1.1 JAIN SLEE: Introduction Low latency and high throughput application/service

environment for event processing

Designed for stringent requirements of core network signalling application, and to support scalability and availability through clustering

The environment provides common behaviour to all services:

Managing component life-cycle (install/activate/deactivate/uninstall,…)

Generating traces & alarms, managing resources, user statistics;

Common behaviour is not re-developed for each and every service, the service developer only cares about service logic

The necessity to introduce SLEE as a standard:

Components cannot be reused / dependency on vendor

Components developed / deployed on one proprietary SLEE can't communicate with components developed/deployed in other proprietary SLEE

JAIN SLEE is the standardized JAVA SLEE

1.2 Mobicents JAIN SLEE 2.x: Overview JAIN SLEE 1.1

1.7 Added Value Remote SLEE Connection Tool (Java EE event firing into remote

SLEE)

Media Server 2.x

2.1 Achievements Mobicents SLEE 2.x

“Bullet Proof” SLEE Core

1 New JAIN SLEE 1.1 Extension

3 New Resource Adaptors

1 New Application Enabler

2 New Example Applications

EclipSLEE 2.x

Web Console 2.x

20+ Major Features Developed

80+ Minor Features & Fixes

Community involvement on bug fixes

~7000 downloads since Sochi (10 months)

2.2 Shortcomings

Red Hat Telestax transition

Mobicents 3.x No Progress

Only 2 Binary Releases

Code Contributions

Still almost null on new features development

Weak developer documentation does not helps

3.1 Enhanced SLEE Core

Smooth upgrades of SLEE services with zero downtime

Core deploy-config.xml resource, which admins may use to define Resource Adaptor Entities out of deployable units

Support for period purge of canceled timer tasks

Better classloading deadlock prevention

Configurable timeouts for EventContext suspension

Optimized sbb entity ordering when routing events, which prevent transaction timeouts due to locks

Enhanced container state dump logging

Enhanced log4j default configurations

Reworked (AC) event queues

3.2 Enhanced ActivityContextInterface Extension

Allows SBBs to suspend event routing on an AC, feature only available to RAs on JAIN SLEE 1.1

Critical when a SBB attaches to an AC, then interacts with a non tx aware RA, which fires an event on the AC as follow up (which without AC suspension could be routed before SBB attachment is commited, missing delivery).

3.3 Resource Adaptors SIP RA

Several bugs fixed

Faster stack

Easier logging configuration (done through log4j)

New Diameter S6a RA

Stable release of SS7 MAP RA

MGCP RA

Updated stack

RA logic optimizations

New MS Control (JSR 309) Resource Adaptor

Stable release of JDBC RA

3.4 Application Enablers

New REST Client enabler

Easy interaction with web services, including Twitter and Facebook

Stable releases for SIP Subscription Client, SIP Publication Client and XDM Client enablers

3.5 Application Examples

SIP JDBC Registrar

Rework of the old SIP Services example, that demos the usage of the JDBC Resource Adaptor, to manage the state of a SIP Registrar server

MS Control Demo

Example of MS Control Resource Adaptor usage, handy for developers wanting a quick start on the new media control API

3.6 Web Console The reborn of the old but much missed Mobicents SLEE 1.x

GWT based Web Console

SLEE management

SLEE start/stop

DU (un)deploy

Component (de)activation

Component (re)configuration

SLEE monitoring

Usage Parameters

Traces & Alarms

SLEE state monitoring & management

AC list & removal

SBB Entity list & removal

3.7 Enhanced EclipSLEE Support for Fault Tolerant Resource Adaptors

Higher level wizard for project creation

Support for event handler methods with custom SBB ActivityContextInterface

Support for event handler methods with EventContexts

Easy to add project dependencies, such as the platform RAs and Enablers
