This repository implements a full 4G/5G telecommunications protocol stack (likely based on srsRAN) for software-defined radio applications. It provides implementations for User Equipment (UE), evolved Node B (eNB), gNB (next generation Node B), and Evolved Packet Core (EPC) network elements. The architecture follows a layered approach mirroring the telecommunications protocol stack (PHY, MAC, RLC, PDCP, RRC, NAS) with clear interfaces between layers. The system supports various SDR hardware platforms through a plugin-based radio frequency abstraction layer and can be used to build experimental 4G/5G networks for research and development. Key entry points include main.cc files in each application directory (srsenb, srsue, srsepc, srsgnb) and example applications in lib/examples/.
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.
