Research of Pub/Sub System Routing Based on Subscription Union-cover
He Huang · Computer Knowledge and Technology · 2009
Pub/Sub system has been an important method for Internet computing. It has the characteristics of asynchronization,anonymity,many-to-many and loosely coupled communication. Matching and routing are the core technology of Pub/Sub system,and the Subscription Cover Based Routing (SCBR) has been applied in many cases. The paper revealed the developed routing tables in pub/Sub system ,and the Subscription Union-cover Based Routing (SUCBR) is developed,and the specific alforithm for acyclic Pub/Sub system is given. The results of experiments applying SCBR and SUCBR suggest that in many cases SUCBR is more effective.
