Structured document communication system between multiple processes

Abstract

The invention relates to a structured document communication system between multiple processes, comprising: structured document processing equipment, which is used to generate structured documents and carry out dynamic operations on the documents, generation of mapping relationships of the communication information, and update the structured documents, wherein preconditions of the functions realizing are successful establishment of shared memory by a memory and privilege management equipment and successful authorization of communication processes; the memory and the privilege management equipment, which are used to establish and manage the shared memory, and manage operation application authority of the processes; a communication terminal, which is used to send communication information of the node and receive communication information from other nodes Which preconditions of the functions realizing are successful establishment of the documents by the structured document processing equipment and finish of operating the document, and part of the functions of the communication terminal is further activated by accidents generated by the structured document processing equipment. The system in the invention has versatility that enables multiple processes to realize priority communication of the most important data, rapid multiple data communication and a characteristic of data structuralization in a communication process.

Description

technical field [0001] The invention relates to the field of computer technology and network communication, in particular to a multi-process communication system. Background technique [0002] In the process of Windows application program development, there will be information exchange between multiple processes in different systems or different processes in the same system. These processes may be distributed on the same node of the network, or may be distributed on multiple different nodes. In the face of a small amount of data without a special structure, the existing technology can solve it very well. Once the amount of data is complicated and requires a special organizational structure, it is often necessary to end the huge and expensive resources such as local data files or data. This undoubtedly increases the development cost; and when the internal data structure of a program changes, the communication interface with other processes that may lead to its association ch...

Problems solved by technology

Among the above methods, the shared memory method supports the communication of large amounts of data among multiple processes best, and has better security, but the existing traditional shared memory method access method is based on the actual physical address plus byte access, cannot communicate according to the original structure of the data

For multi-process communication between different nodes in the communication network, the Sockets method is often used, but the data format for communication is relatively single, and cannot support structured multi-format information, and the communication interface will also vary with the data structure of other processes. Varies with changes, poor scalability
