Netis Cloud Probe is a production-grade network packet capture and forwarding system designed to monitor traffic without requiring dedicated TAP or SPAN hardware. It consists of a high-performance C capture engine (cpworker), a Go daemon (cpdaemon) that manages worker processes and communicates with a central policy manager (CPM), and a Go CLI (cpctl) for manual control. The system supports multiple capture sources (libpcap, DPDK, pcap files) and output sinks (GRE, VXLAN, ZMQ, rotating files) with a configurable execution model (real-time or pipelined using a lock-free SPSC ring buffer). Configuration reload is handled via a state-machine protocol, enabling hot-swapping of tasks without packet loss. The codebase is multi-language (C, Go) with CMake and Mage build systems, comprehensive unit and integration tests, and bilingual documentation (English, Chinese). It is actively maintained with a recent commit and continuous integration.
GELLO is a general, low-cost teleoperation framework for robot manipulators. It uses a Dynamixel-based leader device to control various follower robots (Franka FR3, YAM, UR, xArm, Panda) in real-time via ZMQ-based distributed architecture. The system supports both simulation (MuJoCo) and real hardware, includes gravity compensation (FACTR) for YAM robots, and provides data collection pipelines for imitation learning. It also offers ROS2 integration for Franka FR3 with custom joint impedance controllers and gripper managers. The codebase is configuration-driven via YAML files and demonstrates strong engineering practices with pre-commit hooks, CI workflows, and reusable abstractions for robots, agents, and cameras.
VOLTTRON is a Python-based distributed control and integration platform for building and industrial control systems. It runs cooperating 'agents' (services) that communicate over a ZeroMQ/RabbitMQ message bus called VIP, supporting pub/sub, RPC, and peer-to-peer routing. The platform provides agent lifecycle management (volttron-ctl), a web UI, authentication, historians, and protocol drivers for Modbus, BACnet, and similar field protocols. In production it acts as a central hub for collecting sensor/controller data, executing actuation commands, and hosting automation logic.
