Research on Aggregate-Type Network Communication System Based on Information Sharing
Yue Li, Zuhua Peng, Chao Xu · 2015
Under the Web 2.0 environment, to break isolation between sites and share information is the development trend of network media as well as the objective needs of netizens.Some network operators have researched on this, however, the four traditional communication programs, server agent, dynamic creation of script, segment identifier communication and Flash technology, have low efficiency, transmission quality and security.Therefore, based on cross-text communication technology, this paper builds an aggregate-type network communication system which depends on information sharing to improve the efficiency, quality and security of information aggregation between sites and provide netizens with more convenient service of information aggregation. Aggregate-type Cross-domain Communication Program DesignThe aggregate-type cross-domain communication program system in this paper first treats different websites or sites as individual trust domain, next encapsulates them to internal components which have interactive access and transmission ability, and then uses the new cross-text communication technology of HTML5 to achieve the communication activities between components.In this way, it can meet the requirements of convenient, effective and safe cross-domain information visiting.Specifically speaking, the latest version HTML5, developing from HTML, is added to another new cross-text communication mechanism or cross-text communication technology to meet the requirements of cross-domain information visiting between sites.It calls PostMessage in the iframes or specific window of message requirement transmitter, while sets up a event hander in receiving end to receive the message requirement signals to achieve information dock.The steps are as follows: first, call PostMessage in the iframes or specific window of information to send metadata requirement message of data, origin and source; next, assign the receiver or sender; last, add a event listener for message event in the receiving window of metadata requirement message to extract and return data.This method can guarantee accurate aggregated data and meet requirement of pre-fetch message aggregation.This method can guarantee accurate aggregated data and meet requirement of pre-fetch message aggregation. The Safe cross-domain Communication System Based on Information SharingAs shown in Figure 2-1, this safe cross-domain communication system consists of domain encapsulation module, inter-domain communication module and fine-grained object sharing module.These modules are the basic structures of this system. Domain encapsulation moduleTrust domain, also named trust site, refers to credible IP address or DNS website in aggregate-type network communication mode, security system is added to DNS domain.The components, mainly supplied by the third-party, are indentified as encapsulation of metadata in the same trust domain or trust site.They are logically independent, and have individual input and International Conference on Manufacturing Science and Engineering (ICMSE 2015)
