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
