system and method for registration of Resource Managers with Transaction Managers in an distributed processing environment. The preferred system and method creates and stores a transactional resource in a container when the first execution method goes to the Resource Manager. The transactional resource represents the Resource Manager to the Transaction Manager. The transactional resource uses X/Open static registration procedures to inform the Resource Manager about the new transaction. The transactional resource is then registered to the Transaction Manager. In this way, only those Resources Managers that are involved in a transaction are registered and made known to registered to the Transaction Manager.

Abstract: An information network, such as the Internet (FIG. 1), uses a plurality of servers (140-142, 160, 170-171) each one of which serves only a single object (200-205), whereby the servers avoid the processing overhead involved in searching through files containing a plurality of objects for a requested object. Rather, receipt of a request by a server can only mean a request for the one object served by the server, which the server retrieves and provides to the requesting client (120). Since each server serves only one object, the client must contact a plurality of the servers in order to obtain a page (250) of information that comprises a plurality of objects.

Abstract: An improved look up mechanism for accessing a RAM to obtain forwarding information for data frames being transported among ports of a high-performance switch is provided. The look up mechanism includes a multi-page look up table and associated hashing technique. A media access control (MAC) address and a virtual local area network (VLAN) identifier are transformed with a hash function to obtain a hash key. The hash key is an address pointing to a particular entry in the look up table. A virtual first page is also derived from the hash key, which selects a particular physical page of the look up table to be initially accessed each time that MAC address/VLAN pair is used. The look up mechanism may also be used to access a short cut table containing Layer 3 short cut information. In either case, ultimately, the likelihood is increased that a match will be found on the first RAM access, thus maintaining high-speed switch performance.

Abstract: A system for multi-master unique identifier allocation comprises a server for allocating pools of identifiers to requesting servers and at least one server for requesting pools of identifiers and allocating individual identifiers as necessary. A single master server allocates “pools” of unique identifiers to network servers upon request. The network servers in turn allocate unique identifiers from their pool as necessary when the server generates new system objects. When a network server's pool of unique identifiers is nearly depleted, the network server requests an additional pool of identifiers from the master server.

Abstract: The present invention describes a method to synchronize performance data in a computer network system. All specified performance data of a single system collected by way of a network-wide uniformly clocked scanning interval are sorted according to their interval start time in ascending order and their actual scanning intervals in descending order. The first items of performance data sorted form the first common interval. All subsequent performance data are assigned to that interval, provided the mid point of their actual scanning interval falls within the common interval. The performance data which are no longer assigned to the first interval form the basis for a subsequent interval. The method is continued until all performance data are assigned to a common interval. The advantages of the present invention lie in the fact that the synchronized performance data are displayable in tabular form unambiguously and without gaps, and thus are available for postprocessing, for example as a bar chart.

Abstract: A method and apparatus in a data processing system for selectively caching web information in a cache for a browser. Web content is first retrieved by the browser during a browsing session. The web content is parsed for an indication of how the page should be stored. The web content is then stored using the indication. For example, retrieved web content may be parsed for an indication that the web content is to be removed after the browsing session terminates. Responsive to identifying the indication, the web content is cleared from the cache in response to the browsing session terminating.

Abstract: A request message is sent by a client to a server according to a first protocol (e.g., HTTP) identifying a data file and a storage location, such as an E-mail address. In response the server forwards the requested data file to the E-mail address according to a second protocol (e.g., SMTP). In doing so large amounts of data can be retrieved at a future time when network traffic is lower. Also, if the client does not have the necessary hardware/software setup, the requested data file can be retrieved by a second client which may have capability to present the information in the data file to the user. The different types of information that are capable of being handled by software operating at the client (e.g., web browser) can be handled by the E-mail software operating at the client.
