Service and Data Interoperability Environment

Overview

SADIE (libsadie) is a lightweight, transport-agnostic service middleware library designed to unify and simplify automotive service-oriented architectures. It provides a common abstraction layer across different automotive middleware protocols (SOME/IP, DDS, etc.) while maintaining high performance and minimal overhead.

Key Features

  • Protocol Agnostic: Write your services once, deploy them anywhere. Supports multiple transport protocols through a unified API:
    • SOME/IP (Scalable service-Oriented MiddlewarE over IP)
    • DDS (Data Distribution Service)
    • Custom transport plugins
  • Zero-Copy Design: Optimized for automotive use cases with minimal memory overhead and deterministic performance
  • Service Discovery: Built-in service discovery with support for:
    • Static configuration
    • Dynamic discovery (SD)
    • Service versioning
    • Instance management
  • Type Safety: Strong compile-time type checking with:
    • Pure C interface definitions - no IDL required
    • Automatic serialization/deserialization
    • ABI compatibility checking
  • Diagnostics: Rich introspection and monitoring capabilities:
    • Service health monitoring
    • Performance metrics
    • Bandwidth usage tracking
    • Latency measurements
