PROFILE
Manish Vachharajani
Over the past year, contributed to the githedgehog/dataplane repository by building and evolving a high-performance, modular network dataplane with deep integration for Kubernetes and advanced routing features. Leveraging Rust, Go, and Python, delivered over 100 features including robust NAT and BGP configuration, scalable packet processing pipelines, and dynamic routing with BFD support. The work emphasized memory safety, concurrency, and testability, introducing abstractions for flow management, LPM-based routing, and gRPC-driven configuration. Enhanced CI/CD pipelines and documentation ensured maintainability and onboarding ease, while Kubernetes CRD integration enabled automated, reliable deployments across cloud-native environments, supporting both IPv4 and IPv6 networking.

Jan 1, 2026January 2026 highlights: NAT robustness and Kubernetes integration for dataplane, and a major release with BFD support. Key outcomes include stabilizing Stateful NAT with a default idle timeout, adding Kubernetes NAT handling with a new NAT blocks processor, and expanding test coverage with unit tests. In addition, the dataplane was released as version 0.10.0 to include the BFD feature for improved dynamic routing and faster link-failure detection. These changes enhance reliability in Kubernetes-based deployments, reduce NAT-related incidents, and improve failover performance.

Dec 1, 2025December 2025 dataplane monthly summary (githedgehog/dataplane). Focused on stabilizing the build, expanding Kubernetes interface integration, and enabling robust CRD-based runtime configuration. Key items include build stabilization by reverting the duplicate rustflags fix to restore prior behavior in RUSTFLAGS usage for language analyzers; network improvements with FromStr parsing for Mac and SourceMac; substantial Kubernetes interface codegen and type system work via the new k8s-intf crate and bolero generators (interfaces, bgp neighbors, GatewayAgent, and logs) with type derivations and data-model fixes; end-to-end CRD to Underlay config conversions including Vpc conversion for GatewayAgentVpc and broader CRD coverage for Expose, Overlay, Device, TraceConfig, and ExternalConfig; and operational improvements around config processing, status patching, and build performance. All of this adds up to stronger runtime configuration, safer deployments, and higher confidence in automated provisioning across Open Network Fabric components.

Oct 1, 2025In Oct 2025, delivered NAT configuration support in VpcExpose and introduced gRPC NAT config conversion to the internal external representation, enabling pipeline usage of NAT settings. Implemented a new nat field, refactored NAT inclusion/exclusion rules for readability and future NAT configurations, and preserved backward compatibility when NAT config is present or absent. No major bugs were reported this month; the work focused on feature delivery, stability, and paving the way for NAT-driven workflows in pipelines. Business value: provides flexible, scalable NAT configuration management and accelerates deployment pipelines with NAT-enabled configurations.

Sep 1, 2025Month 2025-09: Delivered a series of architectural and feature enhancements to the dataplane, focusing on robust flow management, scalable performance, and improved testability. Key outcomes include decoupling flow metadata by extracting Flow-info into its own crate and extending PacketMeta with flow_info to enable FlowKey derivation; end‑to‑end flow management withflow table lookups and expirations integrated into the dataplane pipeline; modernization of the dataplane for multithreading via a pipeline factory and async Tokio worker threads; performance and testability gains from transmitting Box<Packet<_>> to reduce copies and expanding testing utilities (public Packet contract, IP address helpers, and test packet builders); and readiness for DPDK integration with Mbuf Send and PacketBufferMut Send.

Jul 1, 2025In July 2025, delivered a comprehensive LPM-based overhaul for the dataplane, migrating core routing prefix handling to a new LPM crate, exposing core prefix types, and integrating with routing, mgmt, and nat. This work replaced the fragile iptrie-based approach, enabling faster lookups and more reliable routing decisions with a cleaner, more maintainable codebase.

Jun 1, 2025June 2025 – githedgehog/dataplane monthly summary focusing on business value, reliability, and scalable architecture: - Key features delivered and configuration hardening across Mgmt, Routing, and data-plane adapters, with a stable refactor path and testability improvements. - Major bug fixes addressing correctness of VTEP/MAC handling, converter serialization, and VTEP CIDR enforcement, reducing misconfigurations and operational incidents. - Architectural and tooling improvements enabling faster iteration, better test isolation, and easier maintenance (gRPC converters modularized per module, gateway-proto version management, and CI/test stability tweaks). - Packaging and observability improvements to support debugging and container workflows (dataplane-cli included in build image; debug-env builds) and CI reliability (reconcile fuzz tests and dpdk-sys updates). Business impact: higher confidence in network provisioning, improved policy fidelity (IPv4/IPv6 advertConfig, L2VPN/EVPN advertise behavior), and reduced time-to-troubleshooting with clearer module boundaries and better test coverage. Technologies/skills demonstrated: Rust refactor and quality improvements; gRPC converter modularization and per-module file architecture; protocol modeling with PartialEq/Eq; config validation (MTU, VTEP, IP/MAC), and build/integration tooling.
