Tycho Architecture

Tycho consists of the following concepts:

1. Mediators that allow Producers and Consumers to discover each other and establish remote communications,
2. Consumers which typically subscribe to receive information or events from Producers,
3. Producers, which gather and publish information for Consumers.

In Tycho, Producers or Consumers can publish their existence in a directory service known as the Virtual Registry (VR). A client uses the VR to locate other clients, which will act as a source or sink for the data they are interested in. The VR is a distributed service provided by a network of Mediators. When possible, clients communicate directly, however for clients that do not have direct access to the Internet, the Mediator provides wide-area connectivity acting as a gateway or proxy into a localised Tycho installation.
