A Low Cost and Resilient Message Queuing Middleware

Message Queuing Middlewares (MQMs) are gaining more and more attention in large enterprises for building highly available asynchronous messaging systems and for integrating heterogeneous applications. However, currently available MQMs consider underlying networks as static. Therefore, in case of node failures or a disaster, either they have to suffer long term service loss or they need to install a lot of extra resources to ensure that no such failures cause any service loss. They also require large administrative overhead as the network is managed manually. Besides, as store-and-forward method is used, reliable delivery of messages suffers much network delay and generates large amount of traffics.
