Overview
Micro JainSlee is a high-performance event-dispatching container built for mission-critical telecom and core banking workloads. It combines the concurrency model of JAIN SLEE with the modern runtime of Java 25 and Quarkus, delivering deterministic latency and massive throughput for signaling, transaction processing, and IoT event streams.
Container Architecture
Event-dispatching core: Resource Adaptors feed the Event Router; SBBs fire events back through Activity Contexts.
Key Features
- Java 25 + Virtual Threads: Millions of concurrent sessions with minimal memory overhead.
- Quarkus Native Optimizations: Fast startup, low footprint, and cloud-native deployment.
- Active-Active Fault Tolerance: Stateless event routing with no single point of failure.
- Carrier-Grade Latency: Designed for SS7, Diameter, and HTTP signaling workloads.
- Modular SBB Model: Reusable Service Building Blocks for rapid service creation.
Use Cases
- SS7/USSD signaling gateways
- Core banking transaction routers
- IoT event ingestion hubs
- MVNO core network functions
Status
Micro JainSlee is available in a production-grade edition. The public repository reflects the R&D baseline; enterprise features such as clustering, HA replication, and 24/7 support are delivered under a commercial license.
