# How BENOCS uses ClickHouse to monitor network traffic for the world’s biggest telcos

**[ClickHouse](https://daily.dev/sources/clickhouse)** · 5 min read · 0 upvotes · 0 comments

## Summary

BENOCS, a network analytics company serving major telcos, explains how they use ClickHouse to process dozens of terabytes of network traffic data daily. Two key ClickHouse features drive their architecture: fast time-based indexing via MergeTree tables (enabling DISTINCT SELECT queries that skip irrelevant data in seconds) and ASOF joins for fuzzy temporal matching across feeds with different time resolutions. Together these enable a self-healing push pipeline that handles late or missing data feeds without halting processing.
