Mobicents Summit 2012 - Eduardo Martins - JAIN SLEE Update

  1. 1. JAIN SLEE Rio de Janeiro, Brasil October 2012
  2. 2. 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 cant communicate with components developed/deployed in other proprietary SLEE JAIN SLEE is the standardized JAVA SLEE
  3. 3. 1.2 Mobicents JAIN SLEE 2.x: Overview JAIN SLEE 1.1 JBoss AS 5 High Availability + Fault Tolerance with JBoss Cache 3.x High Performance (1200+ SIP UAS cps in a low class server) Low Latency Fault Tolerant Resource Adaptor API JAIN SLEE 1.1 Profiles Mapped to JPA on Hibernate Full control on how the data is persisted / loaded Management beyond JMX (Web Console, Twiddle CLI, JBoss ON Plugin) Misc Features Congesture Control Event Router Statistics Simplified Logging Configuration JAIN SLEE 1.1 Extensions
  4. 4. 1.3 Tools JBoss AS JMX Console GWT Management Console JBoss Operations Network Console Twiddle Command Line Interface
  5. 5. 1.4 Development Tools Eclipse SLEE Plugin Apache Maven2 Plugins, Repositories, Dependency Management, Archetypes Apache Ant Scripts
  6. 6. 1.5 Resource Adaptors JAIN SIP (with Early Dialog Failover) (Apache) HTTP Client HTTP Servlet (requests on a specific servlet are transformed in JSLEE events) JAIN MGCP XCAP Client (proprietary API) XMPP Component & Client (Extended Smack API) Diameter Base, Sh Client, Sh Server, CCA, Rf, Ro, Cx/Dx, Gq, Gx, Rx, S6a SMPP v5 JCC MAP JDBC TFTP Server MS Control
  7. 7. 1.6 Application Enablers Reusable components (SBBs), which provide high level and easy to use interfaces HSS Client REST Client SIP Event Publication Client SIP Event Subscription Client XDM Client
  8. 8. 1.7 Added Value Remote SLEE Connection Tool (Java EE event firing into remote SLEE) Media Server 2.x SIP Load Balancer Fault Tolerant Diameter Stack SS7 Framework
  9. 9. 1.8 Telscale SLEE 6.x Based on Mobicents SLEE 2.x Only production quality components Exclusive extras (e.g. SNMP monitoring) Extensive QA Better documentation resources Professional services  Support  Training  Consulting Choice between JBoss AS and EAP as underlying Java EE
  10. 10. 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)
  11. 11. 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
  12. 12. 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
  13. 13. 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).
  14. 14. 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
  15. 15. 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
  16. 16. 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
  17. 17. 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
  18. 18. 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
  19. 19. 4.1 Roadmap 3.0.0.BETA1 (Dec 2012)  JBoss AS 7  TCAP & ISUP Ras (along with SS7 2.x)  Media Server 3.x 3.0.0.BETA2 (Mar 2013)  Cluster 3.x (AS7 + Infinispan)  Diameter 2.x 3.0.0.RC1 (Jul 2012)  Annotations  EclipSLEE 3.x  Web Console 3.x 3.0.0.FINAL (Oct 2012)
