PROFILE
Sergey Matov
Over thirteen months, contributed to the githedgehog/dataplane repository by building and enhancing a high-performance network dataplane focused on observability, reliability, and maintainability. Delivered features such as a gRPC-based configuration backend, Prometheus metrics integration, multithreaded packet processing, and BGP/BMP monitoring, using Rust and Python with extensive use of asynchronous programming and system-level concurrency. Refactored core modules for maintainability, optimized flow expiration with Tokio timers, and improved QoS handling for IPv4/IPv6. Addressed operational needs through robust logging, CLI enhancements, and persistent statistics, while ensuring compatibility with evolving dependencies. The work emphasized scalable design, testability, and actionable telemetry for operators.

Feb 1, 2026February 2026 (Month: 2026-02) – Dataplane delivered a backward-compatible minor release (0.11.0) and implemented QoS and visibility improvements that directly support SLA commitments and operator confidence. Key outcomes include preserving DSCP/ECN across ingress, encapsulation, and egress paths for IPv4/IPv6; enhancements to BGP neighbor status readability; and a corrective metric handling change to zero out deleted VPCs to prevent stale data in monitoring stores. The work emphasizes reliability, performance, and actionable telemetry for operators and downstream services.

Sep 1, 2025September 2025 — githedgehog/dataplane: Implemented a multithread kernel driver with a pipeline processing model to improve network throughput and scalability. The master thread handles TX/RX while worker threads process packets in parallel, enabling better CPU utilization under load. Backed by commit 5a4838246662dbd3c58721536307c1324d5a16d6 ('feat: multithread kernel driver'). No major bugs were closed this month; groundwork laid for further optimizations and reliability improvements. Business impact includes higher dataplane throughput, reduced queueing, and a scalable foundation for future features.
