中文摘要: 首先介绍应用服务器EBAS(EB Application Server)的概况并分析其存在的弊病，然后据此设计消息分发组件，详细介绍了消息分发组件的结构和处理逻辑，包括消息分组件与外部实体的消息交互方法、维护外部实体的状态的准则、区别外部实体是重连还是重启的策略。添加消息分发组件的EBAS可靠性更高，支持在线无损升级，更加适合大容量、高并发的业务模型。
Abstract:This paper introduces the application server EBAS (EB Application Server) and makes an analysis of the shortcomings of its existence. Then, it designs a module of distributing the message components accordingly, to achieve distribution and load sharing of messages. It expounds the structure of news distribution and the processing logic, including the message distribution components interaction with external entities, the rules to safeguard the state guidelines for external entities and the strategy to distinguish restart from reconnect of external entities. EBAS with message distribution component is more reliable, supportive of online non-destructive upgrade and more suitable for the service model with large capacity and high concurrency.
