為了解決消息中間件中的性能瓶頸問題和實現其可靠性的提高，研究并開發了支持多服務的消息中間件，提供單個節點無法提供的性能和可靠性保障。消息集群設計過程中涉及的主要內容包括：消息中間件特點分析、消息集群特征總結、消息集群整體結構的研究和設計以及負載均衡、負載遷移、故障恢復這三項關鍵技術的設計與實現。
關鍵詞: 消息中間件，集群，負載均衡，負載遷移，故障恢復
Abstract: To solve the performance bottleneck of Message Oriented Middleware (MOM) and prove its reliability， we design and develop a new MOM that can support multi-services and offer performance and reliability assurance which single MOM can not afford. The main contents involved in the design process of message cluster include: the characteristics analysis of MOM， the sum-up of message cluster’s characteristics， the investigation and design of message cluster’s entire structure， the design and realization of load balancing， load transfer and failover these three key techniques.
Key words: Message Oriented Middleware (MOM)， cluster， load balancing， load transfer， failover
