Executive Summary + +This document describes the design and implementation of alternative transport mechanisms for the Telemetry 2.0 (T2) Common Library, successfully decoupling it from RBUS dependency. The solution introduces pluggable transport backends including Unix sockets and POSIX message queues, while maintaining full backward compatibility with existing RBUS implementations. + +### Key Achievements +- **✅ Zero RBUS Dependency**: Eliminated mandatory RBUS dependency for telemetry clients +- **✅ Improved Performance**: Direct IPC mechanisms reduce overhead and improve throughput +- **✅ Enhanced Flexibility**: Three transport options for different deployment scenarios +- **✅ Maintained Compatibility**: Zero breaking changes to existing public APIs +- **✅ Container Support**: Full containerized application support with proper queue mounting + +--- + +## 2. Problem Statement + +The original T2 Common Library had a hard dependency on RBUS for communication between telemetry clients and the daemon. This created several challenges: + +- **Tight Coupling**: Applications required RBUS infrastructure for simple telemetry needs +- **Performance Overhead**: RBUS abstraction layers impacted event transmission speed +- **Deployment Complexity**: RBUS required additional system resources and configuration +- **Limited Portability**: Restricted deployment to RBUS-enabled environments +- **Container Limitations**: RBUS complexity hindered containerized deployments + +--- + +## 3.
