Abstract :
In e-science environment researchers pay great attention to some events, such as the current states of computing services which related with their works and some new computing services. So we adopt the publish/subscribe system in e-science environment to satisfy the requirement. Broker management in publish/subscribe system is important because it affects directly the stability and robustness of the system. For example, the breakdown of broker may lead to system fault and the imbalance among brokers may result in broker failure. Broker management could be solved by a central broker, but it may lead to single-point bottleneck. So in our paper we propose a distributed broker management. We firstly introduce our publish/subscribe system which takes the responsibility for informing researchers of concerned special events. Then we focus on distributed broker management. Finally it shows comparisons and simulations to evaluate the performance of the publish/subscribe system.
