摘要： The invention relates to regulating access by users to a scarce resource, wherein the resource is capable of handling multiple concurrent accesses. A request for access to the scarce resource is received and it is determined whether the access level for the scarce resource is at a desired maximum. Responsive to determining that said access level is at a desired maximum, the requester is placed in a queue for access to said scarce resource. The requester is then provided with a notification that the request has been enqueued. Access is available to the requester upon reaching the head of the queue when the access level drops below the desired maximum.

摘要： A server computer connectable to a network and having a plurality of processors (20, 30, 40) arranged to provide a service to one or more client computers connected to the network. The service Involves the provision of blocks of information to a client computer (50), and the processors have access to a data storage (120) in which data for the blocks of information is stored. Each processor in the server has block retrieval means (80), employed in response to a request from a client computer (50) for a particular block of information from that processor, to retrieve data from the data storage (120) to construct a file representing the requested block of information, the file including references to subsequent blocks of information requestable by the client (50). Additionally, load determining means (100) periodically determines activity data for the processor for inclusion In a load distribution record maintained for all of the processors of the server. Decision means (90) is then used which, for each reference to a subsequent block of information in the file constructed by the block retrieval means (80), determines, based on the load distribution record, which processor should service a request from the client computer (50) for that subsequent block of information, and includes an address for that processor in the file constructed by the block retrieval means (80). The file is then sent to the client computer (50).In preferred embodiments, the service being provided is the World Wide Web (WWW) service, and the technique Is employed on a parallel Web server providing Web pages to clients over the Internet.

摘要： A publish/subscribe interface is used to enable a non-publish/subscribe first system (such as an IP network device) to obtain status information about a publish/subscribe device that cannot be pinged by the first system. The first system sends a status request to a domain name server associated with a system known to include the publish/subscribe device. The status request includes a domain name for the publish/subscribe device. Topic space maintained by a message broker in the publish/subscribe system includes status topics associated with publish/subscribe devices. The status topics contents reflect the current availability of the associated publish/subscribe device. The domain name is mapped to a status topic associated to the publish/subscribe device identified in the status request and the contents of that status topic are retrieved. If the contents have a first value, a “good” IP address is returned to the first system. If the contents have the second value, a “bad” IP address is returned. The return address is used in ping messages. If the ping operation succeeds, it is concluded the publish/subscribe device is online. If the ping operation fails, it is concluded that the publish/subscribe device is off-line.
摘要翻译： 发布/订阅界面用于使非发布/订阅第一系统（例如IP网络设备）能够获得关于由第一系统无法ping通的发布/订阅设备的状态信息。 第一个系统向与已知包含发布/订阅设备的系统相关联的域名服务器发送状态请求。 状态请求包括发布/订阅设备的域名。 发布/订阅系统中由消息代理维护的主题空间包括与发布/订阅设备相关联的状态主题。 状态主题内容反映了相关发布/订阅设备的当前可用性。 域名被映射到与状态请求中标识的发布/订阅设备相关联的状态主题，并且检索该状态主题的内容。 如果内容具有第一个值，则会将第一个系统返回“良好”IP地址。 如果内容具有第二个值，则返回“坏”IP地址。 返回地址用于ping消息。 如果ping操作成功，则发布/订阅设备在线。 如果ping操作失败，则得出结论，发布/订阅设备是离线的。

摘要： The present invention provides methods, apparatus and computer programs for event-based control of subscription matching in a publish/subscribe communications environment. Activation and/or deactivation events are associated with subscriptions at a publish/subscribe broker and are used to control when a subscription is active. The broker is responsive to temporally-unpredictable events, such as receipt of a published message on a predefined activation topic, to activate subscription matching for messages that are subsequently received or which have been received earlier and retained at the broker. Conventional subscription matching can be avoided for a registered subscription while that subscription is inactive, and subscribers are not required to explicitly and repeatedly subscribe and unsubscribe.

摘要： A name server computer and method of operating such a computer, for facilitating a connection of a program on a client computer to a server, the server consisting of a plurality of server computers with shared resources. The name server computer, the client computer, and the server computers all reside in a logical network. The name server computer receives a request from the client computer for a computer address of a server computer identified by a server computer name sent with the request, such computer address enabling a connection to be made from the client computer to that server computer via the network. A list of server computer names with their computer addresses is provided. The name server computer uses the list to convert the server computer name received from the client computer into the computer address of the server computer, and then sends the computer address to the client computer. The computer further includes decision logic for studying the server computers at predetermined intervals having regard to a predetermined test criteria, to select one of the server computers. The list is then updated by associating the computer address for the server computer selected by the decision logic with a particular server computer name contained as a generic server computer name in the list. Using this technique, when a client computer specifies the generic server computer name, it receives the computer address of the server computer identified by the decision logic.

摘要： A hierarchical publish/subscribe network is employed to produce and distribute special effects to users to complement displayed video information. A top level broker in the network receives a plurality of data streams corresponding to a respective plurality of primary special. A service provider makes a subscription request for one of said primary special effects and receives the corresponding selected data stream. The selected data stream is transformed into at least one further data stream, corresponding to a further special effect. The further data stream is published to a lower level broker associated with the service provider. In response to a user subscription request for the further special effect, the lower level broker publishes the further data stream to a user interface for presentation to the user in association with the displayed video information.

摘要： Provided is a data transmission method, a communications network, a mobile receiving device and data processing methods for use in broadcast of geographic information to mobile devices. The invention overcomes the problem of lack of currency of static information distribution via CD-ROM, and the problem of the cost of lengthy connections to the Internet which is a requirement of some dynamic solutions. The geographic data which is relevant to a transmitter in the network is broadcast by the transmitter as a plurality of separate data elements which each relate to and include an identification of a specific map segment of a segmented map, such that the data elements can be transmitted independently of each other and the map segment identifier can be used by the receiving device to position the geographic information of each data element within the appropriate map segment. Each data element is retransmitted periodically such that gaps can be filled in and the map can be built up over time even if transmission failures occur during a transmission.
