Description

基于可靠协议兴趣代理的分布式发布/订阅系统及方法 Interest-based distributed publishing reliable protocol proxy / subscribe system and method

技术领域 FIELD

[0001]本发明涉及数据交互系统,特别是涉及一种基于可靠协议兴趣代理的分布式发布/订阅系统及方法。 [0001] The present invention relates to a data exchange system, particularly to a publish / subscribe system and method based on a reliable protocol of Distributed interest.

背景技术 Background technique

[0002]分布式数据交换中的发布/订阅关系一般基于组播或广播协议建立,发布方和订阅方的对应关系由网络协议作为主体承担,分布式软件不管理、不维护发布/订阅关系。 [0002] distributed data exchange in the publish / subscribe relationship generally based on multicast or broadcast protocol to establish the correspondence between the publisher and the subscriber shall be borne by the body as a network protocol, a distributed management software does not maintain publish / subscribe relationship. 因此建立的分布式发布/订阅数据交换特别依赖组播或广播网络环境。 Therefore, the establishment of distributed publish / subscribe data exchange is particularly dependent on multicast or broadcast network environment. 目前,由于网络安全、 数据安全以及分布式规模扩大等因素日益突出,网络条件再难以满足分布式数据交换的组播或广播环境。 At present, due to network security, data security, and distributed scale and other factors have become increasingly prominent, network conditions made it difficult to meet environmental multicast or broadcast distributed data exchange. 可靠协议,如TCP,具有很强的通用性,是目前互联网络普遍使用的协议规范。 Reliable protocol, such as TCP, are highly versatile, it is the Internet protocol specification commonly used. 但是,由于可靠协议一般是单播协议,极少的分布式发布/订阅方法基于此此类协议。 However, the agreement is generally reliable unicast protocol, very few of distributed publish / subscribe such agreements based on this method. 而基于可靠协议的分布式发布/订阅方法,基本限于特定网络条件、特定数据类型。 And a reliable protocol based on distributed publish / subscribe approach is essentially limited to particular network conditions, the specific data type. 目前,分布式数据交换的网络环境难于保证组播或广播条件,并日益注重网络和数据的安全性,同时, 分布式数据交换趋于大规模多样数据的方向发展。 Currently, distributed data exchange network environment is difficult to secure multicast or broadcast condition and is increasingly focusing on network and data security, at the same time, the direction of large-scale distributed data exchange tends to diverse data development.

[0003]因此,需要提供一种通用适用的基于可靠协议的分布式发布/订阅方法,以满足现代互联网对于分布式数据交换的需求。 [0003] Therefore, it is necessary to provide a common application of a reliable protocol based on distributed publish / subscribe methods to meet the needs of the modern Internet for distributed data exchange.
