Abstract

We describe an implementation based on the WS-Notification (WSN) specification for Publish/Subscribe communication which provides a distributed, content-based notification service. The implementation is based on a distributed hashtable (DHT) built on a structured overlay of peer nodes. The entire system acts as a notification broker, so that notification producers and consumers that make use of the network can achieve loosely-coupled communication with a decentralized, scalable service. We develop and evaluate self-optimizing behavior built to reduce notification traffic within the network.
