Sun GlassFish Communications Server

Open Source: GlassFish Communications Server builds on Sun's open-source tradition and foundations including Java and Java EE initiatives. This model provides companies with easy means to test a product before making an investment. It also offers the resources of the worldwide community of Java developers, including a network of people creating applications for the platform as well as a large talent pool of expertise.

Price/Performance: GlassFish Communications Server is a mixture of rich features and highly competitive pricing. Sun offers flexible pricing structures in the form of subscriptions or perpetual licenses; this significantly reduces the barrier to entry for customers looking to develop cutting-edge services while keeping costs in control.

Converged Communications: GlassFish Communications Server is a converged communications server that brings together the capabilities of Java EE and SIP. As customers integrate IP-based communications into existing applications or create consumer-oriented applications providing multimedia communications such as Facebook or MySpace, an infrastructure that simplifies development and deployment process is critical. GlassFish Communications Server 1.5 helps to provide a foundation that is optimized for both enterprise and telecommunications environments and is ideally suited for creating converged communications applications.

• Compliant with SIP RFCs and SIP Servlet 1.1 specification.
• High availability through in-memory replication, clustering, and easy administration
• Load balancer: Integrated SIP and HTTP load balancing
• Security: Integrated SIP security with Java EE security
• Tooling: Support for NetBeans and Eclipse with SIP annotations and SIP servlet wizard
• Multi-platform support including SUSE, Red Hat, Solaris (Sparc & X86), and Windows
• Multi-home and IPV6/Dual Stack support
• Overload protection
• High performance, high throughput, and low latency
• Diameter support for Ro, Rf and Sh interfaces
• Plus all the key GlassFish Enterprise Server features

• Standards. Support for standards are critical to ensure interoperability and integratability. GlassFish Communications Server 2.0 is the first open-source SIP application server with commercial support. It is compliant with JSR-289and SIP Servlet 1.0 & 1.1. Additionally, GlassFish Communications Server 2.0 is built on GlassFish Enterprise Application Server, the leading open-source application server that is based on Java EE 5 and supports interoperability with Microsoft Web services framework.
• Open Source. GlassFish Communications Server is freely available, has a large community of partner applications, and is part of the GlassFish community.
• Performance. GlassFish Communications Server is built on Sun GlassFish Enterprise Application Server, an industry-leading, Java-compliant container that established industry benchmark records. GlassFish Enterprise Application Server leads in overall price-performance compared to other application servers. Additionally, GlassFish Communications Server is built on a high-performance Web services framework (Web Services Interoperability Technology).
• Simplified Development. GlassFish Communications Server offers ease of development with support for integrated SIP application development through NetBeans. By leveraging this environment, developers can easily combine the capabilities of the core Java EE platform with the new SIP features to create converged applications. Support for features like SIP annotations and integrated runtime reduces the time to develop and deploy applications.
• High Availability. GlassFish Communications Server provides highly scalable, reliable telco-grade in-memory persistence for SIP and converged applications. It also provides several other HA features including the abilities to regulate traffic based on CPU or memory load and provision to upgrade the application/application server using rolling upgrade without any downtime.
• Converged Load Balancer. The integrated converged load balancer supports many configurable policies (such as dispatching requests) by applying consistent hashing on selected message headers.
• Robustness. Working with a leading network equipment provider like Ericsson and with an open-source community in a transparent manner has allowed Sun to maintain a high-quality implementation that combines the strengths of open-source and commercial implementations in developing critical telecom infrastructures.
• Diameter. GlassFish Communications Server provides a diameter client that supports Ro, Rf and Sh interfaces, it also provides a reliable and scalable authentication, authorization and accounting environment and makes it easy communication for Telco applications to communicate with other billing server solutions.
