Inter-process structured document communication method

Abstract

The invention relates to an inter-process structured document communication method. The method comprises: searching a shared memory zone of local communication nodes by a communication process, submitting the application for creating a shared memory for communication and creating a structured document object if the zone does not exist, registering the content needed to be communicated in the process after the application is responded, and serializing the document; storing the serialized document into the shared memory zone, carrying out application for operation, and waiting for response till authorization is acquired; after being authorized, deserializing the acquired structured document object in order to acquire document content, and reading and writing the structured document and saving the document according to a demand; then serializing the modified structured document, and releasing operation authority; and submitting network communication application by the communication process to realize inter-process structured document communication. The method of the invention is used for multi-process communication in one node or between different nodes, has versatility, and can guarantee the realization of priority communication of the most important data and rapid communication of mass data as well as data structuralization in the multi-process communication process.

Description

technical field [0001] The invention relates to the field of computer technology and network communication, in particular to a method for multi-process communication. 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 associatio...

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
