Overview

This implementation of Siena consists of two classes of components:

• Siena servers (or routers), and
• client-level interfaces (or API).

The current prototype includes three variants of servers and two variants of interfaces. The interfaces are for Java and C++. The Java language interface also works as a server, and implements both a hierarchical architecture and a general network architecture. The other server, which at this point should be considered obsolete, implements a peer-to-peer architecture and is programmed in C++. Notice that the two server and API implementations are not mutually compatible.

In summary, there are two implementations that, for lack of better terms, I will call Current and Old respectively. These include the following components:

Current Version

a Siena router capable of supporting a general network topology plus an application programming interface for Java. This implementation also includes the previous Siena router which is based on a hierarchical network.

Old Version

a peer-to-peer server implemented in C++ and a C++ API.

Unless you intend to experiment with the "Old" implementation, you should download and use the "Current" version.
