Overlay broker networks are an important part of an event-based middleware. This paper investigates the requirements of overlay broker networks and argues that using peer-to-peer techniques for their creation and the content-based routing of events has many advantages. They support their claims with an experimental evaluation of Hermes, an event-based middleware architecture that uses a peer-to-peer routing substrate, in comparison with a standard publish/ subscribe system that has a simple, predefined overlay topology. The results reveal that Hermes has better routing efficiency and keeps less routing state at the event brokers.
