為了解決消息中間件中的性能瓶頸問題和實現(xiàn)其可靠性的提高，研究并開發(fā)了支持多服務(wù)的消息中間件，提供單個節(jié)點無法提供的性能和可靠性保障。消息集群設(shè)計過程中涉及的主要內(nèi)容包括：消息中間件特點分析、消息集群特征總結(jié)、消息集群整體結(jié)構(gòu)的研究和設(shè)計以及負載均衡、負載遷移、故障恢復(fù)這三項關(guān)鍵技術(shù)的設(shè)計與實現(xiàn)。
關(guān)鍵詞: 消息中間件，集群，負載均衡，負載遷移，故障恢復(fù)
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
