摘要： 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.

摘要： A transmission method adjusts the size of aggregated packets based at least on the congestion of a transmitting network device. The adjusting comprises includes aggregating at least two small messages, received from an upper layer, into a packet, providing the packet to a pending queue, passing packets to a network device and selecting packets from the pending queue or the buffer depending on whether or not said pending queue is empty.
