Problems solved by technology

[0002] In a distributed system environment, a variety of networks are involved in the construction of the system, and the message transmission between systems cannot be carried out directly, and message forwarding and message conversion are required. Due to the diversity of network resources, there is a lack of a method for message forwarding and message conversion. In a unified way, the developed software with message forwarding and message conversion functions has poor portability and low reusability

Embodiment Construction

[0018] Describe technical scheme of the present invention in detail below:

[0019] 1. When an application program uses this method to exchange messages, it must first determine the configuration data, and specify the network protocol, network connection parameters, and message routing information used to establish a connection between the routing service and the application through the configuration data. Network protocols refer to specific protocol types such as JMS, TCP, and DDS; network connection parameters refer to the parameters required to establish a connection, for example, when the underlying network is Ethernet, an IP address and port are required to establish a connection; message routing information includes message names , message type name, source, and destination attributes.

[0020] 2. Routing service requires two functional supports for message routing, including message conversion and message forwarding:

[0021] 2.1. Message conversion. Different network...

Abstract

The invention belongs to the computer system software professional technology field and provides a routing service implementation method based on publishing and subscription. In a distributed networkenvironment, various kinds of network protocols are related and the different protocols can not directly carry out communication. In the invention, based on a publishing and subscription mechanism, arouting service is designed, message forwarding is performed based on the publishing and subscription mechanism, message conversion among the different protocols can be realized, and an effective extension mechanism is provided to support the different protocols. A message interaction problem among cross-network systems is solved, the development efficiency of application software is effectively increased, and a new and old system compatibility problem during a software system upgrading process is reduced. Based on the message routing mechanism of publishing and subscription, effective data forwarding is realized; the message conversion among the different protocols is achieved; and a flexible and extensible protocol adaptation model can support various kinds of network transmission protocols.

Description

technical field [0001] The invention belongs to the professional technical field of computer system software, and provides a method for implementing routing services based on publish and subscribe. Background technique [0002] In a distributed system environment, a variety of networks are involved in the construction of the system, and the message transmission between systems cannot be carried out directly, and message forwarding and message conversion are required. Due to the diversity of network resources, there is a lack of a method for message forwarding and message conversion. In a unified way, the developed software with message forwarding and message conversion functions has poor portability and low reusability. Accordingly, a method for implementing routing services based on publish and subscribe is proposed, which provides a message routing mechanism based on publish and subscribe; realizes message conversion between different protocols; has a flexible and scalable...
