2. 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

4. 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

Familiar to HTTP servlet programmers because it leverages the well know servlet model to develop SIP applications.
Defines high-level objects
Container provides value-adds such as protocol stack, state management, proxy & b2bua capabilities, etc.
Ability to mix SIP Servlets and Java EE components to add rich media interactions to enterprise.
Application Composition through the Application Router
Declarative or programmatic security
Defined by the JCP v1.1 (JSR 289) approved by EG
