1. Converged Load Balancer.
2. Administration and Monitoring support for the SIP Servlet Container.

4. Support for custom application router deployment.
5. Extensive load testing.

About SailFin
Project SailFin is based on robust and scalable SIP servlets technology on top of a deployment-quality, Java EE-based GlassFish. We are working towards achieving JSR 289 compatibility, adding high- availability and clustering features, and integrating with existing GlassFish services.

JSR 289 updates the SIP Servlets API and defines a standard application programming model to mix SIP Servlets and Java EE components. Java EE services, such as web services, persistence, security, and transactions, enable faster development of smarter communications-enabled applications.
