castixx™ is a 100% java middleware. The Group-Communication Protocol offers a communication platform for event-driven applications. Castixx is JMS-compliant and can be integrated into systems supporting JMS.
Among other things Castixx provides applications for content delivery systems, groupware, distribution of financial news and rates, fault-tolerant client server systems, and multimedia applications.
Castixx uses multicast channels. The applications communicate by push/pull/subscribe communication paradigms.
Communicating applications possibly running on different machines are interconnected by abstract channels without loosing the castixx-URL addresses.
Castixx applications do not depend on server processes (no single point of failure) and thus provide a fault-tolerant runtime environment. The following services can be made available depending on the specific application:

• Reliable (guaranteed delivery) and unreliable multicast
• Reliable und unreliable point-to-point UDP interconnections
• Troubleshooting/debugging
