Problems solved by technology

In the past multi-processor development and debugging, the software and hardware are closely integrated, the supporting software functions are simple, the system is not open enough, and the communication is not flexible enough, etc., which eventually lead to limited system functions and performance, and increased development cycle and development costs.

Embodiment Construction

[0029] The message middleware supports three physical communication links (SRIO, Gigabit Ethernet, and shared memory). The following uses SRIO links as an example to describe the three communication methods of point-to-point, one-to-many multicast and many-to-one gathering , the three communication modes under the Gigabit Ethernet and the shared memory link are similar and will not be repeated here.

[0030] The point-to-point data transmission process is initiated by the receiver, and the receiver first sends a SRIO short message to the sender, the content of which is the SRIO device ID number of the receiver, the receiving first address, and the length of the received data. After successfully receiving the short message, the sender can send data of a specified length to the receiving first address of the receiver according to the content of the message. The data length is the minimum value of the received data length and the sent data length. After the data is sent, the rece...

Abstract

The invention provides a message-oriented middleware system between distributed application programs and a method of message passing between distributed application programs. The system comprises a sender, a receiver, a group and an interface function. The system is characterized in that nodes in the group include a main member and one or more than one auxiliary member; the main member establishes the group by using a globally unique name and sets that the group includes N members including the main member when establishing the group; each auxiliary member joins a certain established group by using a unique name and determines a non-repeated serial number for itself during joining.

Description

technical field [0001] The invention relates to network communication technology, in particular to a message delivery method and a message middleware system between distributed application systems. Background technique [0002] Message oriented middleware refers to middleware that supports and guarantees synchronous / asynchronous message sending and receiving between distributed applications. Message is the basic information unit for data exchange between distributed applications, and the communication interface between distributed applications is provided by message middleware. Specifically, message middleware is data communication middleware between processes or threads, providing unified services for data transmission between tasks (processes or threads), regardless of the physical location of the task or the communication carrier. [0003] At present, message middleware has been widely used in various distributed application systems. For example, in the parallel signal ...
