An advertisement and matching subscription are tightly coupled to activate a single publication routing path in content-based publish/subscribe systems. Due to this tight coupling, instantaneous updates in routing tables are required to generate alternative paths for dynamic routing. This poses serious challenges in offering scalable and robust dynamic routing in cyclic overlays when network conditions like link congestion is detected. We propose, OctopiA, a distributed publish/subscribe system… CONTINUE READING

Key Quantitative Results

  • Experiments on a cluster testbed with real world data show that OctopiA reduces the number of saved advertisements in routing tables by 93%, subscription broadcast delay by 33%, static and dynamic publication delivery delays by 25% and 54%, respectively.
