Pub/Sub Event Hub

Technical Explanation

In traditional architectures, network functions communicated via synchronous point-to-point HTTP requests, causing tight coupling and cascade bottlenecks during traffic surges. The 6G Pub/Sub Event Hub organizes core signaling around an asynchronous event streaming log (built on NATS JetStream and Apache Kafka). Core functions publish state changes (such as 'UE_REGISTERED' or 'SLICE_CONGESTED'), and authorized functions consume events asynchronously at their own pace.

Key Functions

• Decoupling core network functions through high-throughput asynchronous event streaming
• Handling tens of millions of events per second with sub-millisecond end-to-end latency
• Persistent event logging allowing newly spun-up containers to replay recent events
• Eliminating cascading request timeouts and thread pool exhaustion during traffic spikes
• Native support for event-driven reactive microservice architectures across multi-clouds
