Siena (Scalable Internet Event
Notification Architecture) is a research project aimed
at designing and constructing a generic scalable event
notification service. For full details on the Siena
project follow this link. This page
contains source and binary packages as well as user documentation for
the implementation of Siena. Other Siena software is available
from the Siena contrib page.

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.
