What is a Communications Platform ? Enable creation, deployment and management of services and applications that integrate voice, video and data across a range of IP and communications network by multiple devices “Any content” + “Any network” + “Any device” = Convergence Mobicents Communications Platform drives Convergence by bringing to you the infrastructure to build your next generation applications Communications platform enable the creation, deployment and management of services and applications that integrate voice, video and data and function seamlessly across a range of IP and communications network that can be accessed by computers, hand sets and other network enabled devices In the telecommunications industry, the concept of “any content” on “any network” that can be connected to “any device” is referred to as Convergence Mobicents Communications Platform drives Convergence by bringing to you the infrastructure to build your next generation applications 2

JSLEE - Concepts Asynchronous support & Event oriented Let's starts with Mobicents JAIN SLEE. First what is JSLEE ? It is a Specification that has been Defined by the JCP and currently the 1.1 version (JSR 240) has just been released What does SLEE stands for ? It stands for Service Logic Execution Environment which means a High throughput, low latency event processing which are well know concepts in the telco industry Built-in support for HA and scalability through State replication, Transactional semantics and Exception handling. Modularised, component and transaction based Execution Environment providing a framework for portable components JSLEE features Asynchronous support & is Event oriented through an Elaborated event distribution mechanism (with priority)‏ and the Mapping of events and method invocation on components called SBBs that are composing a JSLEE service Creates components instances in response to initial events Independent of underlying networks through Resource Adaptors. Ressource Adaptors are wrappers for protocols events in order to fire any protocol event received from the network into JSLEE in a standardized manner to be able to have portbale applications This is really meant to be a High performing platform for event driven applications SLEE is complementary to Java EE Specification Defined by the JCP, v1.1 (JSR 240) just released SLEE = Service Logic Execution Environment High throughput, low latency event processing. Built-in support for HA and scalability Asynchronous support & Event oriented Elaborated event distribution mechanism (with priority)‏ Mapping of events and method invocation on components Creates components instances in response to initial events Independent of underlying networks through Resource Adaptors High performing platform for event driven applications SLEE is complementary to Java EE 4
