CASE STUDY

Distributed Real-Time Routing Synchronization System

Enabled sub-second propagation of routing updates across a distributed telecommunications network, ensuring accurate call delivery immediately after number transfers.

Situation

Real-time call routing required each carrier to maintain a local copy of national routing data. However, synchronizing updates at scale posed significant performance and consistency challenges.

Solution

Designed a distributed synchronization architecture enabling event-driven routing propagation, high-throughput update ingestion, and low-latency replication across carrier-local routing environments.
