Abstract

The invention discloses a reliable protocol interest agent based distributed publishing / subscription system and method. The reliable protocol interest agent based distributed publishing / subscription system comprises a publisher unit for establishing a distributed publishing / subscription data exchange publisher, a publisher management unit for establishing a subscription agent corresponding to the publisher according to the publisher and storing the interest of the publisher and the subscription agent corresponding to the publisher, a data channel module for establishing a distributed data exchange channel for the publisher and a subscriber, a subscriber management unit for establishing a publishing agent corresponding to the subscriber according to the subscriber and storing the interest of the subscriber and the publishing agent corresponding to the subscriber, and a subscriber unit for establishing a distributed publishing / subscription data exchange subscriber. By means of the technical scheme, multicasting or broadcasting and other special network condition limitations are broken through, and the network safety and data reliability are improved. Data scale is not limited based on a interest agent mode, and the reliable protocol interest agent based distributed publishing / subscription system and method are not limited to specific data contents and can effectively establish large-scale universal publishing / subscription relation.

Description

technical field [0001] The invention relates to a data interaction system, in particular to a distributed publishing / subscribing system and method based on reliable protocol interest proxy. Background technique [0002] The publish / subscribe relationship in distributed data exchange is generally established based on multicast or broadcast protocols. The corresponding relationship between publishers and subscribers is assumed by the network protocol as the main body. Distributed software does not manage or maintain the publish / subscribe relationship. The distributed publish / subscribe data exchange thus established is particularly dependent on a multicast or broadcast network environment. At present, due to the increasingly prominent factors such as network security, data security, and distributed scale expansion, network conditions are no longer suitable for the multicast or broadcast environment of distributed data exchange. Reliable protocols, such as TCP, have strong vers...
