Abstract

The present invention relates to a publish-subscribe system (Pub / Sub) in a computer network environment, and more specifically, the present invention particularly relates to a method and a system for orderly obtaining messages of a distributed publish-subscribe system. The present invention provides a method for sequentially acquiring multiple messages based on a specific topic in a distributed subscription publishing system, the distributed subscription publishing system includes at least one message transfer server, and the method includes: determining the message to be obtained The sorting of multiple messages; record the message relay servers where the multiple messages are respectively located in the message relay server sequence information, and the message relay server sorting in the message relay server sequence information corresponds to the determined multiple message sorting ; and using the sequence information of the message relay server to sequentially obtain the plurality of messages from the corresponding message relay server.

Description

technical field [0001] The present invention relates to a publish-subscribe system (Pub / Sub) in a computer network environment, and more specifically, the present invention particularly relates to a method and a system for orderly obtaining messages in a publish-subscribe system in a distributed computer network environment. Background technique [0002] At present, the news publishing and subscription system (Pub / Sub) has become one of the important ways for users to obtain network information in the era of computer networks. In a publish / subscribe system, many subscribers select interested news sources according to their own needs. Once a publisher publishes a message, the message is picked up by subscribers. [0003] With the widespread application of the distributed computer network environment, the current publish / subscribe system mainly adopts two modes: the mode of actively pushing messages and the mode of actively obtaining messages by subscribers. In the mode of a...
