# Altos Technologies

> Ottawa software firm. Custom software and systems integration: telecom-scale load, Diameter Gx/Gy control plane, packet brokers, and Kafka/ClickHouse pipelines at 10 million events per second. Proudly Canadian.

Altos Technologies is based in Ottawa, Ontario, Canada. Contact is email only: office@altostech.ca. Response within 24 hours. An NDA will be signed if asked. Clients talk to product and tech people, not account managers. Recent work is anonymized under NDA; client names are not published.

What we do:

- Performance testing — real load, bottlenecks, production hold; Java, Kafka, Redis. Includes high-performance computing when the problem is compute at scale.
- Big data and analytics — ingest, transform, store, query, including streaming; Kafka, ClickHouse, Redis, Elasticsearch.
- Software-defined networks — custom aggregation and load balancing, overlay handling (VLAN, MPLS, GTP), stateful flow inspection; P4, Tofino, DPDK.

Recent work (order of magnitude, anonymized):

- IP-flow load generation: ~10 million flow events/s, ~1 million concurrent mobile subscribers, realistic device identifiers, cell movements, applications. Kafka, Redis, Java.
- Kafka to ClickHouse: replaced CSV at ~100 thousand events/s with Kafka, Protobuf, Kafka Streams, ClickHouse; sustained 10 million events/s on less hardware. Real-time enrichment from the control plane (location, device identity on IP-flow records). Performance-testing framework and OpenTelemetry.
- Diameter Gx/Gy PCEF-style control plane plus Gx/Gy test server; high availability; 50 thousand control messages/s.
- Packet broker on 100G Edgecore: both directions of a flow to the same DPI engine, then back to the correct port.

How we work: Agile iterations. Discover, Design, Develop, Test, Release.
