Embodiment Construction
[0020] The real-time enterprise service bus system of the present invention supports three types of QoS-level services: the first type of service has a small delay and jitter, has a fixed transmission rate, belongs to real-time services, and has a high priority; the second type of service has a variable rate, Compared with the first type of business, the delay and jitter requirements are lower, and the minimum bandwidth guarantee is required. It is a non-real-time business with a medium priority; the third type of business has basically no requirements for delay and jitter, and the service can be suspended when the system is overloaded. Non-real-time, low priority.
[0021] A JBI-compliant binding component contains two semantics. One is the priority Priority, the value is high, middle or low. The second is the business time constraint timeoutMS, in milliseconds. When the service queuing time exceeds the constraint, the service will return a timeout error.

The invention discloses a real-time enterprise service bus system. The system comprises four assemblies conforming to the JBI standard. The four assemblies comprise the binding assembly, the service engine assembly, the transmission channel assembly and the normalized message router assembly. According to the requirements for response time of services at different QoS levels, a QoS priority drive system is used for processing a bandwidth allocation strategy, real-time response processing of services with high QoS priorities is guaranteed, and the requirements for service quality of hard real-time services are met. The real-time enterprise service bus system can solve the problems that a system is congested and the service quality is lowered when the services at different QoS levels contend for limited service bus processing bandwidth resources due to the fact that a traditional enterprise service bus does not have real-time scheduling capacity. Service quality reduction caused by service congestion is reduced through bandwidth resource scheduling, and the total throughout rate of the enterprise service bus system is increased.
Description
technical field [0001] The invention relates to the technical field of computer information management, in particular to an enterprise service bus system, and in particular to a method for asynchronous transaction processing and resource scheduling within the system. Background technique [0002] Enterprise Service Bus (ESB) is a data exchange platform for collecting, integrating and exchanging business data of heterogeneous information systems, and providing support for business collaboration between information systems. Compared with the traditional SOA architecture, the ESB solution is more concise. ESB provides event-driven and document-oriented processing modes, supports content-based routing and filtering, and has the ability to transmit complex data. However, as a centralized SOA solution, the core problem of ESB is its performance bottleneck. The service processing model of ESB is essentially a queuing network performance model. When multiple services with different...
