A method and system for controlling message throughput rates of clients connected to a broker device in a publish/subscribe network are disclosed. The broker device determines a maximum allowable message throughput for each client connected to the broker device. If a message-producing rate of a client exceeds the maximum allowable message throughput of the client, the broker device sends a negative acknowledgement (NACK) packet to the client and messages from the client are not accepted at the broker device. The NACK packet includes a maximum allowable message throughput of the client, so the client can adjust its message-producing rate based on the maximum allowable message throughput of the client. The present invention can be applied to a publish/subscribe network as well as a TCP/IP network.

A method of assisting a user, for use in an environment comprising: a user session, an external entity session and a forms engine for generating a form. The method comprises the steps of: registering with the user session, wherein a first session is established between the user session and the forms engine; receiving a request for assistance from a user; in response to receiving the request, de-registering with the user session, wherein the first session is un-established; registering with the external entity session, wherein a second session is established between the external entity session and the forms engine; receiving input from the external entity session; and populating the form with the received input.

One or more policies to be applied to a set of one or more messages in a message oriented middleware are defined. Metrics of the message oriented middleware are monitored. Application of a policy in response to a trigger condition being satisfied is initiated. Application of the policy applies actions across the set of one or more messages.

An exemplary embodiment includes a method for pairing an application name and a client ID in a messaging broker infrastructure, the method including running a messaging system associated with the messaging broker infrastructure running a monitoring application configured to monitor a connection to the messaging broker, creating a connection to the messaging broker, identifying a class name and the client ID associated with an application, converting the class name to an application name and publishing a pairing of the application name and the client ID on the messaging infrastructure.

Embodiments of the present invention provide an approach for a publisher-assisted, broker-based cache that can be utilized to reduce a volume of data (e.g., network traffic) delivered between a publisher and broker in a publication/subscription (pub/sub) environment. Specifically, in a typical embodiment, when a message is being generated on a publisher system, the publisher system will determine if the message includes a set of data that has a potential to be repeated in subsequent messages. Once such a set of data has been identified, the set of data will be associated/marked/tagged (e.g., in the message) with a unique identifier/cache key corresponding thereto (i.e., to yield a modified message). The modified message will be sent to a broker system, which will detect/locate the unique identifier, cache the corresponding data, and send the message along to any applicable subscriber systems. When a subsequent message that is supposed to contain the cached set of data is generated, the publisher system will instead substitute the unique identifier for the set of data to yield an abbreviated message and send the abbreviated message to the broker system. Upon receipt, the broker system will detect/locate the unique identifier, retrieve the corresponding set of data from the cache, replace the unique identifier with the set of data to yield a completed message, and then send the completed message to the applicable subscriber systems.

In general, embodiments of the present invention provide an approach for caching potentially repetitive data in a publication-subscription (pub/sub) system. Specifically, in a typical embodiment, when a message is received on a broker system from a publisher system, the broker system analyzes the message for potentially repetitive data. Such data can be determined from historical messages (e.g., determining that a certain set of data appeared in multiple messages and is thus flagged in a database or the like), a set of rules (e.g., if data set “Y” appears, flag it as potentially repetitive), etc. Regardless, once such a set of data has been identified, the set of data will be tagged/marked in the message with a unique identifier. The message and inserted unique identifier is then sent to the relevant subscriber system(s). Upon receiving the message, the subscriber system(s) will analyze the message, identify the unique identifier, and cache the tagged data. Thereafter, when the publisher system receives another message that contains the same set of data that was previously tagged, the publisher system will substitute the unique identifier for the repeated data to yield an abbreviated message. The publisher system will then send the abbreviated message to the subscriber system(s), which will analyze the abbreviated message, identify the unique identifier, and retrieve the associated data from cache. Thus, the substitution of unique identifiers for potentially repetitive data can avoid unnecessary communication of data and reduce overall network bandwidth consumption.

A method, a system and a computer program product for matching a publication to at least one subscriber are disclosed. After receiving a publication request, a matching engine accesses a hash table to determine whether there is a non-wildcarded match corresponding to the publication request. If the matching engine finds the non-wildcarded match in the hash table, the matching engine omits validating a topic of the publication and provides the non-wildcarded match to the broker device without waiting for a result of searching a wildcarded match. Otherwise, the matching engine validates the topic of the publication. The matching engine also starts to search a wildcarded match in a wildcarded subscription data store. Upon finding the wildcarded match, the matching engine provides the wildcarded match to the broker device. The matching engine provides each result of the findings asynchronously to the broker device.
摘要:
A system for transmitting an input stream for use with an apparatus comprising a plurality of entities (e.g. applications, processes etc.) wherein each entity comprises an associated entity profile having associated profile data. The system comprises: a focus component for detecting focus of a first entity and an intercept component for intercepting the input stream having input data, before the input stream is input to the focused first entity. A match component matches the input data with first profile data of a first entity profile associated with the focused first entity. In response to the input data not matching the first profile data, the match component matches the input data with second profile data of a second entity profile associated with a second entity. In response to the input data matching the second profile data, the input stream is transmitted to the second entity.

A method and system for collaborative editing of a document by an author of the document and reviewers. Program code receives from the author an identification of selected portions of the document and receives from the author: comments created by the author and an identification of at least one reviewer to which each comment is directed. The selected portions and the comments are associated with each other on a one-to-one basis. Each comment pertains to content of the selected portion that each comment is associated with. The program code parses the received comments, and utilizes the identification of the at least one reviewer to which each comment is directed, to generate a list of comments specifying for each comment the at least one reviewer to which each comment is directed. The program code makes available to each reviewer the comments on the list of comments directed to each reviewer.
