Universal Messaging is a Message Orientated Middleware product that guarantees message delivery across public, private and wireless infrastructures. Universal Messaging has been built from the ground up to overcome the challenges of delivering data across different networks. It provides its guaranteed messaging functionality without the use of a web server or modifications to firewall policy.

Universal Messaging design supports both broker-based and brokerless communication, and thus comprises client and server components.

The standard UM "broker-based" client component can be subdivided into messaging clients, comet clients and management clients. The server component has specific design features to support each of these classifications of client as well as Scheduling and Triggers, Plugins, Federation, Clustering and Low Latency IO.

The Universal Messaging realm server is a heavily optimized Java process capable of delivering high throughput of data to large numbers of clients while ensuring latencies are kept to a minimum. In addition to supporting the client types described below the Universal Messaging realm server has a number of built in features to ensure its flexibility and performance remains at the highest levels.

Universal Messaging supports 3 client types:

Each client type is been developed using open protocols with specific attention paid to performance and external deployment. Each client type has been specifically designed to transparently pass through firewalls and other security infrastructure while providing its own inherent security features.

Universal Messaging messaging clients support synchronous and asynchronous middleware models. Publish Subscribe, Queues and Peer to Peer functionality is all supported and can be used independently or in combination with each other. Universal Messaging messaging clients can be developed in a wide range of languages on a wide range of platforms. Java, C# and C++ over Win32, Solaris and Linux are all supported. Mobile devices and Web technologies such as Silverlight all exist as native messaging clients.

In addition to our native binary wire protocol Universal Messaging also supports text based delivery for languages that do not support binary data. Used in conjunction with Universal Messaging server plug-in technology, Comet and Long Polling clients use HTTP and persistent connections to deliver asynchronous Publish Subscribe, and Peer to Peer functionality to clients. JavaScript clients can also use WebSocket as a delivery approach although this is not yet sufficiently supported in users' browsers to warrant a reliance on it over Comet/long Polling.

Universal Messaging provides a very extensive and sophisticated management API written in Java. Management clients can construct resources (Channels, ACL's queues etc.) and query management data (throughput, cluster state, numbers of connections etc.) directly from Universal Messaging realm servers.

Universal Messaging offers, in addition to its standard full-featured client-server API, an extremely lightweight client-client communication API known as the Brokerless API (currently available for Java only).
