Time to market and reduced development cost

Why are Communications Applications Converging on Java Containers? • Telco apps moving to component based architectures • Desire to use Standard, Off-the-shelf container – Write-once, run-anywhere • Container provides important infrastructure services – Higher level abstractions for State management, Transactions, Security, Resource pooling, … • Focus on core value-add application logic • Leverage large community of Java developers • Leverage enterprise development tools, test suites, …

SLEE=ServiceLogicExecutionEnvironment Low latency and high throughput application environment for event processing – Latency < 100 ms – 100's to 1000's of events per second Event orientated Designed for stringent requirements of core network signaling application Designed to allow implementations to support scalability and availability through clustering

JAIN SLEE Benefits

SLEE reduces cost and improves time-to-market

• • •

High performing platform for event driven applications – Supports simple and complex applications – Applications deal with service logic only • System issues handled by container i.e. threading, transactions Standard application framework – Defined programming model – Object Orientated, asynchronous, robust and distributable Independent of underlying networks Asynchronous support – Elaborate event distribution mechanism (with priority) – Maps events to method invocations on components – Creates component instances in response to initial events

•

•

• •

Only industry standard Service Logic Execution Environment – Write-once, run anywhere for components

Availability and scalability through clustering – Versus traditional primary-secondary Easy to develop robust components – SLEE replicates state and provides transactional semantics – Strongly typed component interfaces and profile data Point of integration for multiple protocols and resources – One container, multiple resources, protocols – Easy to integrate new technologies

Event orientated component model – Elaborate event distribution mechanism (with priority) – Maps events to method invocations on components – Event processing components with strongly typed interfaces • Event types received and sends • Private state and state shared with other components • Component instances have no external and permanent identity • Simple and dynamic event subscription model – Container manages component lifecycle and Garbage Collection • Enables automatic component instance creation and deletion • Model is aware of event producer and consumer relationships • Important for robustness (avoid dangling component instances) Profiles for provisioned data – Easy to define, provision, and access profiles
