Distributed publish/subscribe system and method based on reliable protocol interest proxy

Abstract

The invention discloses a distributed publishing / subscribing system based on a reliable protocol interest proxy. The system includes a publishing unit, which is used to construct a publishing side for distributed publishing / subscribing data exchange; The corresponding subscription agent stores the interests of the publisher and the corresponding subscription agent; the data channel module is used to establish a data channel for distributed data exchange between the publisher and the subscriber; the subscriber management unit is used to The party creates its corresponding publishing agent, and stores the interest of the subscriber and its corresponding publishing agent; the subscriber unit is used to construct the subscriber of the distributed publish / subscribe data exchange. The technical scheme of the present invention breaks through the limitations of special network conditions such as multicast or broadcast, and improves network security and data reliability; the interest-based proxy method does not limit the data scale or specific data content, and can effectively establish large-scale Generic publish / subscribe relationship.

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...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a distributed publishing / subscribing method based on a reliable protocol, which solves the limitation of the network environment caused by factors such as network security, data security, and distributed scale expansion, which lead to a problem based on multicast or broadcast protocols. Publish / subscribe software fails, resulting in difficulty in distributed data interaction
