Zusammenfassung: | The invention relates to a message broker for managing subscription requests in a multicast messaging system. The messaging system comprises a plurality of publishers publishing information to the broker and a plurality of subscribers subscribing to information received from one or more publishers. The broker is able to receive a subscription request pointing to topic information in which the requesting subscriber is interested, the topic information defining a specific topic within a topic hierarchy. The broker is able to parse the request to determine if the request includes a wildcard and if the request does include a wildcard, the broker instructs the requesting subscriber to listen on a multicast address associated with the topic in the topic hierarchy which precedes the wildcard. |
