Abstract: A method, system and computer program and method for delivering a streaming data to a remote device from a wireless transmitter. In one embodiment, a transmitter is configured to send units of the streaming data to the remote device. A receiver is configured to receive usage data about the streaming data from the remote device. An adjusting module is configured to automatically adjust a transmission strategy of unsent units of the streaming data based, at least in part, on the usage data as a function of time according to a transmission policy. The usage data may include at least location information about the remote device or time of day information at the remote device. A user interface at the remote device may be configured to adjust the predefined transmission policy.

Abstract: There is disclosed a method, computer program and bridge for linking two publish/subscribe message brokers together. A subscription is made to receive request messages on one or more topics from a first broker. A subscription is made to receive all messages published at either the first or the second broker to a replyto topic including a bridge identifier. A request message is received from the first broker, the request message specifying a temporary replyto topic on which responses to the request should be published. The temporary reply to topic is modified to specify a bridge identifier. The modified request message is forwarded to a second broker. A response to the request is received from the second broker, the response being published on the replyto topic including the bridge identifier. The bridge receives the response as a result of the subscription to receive all messages published to a topic including the bridge identifier. The response is forwarded to the first broker.

Abstract: According to the present invention, there is provided a computer system, method and apparatus for making intelligent recommendations for dynamic content caching. In one embodiment of the present invention there is provided a computer implemented method for generating intelligent caching recommendations related to dynamic web content for use on a caching system. The method comprising extracting data associated with the dynamic content of interest in accordance with a predetermined data model. Next analyzing the extracted data in accordance with a plurality of certainty factors and a rule based expert system. Completing the analysis and generating a set of caching recommendations from the analyzed data suitable for use by the caching system. Implementing the recommendations in the caching system are repeated iteratively, as in a loop, automatically generating intelligent caching recommendations related to the dynamic web content for use on the caching system.

Abstract: A method of operating a resource lock for controlling access to a resource by a plurality of resource requesters, the resource lock operating in a contention efficient (heavyweight) operating mode, and the method being responsive to a request from a resource requester to acquire the resource lock, the method comprising the steps of: incrementing a count of a total number of acquisitions of the resource lock in the contention efficient operating mode; in response to a determination that access to the resource is not contended by more than one resource requester, performing the steps of: a) incrementing a count of a number of uncontended acquisitions of the resource lock in the contention efficient operating mode; b) calculating a contention rate as the number of uncontended acquisitions in the contention efficient operating mode divided by the total number of acquisitions in the contention efficient operating mode; and c) in response to a determination that the contention rate meets a threshold contention rate
