| Talk Title: | Robust Content-based Routing in Cyclic Publish/Subscribe Systems |
| Slides: | 1-5.ppt |
| Abstract: | Distributed publish/subscribe model provides the semantics and an efficient method for large-scale dissemination of data from publishers to subscribers. In these systems, publications are routed through overlay networks formed by the interconnection of content-based routers. While a tree-based overlay simplifies the routing algorithms, such an approach is unable to efficiently handle network partitioning resulted in face of router or link failures. In this research, we focus on content-based routing in cyclic publish/subscribe overlay networks to improve robustness and failure resiliency of the system. Our approach is based on efficiently detecting and maintaining overlay cycles at publish/subscribe routers. In face of failures, the affected publication flows are automatically re-established through alternative paths. Moreover, our preliminary results show that by exploiting cycle information in a failure-free operation of the system significant improvement in publication delivery delay is achieved. |
