Embodiment Construction

[0036] In order to make the purpose of the present invention, technical solutions and advantages clearer, at first the terms in the implementation of the present invention are explained:

[0037] The message offset is the difference between the position where the message is currently read in the message queue and the initial position in the queue;

[0038] The message queue is a container (data sequence) for saving messages during message transmission;

[0039] Next, the present invention will be described in detail with reference to the drawings and specific embodiments.

[0040] figure 2 It is a message transmission structure diagram based on a star topology in the embodiment of the present invention, and constructs a central node C and non-central nodes A, B, and D according to the characteristics of a star topology; wherein, middleware is respectively configured in each non-center module, the middleware module includes the following sub-modules, which are middleware mod...

Abstract

The invention discloses a star topology framework-based message transmission method. The method comprises the following steps of: 1) setting a source and a destination of message transfer; 2) constructing and configuring a middleware module between a center node and non-center nodes according to the quantity of the non-center nodes, wherein the middleware module is sued for pulling synchronous data from a source node and transmitting the synchronous data to an objective node according to appointed transmission direction; 3) starting each middleware sub-module, and determining the non-center nodes with data synchronization requirement according to configured content in the step 2); 4) obtaining messages in a consumer message queue, namely, a second message queue, by a message pull sub-module of the middleware module; 5) comparing a message offset of the second message queue and a message offset of a first message queue; 6) submitting the message offset of the consumer message queue to a producer by the middleware module through the center node; and 7) combing a message offset of an own queue and the message offset of the consumer message queue by the producer, and transmitting newly added data to the center node.

Description

technical field [0001] The invention belongs to the field of data transmission in software technology, and in particular relates to a message transmission method based on star topology architecture. Background technique [0002] Nowadays, more and more enterprises choose to build distributed systems due to the prominent advantages of distributed environment, but they undoubtedly also face data management problems caused by data integration and system integration, especially distributed data call has attracted much attention; subsequently, Distributed object invocation technologies, such as RPC middleware technologies such as ORBA, DCOM, and RMI, emerged as the times require. RPC refers to middleware based on Remote Procedure Call (RPC), which allows procedures in one application to call procedures in a remote application as if they were local calls. This middleware implements a chaining mechanism that looks up remote procedures and enables callers to use these procedures in...
